The '''G-Shock''' is a line of [[watch]]es manufactured by the Japanese electronics company [[Casio]], designed to resist mechanical stress, shock and vibration. G-Shock is an abbreviation for ''Gravitational Shock''. The watches in the G-Shock line are designed primarily for sports, military and outdoors-oriented activities; all G-Shocks have a [[chronograph]] feature, 200 metre [[Water Resistant mark|water resistance]] and an [[Alarm clock|alarm]], with either a digital display, analogue display or a combination of analogue and digital displays. Other features such as a countdown timer, [[world clock]], and a backlight are included in most models. Newer high-end models in the line also feature [[GPS]], directional, pressure and temperature sensors, [[Radio clock|radio-controlled time adjustment]] (known as '''WaveCeptor''' or '''Multi-Band''') and [[Bluetooth]] time adjustment achieved by connecting the watch to a smartphone via a dedicated application.

==History==
[[File:DW-5000.jpg|thumb|The DW-5000C G-Shock (fitted with an aftermarket bezel)]]
The G-Shock was conceptualized in 1981 by Casio engineer Kikuo Ibe when he bumped into a pedestrian, and the mechanical watch given to him by his father popped off of his wrist and shattered on the ground.<ref>{{cite web|url=https://www.vice.com/en/article/even-legendary-watchmakers-get-anxious-about-lost-time/|title=A Legendary Watchmaker Describes His Greatest Regrets|date=9 January 2018|first=Wilbert|last=Cooper|publisher=Vice Media Group|access-date=9 January 2021}}</ref> The G-Shock then was conceived as a watch which would have "triple 10" resistance, meaning it would have a battery life of 10 years, have a water resistance of 10 bar and could survive a fall of 10 meters.<ref>{{cite web|url=http://www.nippon.com/en/views/b00105/|title=Lasting Popularity for a Tough Watch - The History of Craftsmanship Behind Casio's G-Shock|author=Andō Masahiro|date=2011-10-03|access-date=21 February 2016}}</ref>

A team of three individuals was selected by Ibe which was known as "team tough". The team had assembled and tested nearly 200 prototypes but were still not able to achieve the conception criteria. During a visit to a playground, Ibe discovered that in a rubber ball, the centre of the ball does not suffer the effects of the shock during a bounce on a rough surface, which gave him the idea to implement that concept into the watch. With that in mind, the team set out to develop a watch using such a concept and in April 1983, the first G-Shock, the DW-5000C, was launched.<ref>{{cite web|url=http://thestar.com.my/lifestyle/story.asp?file=/2008/9/23/lifeliving/2042152&sec=lifeliving|title=Smashing success|archive-url=https://web.archive.org/web/20110622092108/http://thestar.com.my/lifestyle/story.asp?file=%2F2008%2F9%2F23%2Flifeliving%2F2042152&sec=lifeliving|archive-date=22 June 2011|url-status=dead|df=dmy-all|access-date=23 December 2019}}</ref><ref name="Corporation2003">{{cite journal|url=https://books.google.com/books?id=eQAAAAAAMBAJ&pg=PA24|title=Popular Science|author=Bonnier Corporation|journal=The Popular Science Monthly|date=September 2003|publisher=Bonnier Corporation|page=24|issn=0161-7370}}</ref><ref name="Borne2005">{{cite book|url=https://books.google.com/books?id=tSHjYg17_HkC&pg=PA250|title=Men's Watches|author=Herve Borne|date=1 January 2005|publisher=Silverback Books|isbn=978-2-7528-0242-2|page=250}}</ref><ref>{{cite web|url=https://edition.cnn.com/style/gallery/10-watches-that-changed-the-world/index.html|title=10 watches that changed the industry: The Casio G-Shock|author=Jack Forster|date=30 June 2015|publisher=CNN}}</ref>

The shock-resistant design on the original G-Shock has ten layers protecting the [[quartz clock|quartz timekeeping]] module,<ref name="Corporation2003" /> including a [[Polyurethane|urethane]] rubber bumper, the [[stainless steel]] case, the hardened mineral glass watch crystal, the stainless steel screwed down caseback, and the "floating module" where the quartz mechanism floats free in a urethane foam cradle, with the outer buttons and LCD module attached with oblong button shafts. The strap of the watch is also designed to protect the module during a fall.<ref name="gp">{{cite web|url=https://gearpatrol.com/2013/10/15/icon-casio-g-shock/|title=The History of the Casio G-Shock|date=2013-10-15|first=Ed|last=Estlow|publisher=Gear Patrol|access-date=20 May 2019|archive-date=17 July 2019|archive-url=https://web.archive.org/web/20190717042346/https://gearpatrol.com/2013/10/15/icon-casio-g-shock/|url-status=dead}}</ref>

Initial sales of the G-Shock line were slow in Japan as people preferred dress watches. In order to promote the G-Shock worldwide, the American division of Casio released a commercial in which an ice hockey player used a DW-5200C G-Shock as a [[hockey puck]] to demonstrate the toughness of the watch. The commercial gained negative publicity and Casio was accused of false advertising. A TV news channel then set out to conduct live tests on the DW-5200C to check whether it was as tough and durable as advertised. This involved repeating the action shown in the commercial. The watch survived the impact of the hockey stick, and the G-Shock gained popularity among the general public. The popularity of G-Shocks increased throughout the 1990s. By 1998, Casio had released more than 200 different G-Shock models, with worldwide sales at 19 million units.<ref name=":0">{{Cite web|url=https://www.g-central.com/casio-celebrates-100-million-g-shock-watches-shipped/|title=Casio celebrates 100 million G-Shock watches shipped – G-Central G-Shock Watch Blog|website=www.g-central.com|date=31 August 2017 |language=en-US|access-date=2018-01-03}}</ref>

In 1985, Casio released the DW-5500C, which was the first G-Shock to feature a mud-resistant structure. Called the G-Shock-II due to the new construction feature, it was nicknamed "Mudman" by collectors due to its mud resistance capabilities. Casio would then go on to release a mud-resistant line of watches in 1995 which would go on to be called '''Mudman'''.<ref>{{cite web|url=https://g-shiok.blogspot.com/2013/09/DW-5500C-1.html?view=snapshot|title=Flashback Friday: First 'Mud Resist' G-Shock a.k.a.

In 1989, Casio introduced the AW-500, which was the first G-Shock featuring an analog display with a digital sub display at the six o'clock position.<ref name="AW-500">{{cite web|url=https://www.g-central.com/aw-500-and-awm-500-first-analog-g-shock-watch-revival-and-full-metal-screw-back-edition/|title=AW-500 and AWM-500: Revival of First Analog G-Shock Watch and Full Metal Screw-Back Edition|date=2020-10-01|publisher=G-Central|access-date=2022-06-02}}</ref>

In 1992, Casio released the DW-6100 equipped with a temperature sensor thus making it the first G-Shock to be equipped with a sensor. The watch also featured a resin (plastic) case instead of the original stainless steel case of earlier models for improved shock resistance. This move would transition into most of the models in the subsequent years, with the original G-Shock square design also adopting the same construction. By the early 2000s, the G-2000 model marked the last standard G-Shock to use a stainless steel case, leaving only a few speciality models in the line-up featuring the traditional metal case construction.<ref>{{cite web|url=https://www.watchuseek.com/threads/casio-g-shock-g-2000-model-line-2000-2001.607706/|title=Casio G-Shock G-2000 model line (2000/2001)|date=2011-11-09|access-date=2022-06-01}}</ref><ref name="G-Shock">{{cite web|url=https://g-shock.co.uk/cms/page/view/page_id/10|title=History|publisher=Casio|access-date=2022-06-01|archive-date=27 May 2022|archive-url=https://web.archive.org/web/20220527130726/https://g-shock.co.uk/cms/page/view/page_id/10|url-status=dead}}</ref>

In 1993, Casio introduced the DW-6300 Frogman, which was the first ISO 6425 certified diver's watch in the G-Shock lineup.<ref>{{cite web|url=https://shockbase.org/watches/subseries_dyn.php?series=6300&subseries=DW-6300&modul=1084|title=Series 6300 ::: Subseries DW-6300|access-date=2022-06-01}}</ref><ref name="G-Shock"/> The Frogman also marked the start of the MAN or "master of G" line of G-Shocks which was used to introduce new features and functions in the G-Shock lineup. Notable watches which introduced such features are as follows:
* DW-8600 Fisherman (1996): First G-Shock to include a tide graph and moonphase feature. This model was a precursor to the more popular Gulfman series first introduced in 1998.<ref>{{cite web|url=https://www.watchuseek.com/threads/dw-8600-fisherman.471106/|title=DW-8600 Fisherman|date=2010-11-14|access-date=2022-06-01}}</ref>

In 1994, the DW-6600 model marked the transition to Electroluminescent backlight technology for G-Shock watches from backlights employing incandescent bulbs in earlier models.<ref name="G-Shock"/> The same year also saw Casio introducing the Baby-G branded G-Shock watches designed for women.<ref>{{cite web|url=https://www.casio.com/products/watches/baby-g|title=Baby-G|work=[[Casio]]|access-date=2019-09-16}}</ref>

In 1996, Casio released the MRG-100 (also known as the DW-8900 in some markets<ref>{{cite web|url=https://www.watchuseek.com/threads/i-found-a-new-dw-8900-mrg-100-in-a-store.149229/|title=I found a new DW-8900 (MRG-100) in a store!|date=2008-05-12|publisher=watchuseek|access-date=2022-12-24}}</ref>) under its premium MRG lineup of G-Shocks which was the first G-Shock watch to feature full metal construction. The "floating module" concept was retained by cushioning the module between the metal case and metal bezel of the watch and an air-tight glass packing was added to improve shock resistance. Initially featuring a digital display, the MRG line would go on to adopt a full analog display featuring stepper motors for each hand and would be slotted as the top-of-the-line premium G-Shock lineup.<ref>{{cite web|url=https://www.hodinkee.com/articles/the-g-shock-mrg-b2000-kachi-iro#:~:text=Launched%20in%201996%2C%20the%20MRG,the%20bezel%20and%20the%20case.|title=The G-SHOCK MRG-B2000 'Kachi-iro'|publisher=Hodinkee|access-date=2022-05-31}}</ref>

In 2008, Casio introduced the Tough Movement for high-end analog G-Shocks. The movement incorporates a light emitting diode (LED) photo receptor which analyses the position of the watch hands by the passage of light via a small hole in the dial. Every uneven reception of light by the phototransistor due to impact to the watch enables the stepper motors in the movement to correct the alignment of the hands requiring no manual adjustment. The hour, minute and second hands feature separate motors in order to allow for quick adjustment of the watch.<ref>{{cite web|url=https://www.ablogtowatch.com/casio-raises-the-bar-again-with-tough-recalibrating-radio-controlled-movement-using-led-precision-system/|title=Casio Raises The Bar Again With Tough Recalibrating Radio Controlled Movement Using LED Precision System|date=2008-08-03|access-date=2022-06-02}}</ref>

A similar series to the Baby-G called the G-Shock Mini was introduced in 2009. It is 30% smaller than a regular G-Shock and was originally marketed for women. However, they were later released in unisex variants intended for people who have smaller wrists. This series was later replaced by the S-Series in 2014.<ref>{{cite web|url=https://www.g-central.com/g-shock-mini-watches-are-still-available/|title=G-Shock Mini watches|work=G-Central|access-date=2019-09-16|archive-date=1 August 2020|archive-url=https://web.archive.org/web/20200801090507/https://www.g-central.com/g-shock-mini-watches-are-still-available/|url-status=dead}}</ref><ref>{{cite web|url=https://www.casio.com/news/detail/g-shock-unveils-the-s-series|title=G-SHOCK Unveils The S Series|date=2014-12-31|publisher=[[Casio]]|access-date=2022-05-31}}</ref>

In 2013 in order to celebrate thirty years of the G-Shock, Casio arranged a party in New York and showcased new models as well as various prototypes of upcoming models. The party included a performance from rapper [[Eminem]].<ref name="gp"/> A similar event was held on 9 November 2023 for the 40th anniversary of the brand featuring a performance from the Colombian artist [[J Balvin]] with the founder of the brand Kikuo Ibe also in attendance.<ref>{{cite web|url=https://gshock.casio.com/us/40th/event/jbalvin-concert-shocktheworldnyc/|title=G-Shock 40th Anniversary Shock The World Live 2023|date=9 November 2023|publisher=Casio}}</ref> As part of the 40th anniversary celebrations, Casio also released an inspirational video package where Ibe visits his younger self back in 1982 in order to showcase the brand's origins and to promote the "Toughness Is Embracing Failure" motto of the brand.<ref>{{cite web|url=https://www.g-central.com/g-shock-creator-kikuo-ibe-visits-his-younger-self-in-1982/|title=G-Shock creator Kikuo Ibe visits his younger self in 1982|date=7 October 2023|publisher=www.gcentral.com}}</ref>

==Models==
[[File:Casio rangeman gpr-b1000-1er.JPG|thumb|left|Casio G-Shock Rangeman GPR-B1000 with GPS and with tough solar technology]]

The line of watches now includes [[atomic clock]], GPS and Bluetooth time synchronisation and tough solar technology. Many newer models feature metal (steel or titanium) bands and a mix of analogue-digital timekeeping, analogue timekeeping or digital timekeeping.

The DW models are standard battery-powered G-Shocks while GW models of the G-Shock come with either Tough Solar or Multi-Band atomic timekeeping or both. Models with the "B" prefix in its model name before the number are Bluetooth enabled, while those having the "P" prefix in the model name before the number have GPS time reception or navigation capabilities.

Twice a year, the basic models are updated. New limited models are introduced more frequently throughout the year. Special models are released upon the anniversary celebration of the G-Shock brand and are sold through selected retail channels.

Casio also produces collaboration models, often with popular fashion brands and artists, like [[A Bathing Ape]] (Bape), [[Stüssy]],<ref>{{cite web |url=http://www.stussy.com/gshock-watches |title=Stussy x GShock Collaboration Watches |website=www.stussy.com |url-status=dead |archive-url=https://web.archive.org/web/20120109023500/http://www.stussy.com/gshock-watches |archive-date=2012-01-09}}</ref> [[X-Large (clothing brand)|Xlarge]], [[Eric Haze]], [[KIKS TYO]], Nano Universe, [[Levi Strauss & Co.|Levi's]], [[Lifted Research Group]], as well as [[Coca-Cola]], Pulp68 Skateshop, [[Lucky Strike]] and [[Marlboro (cigarette)|Marlboro]].

[[File:USMC-17563.jpg|thumb|right|A [[USMC]] serviceman wearing a G-Shock G-100 along with a depth meter]]
G-Shock watches are popular with [[mountaineers]], [[firefighter]]s, [[Emergency medical services|paramedic]]s, people working in the offshore, [[police officer]]s, [[astronaut]]s, [[film directors]] ([[Tony Scott]] was often pictured wearing a GW-3000B, as are [[Ron Howard]] and [[Francis Ford Coppola]]) and [[military|soldiers]]. Ex-[[United Kingdom Special Forces|Special Forces-British SAS]] soldier [[Andy McNab]] mentions in several of his novels how his character Nick Stone relies on a G-Shock watch. According to [[Mark Bowden]]'s book ''[[Black Hawk Down (book)|Blackhawk Down]]'', the [[Delta Force|DELTA]] Operators wore G-Shock watches during the [[Battle of Mogadishu (1993)|combat events]] of 3 and 4 October 1993.

In 2009, Casio introduced the GW-M5610, a solar powered variant of the DW-5600 incorporating Multi-Band 6 time reception technology and a design homage to the original DW-5000C which was an update to the earlier GW-M5600 model.<ref>{{cite web|url=https://www.watchreport.com/review-of-the-casio-g-shock-gw-m5600bc/|title=Review of the Casio G-Shock GW-M5600BC|date=2009-01-18|access-date=2022-05-31}}</ref> The GW-M5610 would spawn many variants, the most notable being the GW-5000 which was a steel cased screw-back variant like the original G-Shock but featured diamond like coating (dlc) on the case and caseback and the GW-S5600 which featured Casio's first application of carbon fibre in a watch strap along with the use of titanium in the caseback, screws and buttons, making it the lightest G-Shock model available. The GW-M5610 series saw an update in September 2021 which consisted of replacement of the previous 3159 module with 3495 module. The new module replaced the Electroluminescent backlight for an LED backlight, made the home time visible in almost all watch modes and increased world time cities to incorporate cities having odd time differentials along with adding time-swap feature with the home time, the ability to set DD-MM and MM-DD formats for the date and day display, the ability to display the day of the week in different languages and added the ability to set the count-down timer to 1 second.<ref>{{cite web|url=https://casiofanmag.com/g-shock/gw-m5610/#General-Information|title=Casio G-Shock GW-M5610 — Immortal Classics with Solar Power & Radio Accuracy|date=11 February 2022 |access-date=2022-05-31}}</ref><ref>{{cite web|url=https://casiofanmag.com/g-shock/gw-s5600/|title=Casio G-Shock GW-S5600 Watches|access-date=2022-05-31}}</ref><ref>{{cite web|url=https://www.g-central.com/japan-only-g-shock-5000-series-watches-to-consider/|title=G-Shock GW-5000-1JF and Other Japan-only 5000 Series Watches|date=2015-07-09|access-date=2022-05-31}}</ref><ref>{{cite web|url=https://www.fratellowatches.com/casio-silently-updated-its-most-significant-g-shock-square/|title=Casio Silently Updated Its Most Significant G-Shock Square|date=2021-09-27|access-date=2022-05-31}}</ref>

In 2012, Casio released the GB-6900 and GB-5600 which were [[Bluetooth]]-enabled models of the G-Shock giving them the ability to connect to a smartphone via an app, allowing the users to adjust various functions of the watch using the phone and receive notification alerts of the phone on the watch. There was also a phone-find feature which allowed the users to find the smartphone with which the watch is paired in case it is misplaced. The phone would ring regardless of the ringtone setting on the press of a button on the watch. Casio claimed a battery life of two years on a single [[CR2032 battery]].<ref>{{cite web|url=https://www.theverge.com/2012/6/21/3032067/casio-bluetooth-g-shock-watch-gb6900-review|title=Casio G-Shock GB-6900 Bluetooth watch review|date=21 June 2012}}</ref> Since then, the Bluetooth technology has been incorporated in many models including high-end variants. The Bluetooth lineup would be further expanded to incorporate tough solar and multi-band atomic time reception with the GW-B5600 (basic resin model) and the GMW-B5000 (full metal screw-back cased models) in 2018.<ref>{{cite web|url=https://www.g-central.com/g-shock-gmw-b5000-metal-screw-back-bluetooth-solar/|title=Full-Metal G-Shock GMW-B5000: GMW-B5000D-1 & GMW-B5000TFG-9 Stainless Steel Screw-Back with Solar & Bluetooth|date=2018-03-01|access-date=2022-05-31}}</ref><ref>{{cite web|url=https://www.g-central.com/g-shock-gw-b5600-and-gw-b5600bc-tough-solar-bluetooth-resin-squares/|title=G-Shock GW-B5600 & GW-B5600BC: Tough Solar, Bluetooth, Multi-Band 6 Resin Squares with Resin and Composite Bands|date=2018-09-27|access-date=2022-05-31}}</ref> The series would later spawn a variant slotted in the MR-G lineup of premium watches called the MRG-B5000 which sported full titanium construction for the case and bracelet as well as a sapphire watch glass in 2022. The MRG-B5000 is the first square model to incorporate a multi-piece bezel for improved shock resistance.<ref>{{cite web|url=https://www.g-central.com/the-expensive-g-shock-mrg-b5000-looks-worth-it-in-this-video/|title=The pricey G-Shock MRG-B5000 looks worth it in these videos|date=2022-03-01|access-date=2022-05-31}}</ref>

In October 2020, Casio introduced the AW-500 and the AW-M500 which were a homage to the original AW-500, which released in 1989 as the first G-Shock incorporating an analog movement. The AW-500 model is similar to the original with some significant differences, such as a resin case compared to the original's stainless-steel screw back case. Neobrite lume on the analog hands on some models, an enhanced stopwatch featuring 24 hours measurement duration, an electroluminescent backlight and the hands located at the centre of the dial while the original AW-500 had the handset towards the top of the dial to make way for the digital display. The AW-M500 is a more premium model featuring full stainless-steel construction (i.e. case, bracelet and bezel) with the case being the same screw back design as the original AW-500, DLC coating on the inner case and case back, tough solar recharging technology with multi-band 6 radio wave time reception technology, stopwatch, countdown timer, world time mode with 39 time zones and 48 cities and 5 alarms. Unlike the base AW-500 model, the AW-M500 came with a dual LED backlight (one LED for the analog display and one LED for the digital display) and a hand-shift feature which moves the analog hands out of the way of the digital display to allow easy reading of the digital display for the user.<ref name="AW-500"/>

The GW-9400 Rangeman (introduced in 2013) and GWN-1000 Gulfmaster (introduced in 2014) models have a Triple Sensor with a digital compass, thermometer, and barometer/altimeter and were the first G-Shock watches to receive such technology. The MTG-S1000, GW-A1000, and GPW-1000 feature Triple G Resist which includes resistance to shock, [[centrifugal force]], and vibration. In 2014, Casio introduced the GPS Hybrid Wave Ceptor feature in the GPW-1000 Gravitymaster that allows the watch to synchronize the time through GPS signals and also adjust the time zone automatically. The MRG-G1000 and MTG-G1000 are also equipped with this feature.<ref>{{Cite web|url=https://www.g-central.com/mtg-g1000-new-g-shock-mt-g-with-gps-hybrid-timekeeping/|title=MTG-G1000 New G-Shock MT-G with GPS Hybrid Timekeeping – G-Central G-Shock Watch Fan Blog|website=www.g-central.com|date=8 September 2015 |access-date=2019-07-22}}</ref>

At Baselworld 2015, Casio introduced the "Dream Project" (G-D5000-9JR) concept which was a Casio G-Shock square having most of its parts constructed of 18 Karat solid gold as part of the 35th anniversary celebrations of the G-Shock lineup. The watch featured premium finishes throughout its construction without compromising the basic shock resistance of a G-Shock. In 2019, Casio introduced the production version of the Dream Project which featured an upgraded module now incorporating Bluetooth time reception capabilities in addition to the radiowave time reception and began taking reservations at select G-Shock boutiques in Japan. Thirty-five units of the Dream Project square would be produced, with each having a retail price of 7.7 million ¥ (69,500 US$ at 2019 exchange rates) excluding taxes making it the most expensive G-Shock watch at the time.<ref>{{cite web|url=https://watchesbysjx.com/2019/02/g-shock-pure-gold-18k-yellow-gold.html|title=Introducing the $70,000 G-Shock "Dream Project" in Solid, 18k Yellow Gold|access-date=2022-05-31}}</ref><ref>{{cite web|url=https://www.ablogtowatch.com/unboxing-solid-gold-g-shock-g-d5000-9jr/|title=Unboxing th Solid Gold G-Shock G-D5000-9JR 'Dream Project' at Topper Jewelers|date=2020-02-23|first=Zach|last=Pina|access-date=2022-05-31}}</ref>

In 2016, Casio released the GWN-Q1000 Gulfmaster, which was the first G-Shock to incorporate quad sensors (pressure sensor, temperature sensor, depth sensor and direction sensor). It was also the first G-Shock to feature horizontal calibration which allowed the compass to be operated while the watch is being worn by the user on the wrist. In addition to that, Casio offered every function offered on G-Shock models till date. The GWN-Q1000 is the only analog G-Shock to feature a depth sensor as well as the first G-Shock to have carbon reinforced polymer construction for the case.<ref name="Q1000">{{cite web|url=https://www.ablogtowatch.com/casio-g-shock-master-of-g-gulfmaster-gwnq1000-1a-watch-review/2/|title=Casio G-Shock Master Of G Gulfmaster GWNQ1000-1A Watch Review|date=2016-11-07|first=Ariel|last=Adams|access-date=2022-06-02}}</ref><ref>{{cite web|url=https://millenarywatches.com/casio-gulfmaster-gwnq1000-review/|title=Casio Gulfmaster GWNQ1000 Review & Complete Guide|access-date=2022-06-02}}</ref>

In late 2018, Casio introduced the newest addition to the G-Shock Rangeman series of models. The GPR-B1000 is a GPS centred model, which can use the GPS receiver to maintain the exact time, down to the second. This model also has triple sensors (altimeter, barometer and compass) as well as a backtracking function which allows the user to return to the same point from where he started the journey by the use of a map, a function which was previously exclusive for Casio's ProTrek line of watches. The watch also features Bluetooth connectivity which allows it to connect to a smartphone via an app and allows it to upload log data in the phone, download map information from the phone and also synchronise itself with the phone in order to keep perfect time. The watch comes without a replaceable battery. The battery is either charged by solar cells present on the face of the watch (called Tough Solar by Casio) or via a wireless charger supplied with the watch, a first for a Casio watch.<ref>{{cite web|url=https://techcrunch.com/2018/10/08/the-casio-rangeman-gpr-b1000-is-a-big-watch-for-big-adventures/|title=The Casio Rangeman GPR-B1000 is a big watch for big adventures|first=John|last=Biggs|date=8 October 2018 |publisher=Tech Crunch|access-date=2019-05-21}}</ref>

In 2019, Casio released the GA-2100 which took design inspiration from the original DW-5000C but now incorporated an analog-digital display. Due to the octagonal bezel shape bearing a strong resemblance to the Audemars Piguet Royal Oak, the watch was nick-named "CasiOak" by fans. The use of the carbon reinforced plastic in the watch case allowed the watch to have a thickness of 11.8&nbsp;mm, making it the thinnest G-Shock available as well as the lightest analog digital model with a weight of 51 grams. The aforementioned characteristics allowed the model to achieve increased popularity among collectors.<ref>{{cite web|url=https://www.hodinkee.com/articles/the-casio-g-shock-value-prop|title=The Value Proposition The Cult Classic Casio G-Shock GA2100 1-A-1 'CasiOak'|date=2020-01-28|first=Cole|last=Pennington|publisher=Hodinkee|access-date=2022-06-02}}</ref><ref>{{cite web|url=https://www.g-central.com/why-the-g-shock-ga-2100-is-so-popular-review/|title=Why The G-Shock GA-2100 Is So Popular (Review)|date=2020-03-23|publisher=G-Central|access-date=2022-06-02}}</ref><ref>{{cite web|url=https://www.dapperwork.com/casio-g-shock-ga-2100-reviews/|title=G-Shock GA 2100: 'Well Done' Casio|date=2021-11-02|access-date=2022-06-02}}{{Dead link|date=July 2025 |bot=InternetArchiveBot |fix-attempted=yes }}</ref> A solar powered model with Bluetooth time reception capabilities called the GA-B2100 was released in 2022.<ref>{{cite web|url=https://www.digitaltrends.com/mobile/casio-g-shock-ga-b2100-hands-on-features-price-photos-release-date/|title=The tech-boosted G-Shock GA-B2100 watch is a great buy|date=2022-04-28|first=Andy|last=Boxall|publisher=Digital Trends|access-date=2022-06-02}}</ref> The 2100 series of G-Shock would later go on to span a full metal variation, called the GM-B2100 in 2022.<ref>{{cite web|url=https://www.fratellowatches.com/hands-on-with-the-golden-casio-g-shock-casioak-gm-b2100gd/|title=Hands-On With The Golden Casio G-Shock "CasiOak" GM-B2100GD|date=21 February 2023|first=Jorg|last=Weppelink|publisher=Fratello Watches|access-date=30 March 2023}}</ref> An MRG variation based on the design called the MRG-B2100 was introduced in 2024.<ref>{{cite web|url=https://www.g-central.com/g-shock-mrg-b2100b-1a-first-2100-based-mr-g-series/|title=G-Shock MRG-B2100B-1A: First 2100-based MR-G series is a $4,800 CasiOak|date=28 May 2024|publisher=G-Central|access-date=26 June 2024}}</ref>

In October 2023, Casio announced the "Dream Project # 2" (G-D001) as part of their 40th anniversary celebrations. The watch was designed by a team of young designers and generative AI which designed a full metal structure with organic forms and shapes enhancing shock resistance and weight reduction without the need for rubber dampers. The watch also features a unique see through module having a main metal face plate, silicone cog wheels and 55 ruby bearings showing the internal working of the components. The solar powered module is powered by solar cell technology used in satellites with light powering the solar cells through a small gap in the date window. The watch case, case back and band are constructed entirely of 18-karat hand polished solid gold with the watch coming with time keeping features standard on many G-Shock models such as a chronograph, alarm, dual time display and multi-band 6 time reception technology. The watch comes with a special box with a slide-open door with perforations containing the model numbers of different G-Shock watches. The box also comes with a special LED light inside the box to keep the watch charged during storage. Only one unit was produced with the watch auctioned off at Phillips Auction House during '''The New York Watch Auction: NINE''' held in New York on 10 December 2023 with the winning bid amounting to US$400,050 (US$315,000 plus buyer's premium) making it the most expensive Casio and G-Shock watch ever produced.<ref>{{cite web|url=https://www.g-central.com/casio-officially-announces-dream-project-2-g-shock-g-d001-18k-gold-watch-designed-with-ai-assistance/|title=Casio officially announces 40th Anniversary Dream Project #2 G-Shock G-D001 18k gold watch designed with AI assistance|date=17 October 2023|publisher=www.g-central.com}}</ref><ref>{{cite web|url=https://gshock.casio.com/sg/g-news/new-releases/2023/G-D001/|title=G-SHOCK 40TH ANNIVERSARY DREAM PROJECT #2|publisher=G-Shock}}</ref><ref>{{cite web|url=https://www.g-central.com/the-one-of-one-gold-g-shock-g-d001-sold-for-400050-at-auction/|title=The one-of-one 18 karat gold G-Shock G-D001 sold for $400,050 at auction ($315K winning bid plus buyer's premium)|publisher=www.g-central.com|date=10 December 2023}}</ref>

==Multi-Band 6==
The Multi-Band 6 is a [[Radio clock|radio control]] technology first introduced on the GW9200 Riseman in 2008<ref>{{cite web|url=https://www.watchonista.com/articles/history/look-back-history-casio-g-shock|title=A look back at the history of the Casio G-Shock|date=2017-11-30|first=Rhonda|last=Riche|publisher=Watchoninsta|access-date=2020-07-06}}</ref> and is a successor to the Multi-Band 5 (which supported synchronisation with five atomic time transmitters around the world) and [[Casio Wave Ceptor|Wave Ceptor]] (which supported synchronisation with atomic time transmitters present in the United States and Japan only) technologies. G-Shock watches with Multi-Band 6 technology can synchronise with one of the six atomic time transmitters in the world in order to keep accurate time. The following is a list of the six atomic time transmitters:

; Japan

Watches can tune in to two locations:

The 40&nbsp;kHz signal from [[JJY]] at [[Otakadoyayama Transmitter|Mount Otakadoya]], near [[Fukushima, Fukushima|Fukushima]] (''Ohtakadoyayama'').

The 60&nbsp;kHz signal from the [[Haganeyama Transmitter]] at Mount Hagane (''Haganeyama'').

; China

Watches tune to the 68.5&nbsp;kHz signal from [[BPC (time signal)|BPC]] at [[Shangqiu]]. This is the newest additional signal; older multi-band 5 watches will not be able to connect to this signal, and must be upgraded to a newer multi-band 6 watch in order to synchronise from there.

; United States

Watches tune to the 60&nbsp;kHz signal from [[WWVB]] at [[Fort Collins]].

; United Kingdom

Watches tune to the 60&nbsp;kHz [[Time from NPL|MSF]] at [[Anthorn Radio Station|Anthorn]].

; Germany

Watches tune to the 77.5&nbsp;kHz [[low frequency]] time signal radio station [[DCF77]] at [[Mainflingen]].

==Guinness World Record==
On 12 December 2017, the G-Shock earned the [[Guinness World Record]] for the heaviest vehicle to drive over a watch. The officials from Guinness World Record drove a 24.97-[[metric ton|tonne]] truck over the Casio G-Shock DW5600E-1. The G-Shock is the first watch by any company being able to withstand the challenge.<ref>{{cite web|url=https://www.casio.com/news/detail/casio-g-shock-officially-breaks-guinness-world-records-title|title=Casio G-SHOCK Officially Breaks Guinness World Records Title|date=12 December 2017|work=Casio|access-date=6 June 2020}}</ref>

The Master of G series is the speciality line of G-shocks which were used to introduce new features that would eventually make their way to the standard production models. The lineup consists of:<ref>{{cite web|url=https://www.g-central.com/the-g-shock-master-of-g-buyers-guide/|title=Casio G-Shock 'Master of G' Buyer's Guide|date=2015-02-27|access-date=2022-05-31}}</ref>

===G-Lide Surfing editions===
[[File:G-Shock GLX-5600 (2621228586).jpg|thumb|left|Casio GLX-5600]]
These models were released in 1996, designed and specifically made for the surfing market. The countdown timers on these models were designed to count down for surfing competitions, while some of the later models have a yacht timer, moon and tide graphs so a surfer can keep track of the progress while competing on the water. Many of these models came equipped with a pair of strap adapters and a single one-piece resin or nylon band. These styles of band are also known as "crossband" in the Japanese domestic market. Resin bands for these models had open gaps or slits through the band. Casio refers to them as ''drainage slits''; the idea is that water will drain out with no problems while in action when surfing. Most of these series models had a translucent band. These models were branded as X-Treme for the Japanese domestic market.

====X-Treme Snow Board/Skateboard Editions====
These models are identical to the surfing editions, and also released in 1996. They were designed for snowboarding and skateboarding competitors and competitions. The only difference is that these models came with [[nylon]] [[velcro]] bands.
