G-Shock is a sports watch brand that is owned and manufactured by Casio Computer Company, Ltd. All current G-Shock watches are shock-resistant against impacts and water-resistant to 200 meters.
All current G-Shock watches (excluding the Baby-G and G-MS lines) are water-resistant to 200 meters (or 20 BAR). They are suitable for swimming, water sports, and recreational diving.
The first G-Shock was introduced in 1983. It was created by a team of engineers led by Kikuo Ibe who made it his personal mission to design an unbreakable watch. Ibe’s motto is “Never give up.”
G-Shock watches are known for their shock resistance, 200-meter water resistance, quartz accuracy, long battery life, digital functions, and rugged styling. Also, G-Shock continues to innovate with new technological features and new models added on a regular basis.
There are many reasons. One is utility which includes durability. People with demanding jobs and an active lifestyle want a watch that won’t break under pressure, performs reliably, and doesn’t get easily banged up. They may also use common G-Shock functions like the stopwatch, countdown timer, and alarms or more advanced functions like environmental sensors (altimeter-barometer, compass, thermometer). They may need a water-resistant watch, and G-Shock is very reliable in that area. Second is convenience. Some people may not really need such a tough watch or special functions but find features like solar charging, world time, and automatic time-syncing to be very convenient. G-Shock is designed to be a maintenance-free watch. Third is fashion. G-Shock watches are available in a variety of shapes and colors and even the basic black models have an attractive, rugged look. Though not its original intention, G-Shock became very popular in streetwear fashion in the 1990s and 2000s. G-Shock embraced and expanded that audience by collaborating with popular streetwear brands to release limited edition watches. Individual expression and the exclusivity with limited edition releases also factor into the fashion aspect. Fourth is history. G-Shock has been around for a very long time and has released a huge amount of watches, making it one of the world’s most recognizable and trusted brands. Most people are aware of its reputation for toughness and reliability. For many people, it is a combination of all these factors. Because it offers such a large selection of versatile, fashionable, and high-quality watches, G-Shock has a universal appeal that is not limited by age, social status, or nationality.
Yes, many do. There was a time when Navy SEALs were issued the G-Shock DW-6600. G-Shock is not an official military issue watch but many service members use it. There is evidence that military units around the world have purchased and distributed G-Shock watches to their members. G-Shock watches are commonly available to purchase at PX stores on military bases. G-Shock is also very popular with law enforcement and emergency rescue personnel.
Yes, smaller G-Shock watches like the DW-5600 can fit women’s wrists and women can even wear the larger models if they want to. Those with smaller wrists should look into the G-Shock S Series and Baby-G line.
If the idea of possibly going over 10 years without having to change the rechargeable battery appeals to you, then yes, you should buy a G-Shock with the Tough Solar feature. However it should be noted that non-solar G-Shock batteries tend to last a lot longer than their estimated life, depending on usage.
“Atomic timekeeping” when referring to G-Shock watches means the inclusion of the Multi-Band 6 automatic time adjustment feature. The somewhat misleading term (when applied to watches and G-Shocks) is used because atomic clocks (see link for the technical explanation of “atomic,” it does not mean “nuclear”) are used as a standard for the time distribution transmitters that broadcast the Multi-Band 6 radio signals. With Multi-Band 6, the watch automatically syncs itself daily through the reception of these radio signals that are broadcast by six stations worldwide. Basically, it is syncing the atomic clock time via radio transmission. This allows the watch to be as accurate as possible on a daily basis, assuming one is within range of a transmitter. (Not all countries and cities are within range.) The Multi-Band 6 feature is also referred to as “Wave Ceptor” and “Radio-Controlled,” and, as the Multi-Band 6 feature is usually paired with the Tough Solar feature, “Solar Radio.”
Yes, although Casio’s official water resistance chart might suggest otherwise, G-Shock watches can handle recreational scuba diving. Many people scuba dive with them and you shouldn’t have any problems unless you are diving extremely deep. What is extremely deep? We’d say deeper than 60-100 meters, though it’s very possible that you could go beyond that (see the DW-5600 and MRG-G1000 links at the end of the paragraph). Some people say you shouldn’t press the buttons underwater but some do it without incident (perhaps you should exercise more caution with this at deeper depths). If you are going to dive to extreme depths regularly (or just want the best rated water resistance on a G-Shock) then you should consider the Frogman series, which is the only G-Shock line that is ISO Diver certified for 200 meters. Its buttons are also tested for underwater use. G-Shock does test new models with a machine that simulates water pressure at a 200-meter depth. Casio has also produced videos of real world 200-meter depth tests with the affordable DW-5600 and the high-end MRG-G1000.
G-Shock has been expanding its audience and market with more expensive timepieces, several of which are considered luxury models which cost around a thousand dollars or more. Several factors contribute to the higher prices of these high-end G-Shock watches: the use of premium materials, the inclusion of advanced features, more complex designs, a more advanced and labor-intensive manufacturing processes, production in Japan (versus the mass-produced models made in Thailand and China), and smaller production runs at Yamagata Casio’s Premium Production Line.
Assuming all the characters before the last two extended ones in the example are the same, it is the exact same watch with the same features, and those last two characters refer to the market that the watch is meant to be sold in. JF stands for Japan. JR is for limited releases in Japan. CR and DR is for export outside Japan. ER is for Europe. While the watch is the same, it may come with different packaging and a different language for the instruction booklet, depending on where it is sold.
In the U.S., some department stores such as Macy’s carry G-Shock and Baby-G watches. Macy’s stores in high-traffic locations usually have a good selection of the latest models, but smaller Macy’s stores may not have as many. Many other chain stores also carry G-Shock. See G-Shock’s official list of authorized dealers but note that some authorized dealers may not be listed here.
G-Shock watches are easy to find in Japan at many stores. We recommend any BIC Camera store which has prices below the MSRP. The official G-Shock store in Tokyo is G-Shock Store Odaiba at 1-7-1 Daiba, Minato-ku, Tokyo, 135-0091. There is also an official store in Fukuoka at 1-2-74 Sumiyoshi, Hakata-ku.
New G-Shock watches are released on a monthly basis. Casio usually announces new G-Shock models at the start of every month in Japan. These are usually unique color variations of existing models or special limited editions and collaboration models. There are also a few completely new G-Shock watch models introduced throughout the year, and these all-new models seem to be increasing at a faster rate lately. Japan is usually the first country to announce and distribute the new releases to retailers, followed by other Asian countries a few weeks later, and then the U.S. and Europe and other areas around a month after the Japan release. However, recently we have begun to see other countries releasing some new models at the same time as Japan (and even before Japan in some cases).
Because of the way new G-Shock releases are rolled out in Japan and Asia first and delayed in western countries, there are many Asian sellers that cater to western buyers on sites like Amazon and eBay. We suggest waiting for the wider North American releases for better prices and the possibility of buying from an authorized seller (and we regularly update our Amazon and eBay links to North American sellers when possible), but there are some models that are exclusive to Japan or Asia and are not released in the U.S. at all.
Reasons why you should buy a G-Shock from Japan: 1. You can get the newest models earlier. 2. Some models are not released outside of Japan, or outside of Asia, and it may be the only way to get them. Reasons why you shouldn’t buy a G-Shock from Japan: 1. Watches bought from Japan will likely not include a Casio warranty in your home country so if the watch malfunctions outside of your return window you will be responsible for paying for repairs. For this reason we suggest buying the more expensive G-Shock models from authorized sellers in your home country (though it might be possible to buy an extended third-party warranty on Amazon and eBay if you are in the U.S.) 2. If the watch is due for a wider release, it may end up being available for cheaper in the U.S. later on. 3. If a limited edition collaboration model is due for a worldwide release, it is usually cheaper to buy the U.S. release.
Yes, all G-Shock watches feature English displays.
Do research before buying. Familiarize yourself with all the G-Shock models you might be interested in. A fake G-Shock should be easy to spot if you know what the real model looks like, though there are a lot of unauthorized replicas out there and some may require careful examination. If they are not blatant fakes, they will still look a little “off” with the lettering, LCD display, and other components not looking quite right. Stick to trusted and highly rated sellers and buy from sources that have a good return policy. Beware of prices that look too good to be true. Fake G-Shock watches are usually sold to people who are actually looking for cheap fakes, and scams online are not that common (though it can certainly happen). If you do receive a fake watch then be sure to demand a return and refund and report the seller. Beware of older limited edition Bathing Ape 6900 models on eBay and unauthorized GA-110 and DW-6900 collaboration watches from Southeast Asia.
Casio G-Shock watches come with a warranty card that is meant to be stamped by an authorized Casio dealer for the 1-year warranty. This card is often not stamped at all, but this is not a problem if the watch was sold by an authorized seller and you have a receipt that identifies the seller. Watches that are sold directly by Amazon.com and not a third-party seller include a 1-year Casio warranty. If it is a third-party seller on Amazon you should assume there is no Casio warranty included, but there may be some exceptions (see “Amazon Sellers who are Authorized Casio G-Shock Dealers“). Amazon also sells Asurion 4 Year Watch Protection Plans or SquareTrade Watch Protection Plans separately. Casio states that watches sold on eBay and other auction sites are not covered by a Casio warranty. eBay offers an optional 2-year protection plan from SquareTrade (with variable pricing). If a watch breaks and it is not under any warranty, it is still possible to send it to a Casio service center and pay for repairs.
No, G-Central is just a news blog and fan website and does not sell any G-Shock watches or parts. G-Central curates G-Shock selections on Amazon at
G-Central seeks to accommodate a worldwide, English-speaking audience and reports on G-Shock news and releases from around the world. The site can also be translated into different languages using the Google Translate tool at the bottom of every page or with the Google Chrome web browser. For the monthly G-Shock releases, we mainly focus on Japan, the Asia region, and the United States. (We are focusing more on Europe now as well.) We are aware that many of our readers are around the world in other countries and we try to cover regional news that would be of interest to them. As it would be impractical for us to report on every region or country’s monthly watch releases, we suggest following your country’s official G-Shock site for additional information on new releases. G-Central is meant to be a supplement to the official G-Shock sites and is not meant to be a replacement for them.
No, G-Central is independently owned and operated and is not an official representative or subsidiary of Casio or G-Shock. G-Central does not have a business relationship with Casio or G-Shock and cannot contact them for you.
When new models are first announced, they are usually not available until a few weeks later (sometimes longer if it is an early announcement). Please bookmark the page and check back later, as we are constantly updating previous posts with new information and shopping links. You may need to hit “refresh” in your browser to see the latest updates. New watches that are available to purchase are listed in our Shopping category (and listed in order of publication, so a recently updated post will not always appear at the very top). Watches that are available from North American sellers on Amazon with updated shopping links are also added to the Featured category, but sometimes a significant and in-demand Japan-only release will also be in this category.
Also, it is possible that you read an older article, and the watch is no longer available. Many of the special color series are only produced for a limited time and then discontinued.
