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 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, and rugged styling.
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 frequently use common G-Shock functions like the stopwatch, countdown timer, and alarms or more advanced functions like environmental (altimeter-barometer-compass-thermometer) sensors. 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 models 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 and G-Shock embraced that by often collaborating with other popular streetwear brands on special edition watches. Individual expression (choosing and identifying with certain models) and 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 brands. Most people are aware of its reputation for toughness and its popularity. G-Shock watches are often spotted in movies and TV shows, reflecting its real world popularity. Many people identify with the brand, are very satisfied with the G-Shock watches they own, and G-Shock becomes a part of their life. Some people remain loyal to a certain model and one watch while others collect as many as possible. For many people it is a combination of all these factors. G-Shock is basically many things to many people. Because it offers such a large selection of versatile watches, G-Shock has a universal appeal that is not limited by age, social status, or country.
Yes, many do. G-Shock is not an official military issue watch but many soldiers around the world use it. There is evidence that military units around the world including the Navy SEALs 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 rescue personnel.
Yes, but those with smaller wrists should look into the G-Shock S Series and Baby-G line.
If the idea of possibly going 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, at least for the all-digital models.
“Atomic timekeeping” when referring to G-Shocks means the inclusion of the Multi-Band 6 time-adjustment feature. The somewhat misleading term 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 radio signals Multi-Band 6 watches receive. With Multi-Band 6 the watch automatically syncs itself daily through the reception of radio signals that are broadcast by 6 stations worldwide. So basically it is syncing with atomic clocks via radio transmission. This allows the watch to be as accurate as possible on a daily basis. See the following links for range informtion: North America, Europe.
Yes, though Casio’s official water resistance chart might suggest otherwise, G-Shock watches can handle recreational scuba diving and you shouldn’t have any problems unless you are diving very deep. What is very deep? We’d say deeper than 60-90 meters, though you can probably go beyond that. Some say you shouldn’t press the buttons underwater but some do it without incident. If you are going to dive to extreme depths regularly and want peace of mind then you should consider the Frogman which is ISO-certified for 200M. See the excellent post “The Water Resistance Myth Vs The Reality!” for more about how G-Shock watches are underrated, but keep in mind it is talking about the all-digital G-Shock models. It should be noted that G-Shock does test its watches by using a machine that simulates water pressure at a 200-meter depth and that G-Shock buttons are tested for underwater use as well.
Casio has been expanding its market with more expensive timepieces, several of which are considered luxury models. Several factors may contribute to the higher prices of high-end G-Shock watches: use of premium materials like sapphire crystal, inclusion of advanced technology like GPS signal timekeeping, more complex designs with analog subdials and shock/g-force/vibration resistance for analog movements, more advanced and labor-intensive manufacturing processes, production in Japan, and smaller production runs at Yamagata Casio’s Premium Production Line with the most skilled employees.
Most department stores such as Macy’s carry G-Shock and Baby-G watches. G-Shock watches can also be found at Walmart, Sam’s Club, and Costco but these stores usually only have a few models available. 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 much.
G-Shock watches should be easy to find in Japan. Based on our firsthand experience we would recommend any BIC Camera store. The official 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.
Casio usually announces new G-Shock models at the start of every month. These are usually unique color variations of existing models or special limited editions and collaboration models. There are usually a few completely new watch models introduced each year.
Because of the way new G-Shock releases are rolled out, there are many Asian sellers that cater to overseas buyers on sites like eBay and Amazon. The new G-Shock models become available in Japan and Asia first, and they arrive in the U.S. later, so if you want to get a new model as early as possible you need to buy it as an import. Also there are some models that are exclusive to Japan and are not released in the U.S.
Yes, all G-Shock watches feature English displays exclusively.
English G-Shock instruction manuals are available from Casio here.
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. If they are not blatant fakes, they will still look a little “off” with the lettering and LCD display not looking quite right and the watch appearing to be cheaply made. 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. It’s generally not a problem when looking for authentic G-Shock watches on eBay and Amazon and you should not experience bait and switch scams on these sites. If it does happen then be sure to demand a return/refund and report the seller. Beware of older limited edition Bathing Ape 6900 models which are common fakes and fake collaboration GA-110 analog-digital models from Thailand.
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. However this card is often not stamped at all. This should not be a problem if the watch was sold by an authorized seller and you have a proper receipt. There are some Amazon third-party sellers who are authorized Casio dealers, but others may not be. For eBay, check the description for warranty and authorized seller status, and for overseas purchases check to see if there is an international warranty. The Amazon product description will show the warranty status and it will be either be a 1-year Casio warranty or a 2-year Asurion warranty, which also covers purchases from Japan-based sellers. eBay is now offering 2 or 3 year protection plans from Assurant at an additional cost. If a watch breaks and it is not under warranty, it is still possible to send it to a Casio service center but you will be charged for repairs.
