The G-Shock was conceptualized in 1981 by Casio engineer Kikuo Ibe when he inadvertently dropped and broke a pocket watch given to him by his father. The G-Shock was considered as a watch which would have "triple 10" opposition, which means it would have a battery life of 10 years, have a water obstruction of 10 bar and could endure a fall of 10 meters.
A group of three people was chosen by Ibe which was known as "group extreme". The group had gathered and tried almost 200 models yet were as yet not ready to accomplish the origination standards. During a visit to a jungle gym, Ibe found that in an elastic ball, the focal point of the ball doesn't endure the impacts of the stun during a bob on an unpleasant surface which gave him the plan to actualize that idea into the watch. In view of that, the group set out to build up a watch utilizing such an idea and in 1983, the main G-Shock, the DW-5000C, was launched.
The stun safe plan on the first G-Shock has 10 layers securing the quartz timekeeping module, including a urethane elastic guard, the treated steel case, the solidified mineral glass watch gem, the tempered steel screwed down caseback, and the "gliding module" where the quartz component skims free in a urethane froth support, with the external catches and LCD module joined with adaptable links. The tie of the watch is additionally intended to ensure the module during a fall.
Casio delivered the G-Shock in April 1983, to fill the interest for strong watches. Deals were slow in Japan as individuals favored dress watches. To advance the G-Shock around the world, the American division of Casio delivered a business in which an ice hockey player utilized the DW-5000C as a hockey puck to show the sturdiness of the watch. The business picked up negative exposure and Casio was blamed for bogus promoting. A TV news channel at that point set out to direct live tests on the DW-5000C to check whether it was as extreme and solid as promoted. This elaborate rehashing the activity appeared in the business.
G-Shock Mini are 30% more modest than an ordinary G-Shock and were initially promoted for ladies. Notwithstanding, they were later delivered in unisex variations planned for individuals who have more modest wrists.
On September 1, 2017, Casio commended its 100 millionth shipment of G-Shocks worldwide.
