Information on G-Shock

Casio's G-Shock watch is the fruit of company developers' efforts to manufacture an indestructible watch. After 200 experimental prototypes and two years of structural and parts improvement, the original G-Shock watch was released in 1983.

Structure

• Casio's "Triple 10" design concept gave the first G-Shock watch a 10-year battery life, 10-meter free-fall endurance and 10-bar water resistance. The G-Shock's use of cushioning material, hollow-structured casing and all-directional protective covering have built a foundation for further advancement and a central role in Casio's product line.

Technology

• Following a sales boom in the 1990s, the G-Shock watch began adopting new sensors, new materials for increased durability and solar-powered radio technology. In 2010, the G-Shock watch features a rechargeable battery that converts solar light from panels on the face of the watch into energy. G-Shock watches provide daily self-adjusted time based on American Standard Time information transmitted via radio waves from Fort Collins, Colorado.

2010 Models

• As of 2010, Casio offers 155 different models of the G-Shock watch that come in various colors and styles. G-Shock categories include Classic, Giez, Limited, Master of G and MTG.
