G-Shock GA-100MB Classic X-Large Digital Matte Black Green
G-Shock is dedicated to the ongoing pursuit of further advancement of the Classic G-Shock watch, considering every possible option to improve upon the product. G-Shock Classic Watches are a reflection of this pursuit in its purest sense. Their designs reflect a deeper meaning than the usual superficial styling. These are smart designs born form the pursuit of pure functionality.
G-Shock is the ultimate tough watch. It was born from a developer’s dream of “creating a watch that never breaks.” Guided by a “Triple 10” development concept, the design teams sought a watch with 10-meter free-fall endurance, 10-bar water resistance and a 10-year battery life.
At a time when it was commonly believed that watches were breakable items, G-Shock’s development represented a challenge to common sense. The number of experimental prototypes built for endurance testing reached over 200. And the structural development and parts improvement took approximately two years. After a long, hard process of trial and error, G-Shock was finally launched. A shock resistant structure that overturned conventional thinking about watches was realized thorough breakthrough thinking, including the ideas of a hollow- structured case, all-directional protective covering and the use of cushioning material to protect critical parts.
These were the fruits of technological development that insisted on “toughness” and a revolution in watch design. Since its launched, G-Shock has continued to evolve for 25 long years, carrying on the toughness of spirit and uncompromising passion that led its developers to persist in their unshakable belief.

Button guard that protects the module from direct shocks
Our case shapes are designed in such a way to make sure that the buttons are never struck directly if the watch is dropped, no matter what the angle.
Intelligent Timing
GShock watches employ intelligent, LSI-based electronic technologies to achieve unsurpassed precision and to provide a wide range of features and functions which no conventional mechanical watch can match.
