Casio Men's G-Shock Black Resin Watch GA100-1A1

For 25 years Casio G-Shock digital watches are the ultimate tough watch. Providing durable, waterproof men’s digital watches for every activity. 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. Living up to G-Shock's reputation for big case designs, comes a revolution in case size with the introduction of the X-Large G.

Living up to G-Shock’s reputation for big case designs, comes a revolution in case size with the introduction of the X-Large G. This Ana-Digi, “three-eyed” monster measure in at a whopping 55 x 51.2 x 16.9mm size, with an attention to detail, that is second to none. Large anti-skid buttons provide easy operation, embossed indexes gives a 3-D look and a rivet bezel design adds strength to its overall appearance.
