G-Shock • GA100-1A1 • Men's Watch
Living up to G-Shock’s reputation for big case designs, comes a revolution in case size with the introduction of the X-Large GA100-1A1. 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. The GA100-1A1 has become a staple in the ever expanding G-Shock family.
