Casio G-Shock Men's GA100-1A1 Analog / Digital Watch (Color: Black)



Living up to G-Shocks 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.
