G-Shock GA100-1A4Living 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.
