From G-SHOCK, the watch brand that is constantly setting new standards for timekeeping toughness, comes the GA100-1A1 analogue model. 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 measures in at a whopping 55 x 51.2 x 16.9mm size, with an attention to detail that is second to none. Large anti-slip buttons provide easy operation, embossed indexes gives a 3-D look and a rivet bezel design adds strength to its overall appearance. 1/1000-second stopwatch, velocity indicator, World Time, 5 alarms and much more provides these models with unmatched function and performance.
