Casio G-Shock Extra Large Series Black Resin Band Watch GA100-1A4 GA-100-1A4

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.
