Our take on the Casio G-Shock 2100 Utility Black Digital Quartz Watch

The GA-2100 is Casio's slim octagonal G-Shock, mixing analog hands with a small digital display. It is the thinnest G-Shock of its line at about 11mm, so it slips under a sleeve where a chunky square G-Shock will not. Carbon Core Guard resin makes it light and shock-resistant, and 200m water resistance covers swimming. Owners like the stealthy black look and the price-to-toughness ratio; the common complaints are the dim LED light and the small digital window.

A nice looking watch from Casio which has a black strap. The glass is very durable since it's made from mineral.
