Take Casio’s formula for making an analog-digital beater watch into a legend in no time flat and you get the original GA2100 “CasiOak”. It’s a watch that mimics the Audemars Piguet Royal Oak for a fraction of the cost. Now, the brand has made a full metal version known as the GMB-2100. In full steel, it turns the watch into a premium-looking timepiece. The tough metal watch also benefits from the CasiOak’s shock absorption layer, as well as a new stainless steel bracelet with a three fold dual button clasp. The handsome dial remains, and functionalities such as solar charging and Bluetooth come standard, too. All three models (steel, grey, copper) have sold out in pre-order, but don’t fret. Regular stock is on its way.
