Casio will soon release an updated version of its GA-2100 G-Shock but with a metal bezel that makes it, in our eyes, a really cool finish.

TheCasioG-Shock GM-2100 has an octagonal design (a popular shape these days, considering how many people you see with similarly-angular Ray-Bans on). It follows a long tradition of G-Shock designs, even dating back to the original DW-5000C, yet with a slim profile and digital-analogue combination.

Its forged metal bezel is crafted through a multi-step process, ending with a round hairline finish applied to the top surface. A mirror polish to the sides adds a metallic gleam.

There will me multiple options available, in black (GM-2100-1A), navy blue (GM-2100N-2A), green (GM-2100B-3A) and red (GM-2100B-4A). Each carry the usual G-Shock shock resistance and waterproofing to 200 metres.
