Casio G-Shock GM-S2100 Watches

*GM-S2100BC-1A — Updated October 2023 Color!

About the Watch in short. Go slim, clean and bold with a mid-sized G-SHOCK in a metal-clad octagonal take on the original iconic design.
Forged in stainless steel with rounded hairline finish, the strong bezel says super style all the way. Only the lettering at the top and bottom are engraved, for a simple, one-piece design. The dial, flattened for slimness, is treated with ion plating color and mirrored indexes to add shimmery depth.
