Elegant, clear and eye-catching: the medium-sized G-SHOCK in the octagonal metal version of the iconic original design.
The robust stainless steel bezel with rounded hairline finish is a real eye-catcher. Only the top and bottom lettering is engraved, for a simple, uniform design. The dial, flattened for an elegant look, is treated with ion plating and features mirrored indices that add shimmering depth.
Which look to choose: rose gold bezel on a black strap, dark gray on a black strap, or silver on a green strap.
