Ron Herman has teamed up with Casio G-Shock on the classic GLX-5600, featuring a subdued blue shade finishing an equally understated silhouette. The compact, throwback design is tailor-made for action sports enthusiasts, with Tide & Moon Graph functionality and 200M water resistance for avid surfers. A discrete Ron Herman logo hit, appearing on the lower portion of the watch face, rounds out the details. The piece is available now at Ron Herman locations in Japan.
