G-Shock watches hardly need an introduction. Their appeal is obvious; they are one of the few products in the world that can call itself battle-tested, and mean it literally. G-Shock watches haven’t adopted a rugged aesthetic as a marketing angle, they really have been, and continue to be used by deep sea divers, special forces soldiers, and astronauts. 

G-Shock marks their 40th anniversary with the GMWB5000PS — a full-metal take on the very first G-SHOCK, the DW5000, which debuted 40 years ago in April 1983. The limited-edition timepiece is clad in recrystallized and deep-layer hardened stainless steel developed with this run in mind.

Following recrystallization and deep-layer hardening, the bezel and band are treated with titanium carbide (TiC) coating and the screw-lock case back with DLC coating for a bold, radiant look. In a special nod to the DW5000, the dial features the phrase “SINCE 1983.”The case back is engraved with the Eric Haze-designed 40th logo, and the lower left button is engraved with a star, for a timepiece that crystallizes the G-SHOCK 40th anniversary celebration.
