We mark this anniversary with the GMW-B5000PS — an addition to the line of GMW-B5000 full-metal takes on the very first G-SHOCK, the DW-5000, which debuted 40 years ago in April 1983.

The limited-edition timepiece is clad in recrystallised and deep-layer hardened stainless steel developed with this run in mind. Following recrystallisation 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 DW-5000, 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 crystallises the G-SHOCK 40th anniversary celebration.
