Tokyo, March 15, 2023 — Casio Computer Co., Ltd. announced today the release of the newest additions to its series of shock-resistant G-SHOCK Recrystallized series designed to celebrate the 40th anniversary of the G-SHOCK brand. The GMW-B5000PS and GMW-B5000PG are made even tougher, employing a deep-layer hardening process*1 on stainless steel.
*1 This process creates a hard layer by infusing gas into the surface of the steel, hardening the material itself rather than coating it to harden the outside.
The GMW-B5000PS and GMW-B5000PG are based on the full-metal GMW-B5000D, which faithfully reproduces the iconic shape of the very first G-SHOCK, the DW-5000C. Both of these 40th anniversary models employ extremely hard stainless steel for exterior components such as the bezel and band.
With this latest advance in the continuous G-SHOCK evolution that began back in 1983, Casio has developed a deep-layer hardening process specifically for stainless steel, achieving a material that is approximately three times harder than ordinary stainless steel. Recrystallization adds a design element, with the stainless steel heat-treated and recrystallized to create crystalline patterns against a matte texture, giving the rugged appearance of fine metal fragments scattered across the surface. Each individual component features a unique crystalline grain, delivering subtle differences in pattern, color and luster for each timepiece.
The silver GMW-B5000PS and gold ion-plated GMW-B5000PG both incorporate special features — the 40th anniversary logo on the case back, the phrase “SINCE 1983” on the dial, and a star on the Mode button on the lower left side of the case.
Casio also announced today the release of the DW-5040PG, which features a dial engraved with the words “PROJECT TEAM ‘Tough,’” the name of the team that worked to develop the very first G-SHOCK. For this reissue of the original G-SHOCK design, the deep-layer hardening process is applied to the case back, buckle, band loop, and other metal components. Biomass plastics are used in the bezel and band.
