Carry on the G-SHOCK legacy — go traditional with the original dial colours of the DW-5000C, the very first G-SHOCK, now in a full-metal watch.
The classic G-SHOCK colours are on full display with faithful reproductions of G-SHOCK red, representing the passion to take on challenges; blue, symbolising excellent water resistance; and yellow, signifying outstanding shock resistance.
Crafting a stainless-steel bezel of this depth and dimension requires a time-consuming forging, cutting, and polishing process. The bezel top is finished beautifully with a hairline treatment and the beveled edges with a mirror finish for maximum textural beauty.
Achieving a full-metal timepiece with the same original G-SHOCK shock-resistant structure is no easy feat. We installed buffering components made of fine resin between the stainless-steel bezel and case and employed a three-pronged lug for the band connection to disperse shocks to the connecting pipes. The stainless-steel case also features the same screw-lock construction as the original to ensure a tight seal.
Dimpling applied to metal band pieces reproduces the look of the resin band design of the very first G-SHOCK. And the fact that the watch is crafted at Yamagata Casio, the “mother factory” where the first-ever G-SHOCK was made, brings the whole design full circle.
