Take the GMW-B5000 — the original full-metal take on the first-ever G-SHOCK, the DW-5000C — and add plenty of Eric Haze touches for a specially designed metal watch featuring the artist’s work, in ion-plating and laser engraving.
The stainless steel band is ion-plated in black with Haze’s original graphics reproduced in laser-engraved patterns of dots. Small, medium, and large dots combine to create the impression of tonal shading in his characteristic graphic designs splashed across the entire band.
The screw-lock case back, coated in diamond-like carbon (DLC), features a logo designed by Haze to commemorate the 40th anniversary of G-SHOCK.
Press the light button to reveal Haze’s graffiti tag and enjoy the fade-in/fade-out effect.
The watch comes in special packaging adorned with the commemorative anniversary logo designed by the artist himself for a stellar timepiece and incomparable 40th anniversary celebration.
* Due to the screw-lock construction of the case back, the logo and lettering may not match up perfectly with the dial.
