Following recrystallization and deep-layer hardening, the bezel and band are treated with gold ion plating 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.

*The stainless steel is processed into components and then recrystallized, yielding unique differences in crystalline grain. This makes the pattern, color tone, and luster differ subtly from part to part.
