CASIO G-SHOCK 40th Anniversary Adventurer's Stone GM-5640GEM-1JR

Chart your own course with a G-SHOCK 40th Anniversary Adventurer's Stone limited-edition timepiece.

Join us in celebrating the G-SHOCK 40th by choosing one of these spectacular metal-clad watches, which are inspired by the stones adventurers have used to navigate since ancient times.

The special colors of the minerals ancient seafarers used to find their way are reproduced in these watch designs with forging, ion plating, and masking processes, giving each metal bezel a one-of-a-kind look. The bands are made with colored or translucent resin and are uniquely textured with hot-stamping and Garal color molding techniques.

These limited-edition timepieces celebrate the G-SHOCK 40th through and through: the phrase "SINCE 1983" appears on the dial; the Eric Haze-designed 40th logo is engraved on the case back, and there are four stars for 40 on the band loop.
