Mark the 40th anniversary of G-SHOCK with the limited-edition DW-5040PG, a recrystallized and deep-layer hardened stainless steel timepiece developed in honor of the original DW-5000 debut in April 1983. The screw-lock case back, buckle, and band loop all undergo recrystallization and deep-layer hardening processes, while the band and bezel are made of biomass plastics to reduce environmental impact. Engravings of four stars and "PROJECT TEAM 'Tough'" pay tribute to the first G-SHOCK development team, while the 40th logo designed by Eric Haze is on the case back and the lower left button features a star engraving. With features such as world time, stopwatch, countdown timer, and alarms, this timepiece is a perfect combination of style and functionality.
