Celebrating G-Shock's 40th anniversary, the limited edition G-shock DW-5040PG-1CR is an ode to the brand's very beginnings. The black resin construction is made with sustainable biomass plastics, while hardened and recrystallized stainless steel material offers a premium look. With a special edition case back designed by Eric Haze, the 40th anniversary G-shock is complete with 200 meters of water resistance, and a legendary shock-resistant design.
