From the men's Casio Mudman Collection, the black ion-plated resin style features a 46.0mm digital dial, a 1/100-second stopwatch capable of measuring continuous elapsed time for up to 1,000 hours and a pre-programmed calendar. A rugged design and sleek casing create a classic G-shock look with an industrial twist. It can hold a charge for up to 26 months in complete darkness thanks to the model's power saving mode.
