Casio

This new MUDMAN model is the first one to be equipped with a direction sensor and thermo sensor that help you keep your bearings whenever you adventure into parts unknown. The touch of a button goes directly into the Compass Mode from any other mode. A Moon Phase graph gives you an idea of whether the nighttime hours will be dark or light. A declination function even makes it possible to adjust the watch's magnetic north direction reading so it indicates true north. All of this plus Tough Solar to keep everything working, and total shock and mud resistance to keep everything well-protected.
