Casio G-Shock GRAVITYMASTER Twin Sensor GA-1000-1A GA1000-1A Men’s Watch

This is the first GRAVITYMASTER ever to come out. Equipped with a digital compass, it is the perfect watch for the modern aviator, for it also allows a continual direction reading, indicating both literal direction and direction angle value. The results can be stored in the bearing memory. It also reads temperature and there’s a black-LED illumination that comes quite handy in the dark.
