Casio G Shock Gravity Master Tactical Watch

Equipped with Twin Sensor capabilities, creating a watch that is perfectly matched to the needs of modern aviators. Continual direction readings can be taken for 20 seconds, during which the second hand points to north, a literal direction indicator is displayed in the upper display, and a direction angle value is displayed in the lower display. Bearing Memory lets you temporarily store and display a direction reading so you can use it as a reference as you take subsequent digital compass readings.
