This new model GA1000-1A, is the first in the GRAVITYMASTER lineup to be equipped with digital compass capabilities, creating a watch that is perfectly matched to the needs of the modern aviator, both in terms of function and appearance. Pressing the 9 o’clock button in any mode immediately goes to the Digital Compass Mode, and a button at 8 o’clock returns to the mode you were in before the Digital Compass Mode. 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. Other features include temperature measurement, large numerals, and thick hands for easy reading. A coating on the tip of the second hand and minute markers reacts with the black light illumination of the watch for easy reading in the dark.
Shock Resistant construction protects against impact and vibration.
