These new additions to the GRAVITYMASTER lineup are 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, while the 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. A bearing memory can be used to store a bearing reading that you can recall for later reference when you need it. 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. Neon Illuminator and Neo-Brite luminous hands Neon Illuminator features a built-in black light that illuminates the second hand and gradations when activated. The hour and minute hands and insets absorb light rapidly and continue to glow in the dark for several hours afterwards.
