DENSITY ALTITUDE CALCULATOR
Aviator II is predestined above all for all pilots of aircraft driven by one or more propellers. The self- winding mechanical movement indicating hours, minutes and seconds helps reduce the total thickness of the watch down to 11.80 mm, yet it remains water-resistant when immersed up to 50 m. Every pilot, whether flying professionally or for pleasure, will know himself free yet safe with Aviator II strapped on his wrist.
