The Yeslam Aviator II first timepiece the first watch created for and by pilots.Whereas the specific features of the first Aviator model were aligned to jet pilots only, Aviator II is predestined above all for all pilots of aircraft driven by one or more propellers.

Air density is a parameter which varies according to temperature, altitude, atmospheric pressure and air humidity.The lower the air density, the more the engine (propeller) performances are diminished.Under such conditions, the take-off or landing distance can be multiplied by up to a factor of 4. The same applies in flight for the speed and rate of climb, which can find themselves radically reduced.

Exact knowledge of this parameter is therefore essential for obvious safety reasons.

Borrowing the two-directional rotating bezel mechanism from its illustrious predecessor, Aviator II gives the air density in a single manoeuvre. This new application is also covered by an international patent.

Aviator II reproduces the 44 mm-diameter stainless steel case and the bezel is also covered in vulcanised rubber to improve grip.

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.
