Uniqueness

The real highlight of the watch is a Swiss automatic movement Eterna 3901A with a specially customized Biatec propeller rotor inspired by the Vought F4U Corsair aircraft.

Big diamond crown

Big diamond crown with Biatec logo remains us old days when pilots could easily wind or adjust their watches while wearing gloves. The lugs of the watch are also a reminder of the legendary design of the Corsair’s wings.
