PRIMUS

THE WORLD'S UNIQUE TRIPLE AXIS TOURBILLON WRISTWATCH WITH JEWEL BEARINGS ONLY

PRIMUS, the first BEXEI tourbillon wrist watch has an extremely complicated and unique movement. Respecting traditional watchmaking Aaron Becsei invented the three axis tourbillion movement where the 3rd (external) cage's unique form provides the possibility of using jewel bearings everywhere - instead of ball-bearings. This is a unique solution at this size and level of complication. (PATENTED) As all Bexei watches the parts of Primus were made by Aaron Becsei at his workshop (including the gears, the wheels, the pinions, the screws and also the case, buckle, crown, dial and the hands). All the parts with the top level hand made finishing as independent jewels.
