Franck Muller Fast Tourbillon

This meticulously engineered timepiece clearly reflects the expertise of the Research and Development team at Franck Muller and houses the world’s fastest tourbillon escapement.

Powered by four barrels, the tourbillon cage makes one full rotation every 5 seconds on a ceramic ball bearing. This translates to 12 rotations per minute, making it 12 times faster than the average tourbillons available in the market today.

The rotating frame is characterized by the patented FM escapement with a fixed escapement wheel and reversed anchor and balance wheel. The entirely in-housemanufactured ‘Breguet hairspring’ further boosts this technical marvel.

The movement, completely designed and conceptualized in-house, makes 21’600 vibrations per hour and offers a power reserve of 50 hours. It is finished with a fine combination of engraving, rhodium plating, graining and hand-beveling.

The Franck Muller Fast Tourbillon™ is available in the 18-carat gold or black DLC Cintrée Curvex™ case.
