Frederique Constant’s Perpetual Calendar Tourbillon Manufacture contributes to the quest for ultimate precision. The primary function being to counterbalance the errors due to the effect of the Earth’s gravity on a movement in a vertical position. The titular mechanism of the timepieces is the new automatic FC-975 in-house movement.

This grand complication bears simultaneously: a silicone escapement wheel and anchor, a smart weight balance wheel, and a Tourbillon cage. These timepieces are impressive in horological terms as the Tourbillon has been developed in an industrialized process to the last detail.

Frederique Constant patented the perfectly balanced cage composed of 80 components all produced with a precision of 1-2 micron (0.001-0.002 mm) by the CNC machine in the Manufacture’s ateliers. In order to achieve the highest degree of precision, small weights are added in the Tourbillon’s cage to obtain a perfect balance.
