1815 Chronograph

The sleek, elegant looks of the watch contrast with the intricacy of the calibre L951.5 chronograph movement with column-wheel control and a stepped pinion for the precisely jumping minute counter. One of the highlights among the numerous technical features is the flyback function, a device found only in very few chronographs. With one single push piece, the 1815 CHRONOGRAPH can be stopped and reset in the middle of a time measurement. And a new measurement is started as soon as the push piece is released again.

The sapphire-crystal caseback reveals one of the technically most exquisite and at the same time most beautiful chronograph mechanisms ever made. It showcases most of the technical and artisanal details, including the stepped pinion for the precisely jumping minute counter, the column wheel that controls the chronograph functions, and the precision beat adjustment system with its whiplash spring on the hand-engraved balance cock. This is state-of-the-art chronography at its absolute best.
