The perpetual calendar is one of the most challenging complications in watchmaking. This complex, intelligent mechanism guarantees that the date, weekday and month are always shown accurately – even automatically accounting for leap years – without the need for any manual correction for more than a century. This masterpiece of watchmaking has been redefined with the innovative manufacture movement Calibre 36, which sets new standards for precision, stability, running time and aesthetics.

The slim bezel offers a generous view of the lacquered dial with a delicate silver grain, the laser-cut and black galvanised indexes, and the matching railroad chapter ring. The small minute markers are printed in a vibrant red. The Panorama Date, the weekday and the month windows are beautifully accentuated by frames in the style of a passe-partout. A separate display below 12 o’clock depicts the leap years; its small hand moves along a scale from 1 to 4 in an anti-clockwise direction.
