Franck Muller Perpetual Calendar Chronograph Bi-Retro

Perfectly combining ancestral tradition with technique, the Perpetual Calendar watch complication by Franck Muller displays day, date, month, leap years and the moon phase, and it needs no correction until the year 2100.

A multi-complication model in the Franck Muller’s Perpetual Calendars line, the Perpetual Calendar Chronograph Bi-Retro watch features a perpetual calendar, a chronograph and many retrograde indications. Attention to detail and sense of perfection are perfectly demonstrated in these beautiful timepieces, thanks to their hand-crafted movements and breath-taking dial.

This large watchmaking complication is available in the Round Classics versions, the emblematic Cintrée Curvex™ and in the Long Island line.


Its sun-lacquered guilloché dial, a feature of the brand, is enhanced with directive numerals which have turned Franck Muller watches into instantly-recognisable timepieces.
