Duomètre à Quantième Lunaire 40,5mm
case: 18-carat pink gold, sapphire crystal, 1 crown for the date and 1 for winding/time-setting, 1 moon-phase corrector Size: 40.5mm Movement: mechanical manually-wound movement with two distinct mechanisms (Calibre 381 with a 50-hour power reserve), crafted and assembled by hand, comprising 367 parts including 2 independent barrels Functions: hours, minutes, seconds, jumping seconds, date, age and phase of the moon (for the two hemispheres), double power reserve, date corrector Dial: crystalline grained, with pink gold appliques Strap: chocolate-toned alligator leather with 18-carat gold pin buckle Water resistance: 50m
The synchronisation between these two separate mechanisms (hence the name Dual-Wing) is governed by a jumping seconds hand (visible at 6 o’clock) which makes one full rotation in one second, composed of six successive jumps and providing a fascinating show. Two openings on either side harmoniously display the power-reserve indicators revealing the state of the two energy sources. In an ultimate touch of refinement, the twin-type movement structure makes it possible to spread the other indications very clearly over the dial surface. Hours and minutes are shown on the right of the dial, while a symmetrically placed pointer-type date indication on the left side is displayed concentrically with a moon-phase indicator featuring a double hand showing the age of the moon by number of days on the one hand, as well as the state of its phase for the Southern hemisphere on the other. The picture would not be complete without a mention of the device that resets the two seconds hand during time-setting without stopping the oscillations of the balance; as well as the stunning quality of the movement finishing and decorations visible through the sapphire crystal case-back.
