Vacheron Constantin Patrimony Moon Phase Retrograde Date

The Vacheron Constantin Patrimony Moon Phase Retrograde Date extends the Patrimony series with another timeless and classic masterpiece from the oldest Swiss watchmaker. We already liked the Patrimony Perpetual Calendar with moon phase and the Patrimony Retrograde Day-Date, both in pink or white gold. And this is the third model with appealing complications.

Like the other two models, the Patrimony Moon Phase Retrograde Date comes in pink or white gold. Its case measures 42.5 millimeters with a transparent case back. So you will have a look at Vacheron Constantins 2460 R31L caliber, a self-winding movement with a power-reserve of 40 hours.

Adjust the Vacheron Constantin Patrimony Moon Phase Retrograde Date once every 122 years the keep the moon phase accurate

The retrograde date is just under de 12 o’clock position, just above Vacherons logo and its signature Maltese cross. The moon phase is just above 6 o’clock and has two remarkable characteristics. At first the moon has a color that matches the color of the case. Second, the moon phase only needs a one-day correction once every 122 years. An extreme accuracy if you consider that the real lunar cycle around the Earth lasts exactly 29 days, 12 hours and 45 minutes. The silvered opaline dial features tapered applied hour-markers in pink or white gold as well as a circular “pearl” minute-track.

All complications and indications can be adjusted from the crown, including the moon phase. In the first position of the crown, the movement can be hand-wound. In the second, clockwise rotation sets the date, and counter-clockwise sets the moon phase. In the third, you set the time.
