The Secret Signature

The secret signature on sand-blasted dial of the Patrimony moon phase retrograde date watch is the inscription «Pt 950» between 4 and 5 o’clock. The moon-phase disc, which can be admired through an aperture at 6 o’clock, is also in platinum with a polished surface on the stars and a grained texture for the moon circlesimitating the visible irregularities of the lunar surface. The dial is slightly convex around its circumference and punctuated by applied 18-carat white gold hour-markers, appearing at intervals around a likewise white gold “pearl” minute-track. The baton- type hands are made of the same metal, blued for the date pointer for enhanced readability. 

Excellence Platine

The moon phases are displayed through an aperture at 6 o’clock, graduated from 0 to 291⁄2, serving to count off the number of days elapsed since the last new moon. This horological complication, known as the age of the moon, corresponds to the actual cycle of this heavenly body, which rotates around the Earth in exactly 29 days, 12 hours and 45 minutes. The precision moon phases mechanism requires a one-day correction only once every 122 years. 

The second complication – a retrograde date indication by means of the central hand – occupies the upper part of the dial. To ensure user friendliness, all operations are performed via the crown: winding, date correction, moon-phase adjustment and time-setting. 

Excellence Platine

The new Vacheron Constantin Patrimony moon phase retrograde date Collection Excellence Platine is a limited edition of only 50 pieces and available exclusively at Vacheron Constantin boutiques at a price of € 72.500.
