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 circles imitating 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 batontype hands are made of the same metal, blued for the date pointer for enhanced readability.

The transparent sapphire caseback provides a chance to admire this 275-part movement, notably the circular-grained surface of its mainplate and its openworked 22-carat gold oscillating weight inspired by Vacheron Constantin’s Maltese cross emblem.
The moon phases are displayed through an aperture at 6 o’clock, graduated from 0 to 29½, 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.
