An emblematic model from the Patrimony collection is adopting the midnight blue shade specially created for the line. The Patrimony perpetual calendar ultra-thin watch beats to the rhythm of the legendary 1120 QP calibre, an ultra-thin automatic movement. Introduced with an 18K 5N pink gold case measuring 41 mm in diameter and less than 9 mm in thickness, the warm hue of the case is a perfect match for the sunburst satin-finished blue shade of the dial. With its sleek lines embodying quintessential elegance, this version treats connoisseurs to unrivaled contemporary refinement.

The new Patrimony Perpetual Calendar Ultra-Thin with midnight blue dial indicates the hours, minutes, moon phase at 6 o'clock and perpetual calendar with day of the week in a counter at 9 o'clock, date in a counter at 3 o'clock, as well as month and leap year on 48-month counters at 12 o'clock. Recognized by connoisseurs as one of the most iconic perpetual calendars on the market, it can cope with all the vagaries of the calendar without any corrections until March 1st 2100. Unlike simple calendars that require manual adjustment after each month of less than 31 days, the perpetual calendar takes account of the leap-year cycle, with its 31, 30 or 28-day months and the quadrennial return of February 29th.

In a final pleasing touch, the moon phase display, adorned in champlevé enamel whose color is only revealed after ultra-precise firing at very high temperature, evokes the beauty of life’s most beautiful nights.

The Movement

The Patrimony Perpetual Calendar Ultra-Thin Blue dial is powered by the in-house calibre 1120 QP fully developed and crafted by Vacheron Constantin. This movement measuring a mere 4.05 mm thick is a feat of horological engineering with its skeletonized Maltese cross-shaped oscillating weight, its 276 components, and finished in accordance with the highest standards of Haute Horlogerie. Beating at a frequency of 19,800 vph, this precise movement provides a power reserve of 40 hours when fully wound.
