PATRIMONY PERPETUAL CALENDAR ULTRA-THIN
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 self-winding movement. With its sleek lines embodying
quintessential elegance, this version treats connoisseurs to
unrivalled contemporary refinement.
The 1120 QP calibre developed and crafted by Vacheron
Constantin drives the indications of 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.
Recognised 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 colour is only revealed after ultra-precise firing at very
high temperature (approx. 1000°C), evokes the beauty of life’s
most beautiful nights.
