Vacheron Constantin Patrimony Perpetual Calendar Ultra-Thin, Pink Gold Model with Midnight Blue Dial

Vacheron Constantin expands their Patrimony collection by introducing a new perpetual calendar ultra-thin watch in pink gold with a midnight blue dial.

The self-winding 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. The moon phase display, adorned in champlevé enamel, evokes the beauty of life’s most beautiful nights.

The perpetual calendar complication requires miniaturisation prowess in that the movement must be mechanically adjusted to deal with calendar irregularities. This miniaturisation has been pushed to the limit in order to create an ultra-thin perpetual calendar, with Vacheron Constantin’s Calibre 1120 QP measuring a mere 4.05 mm thick. This feat of engineering with its openwork Maltese cross-shaped oscillating weight comprises no less than 276 components, finished in accordance with the highest standards of Haute Horlogerie.

The exceptional level of finishing of this movement can be admired through the transparent sapphire crystal caseback of the watch. Finally, the steady beating of its heart at a rate of 2.75 Hz (19,800 vibrations per hour) ensures the precision of the movement as well as its 40-hour power reserve.

Introduced with a pink gold case that makes a perfect match with the sunburst satin-finished blue shade of the dial, and equipped with a folding clasp, this watch naturally conveys the personality of its owner: a timelessly elegant aesthete who matches his appearance with the dark blue of the alligator leather strap, of which the back is also lined with the same leather in an ultimate touch of refinement.
