At the SIHH last January, Vacheron Constantin introduced a midnight blue color in a trio of Patrimony models and the new perpetual calendar with satin-finish blue dial is part of this lineage. It offers aesthetes a more contemporary alternative to the existing ultra-thin Patrimony perpetual calendar versions, in pink gold with white or anthracite dial, or belonging to the Excellence Platine line.
Vacheron Constantin's first perpetual calendar dates back to an 1883 pocket watch. Since then, the Manufacture has constantly improved and miniaturized its movements. Concentrated within a thickness of just 4.05mm, the 1120 QP in-house caliber 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 perpetual calendar takes account of the leap-year cycle, with its 31, 30 or 28-day months and the quadrennial return of February 29th, and can cope with all the vagaries of the calendar without any corrections until March 1st 2100. In a final pleasing touch, the moon phase display, adorned in champlevé enamel, evokes the beauty of life’s most beautiful nights.
The 1120 QP caliber displays its openwork Maltese cross-shaped oscillating weight and exceptional level of finishing through the transparent sapphire crystal caseback of the watch. Crafted in 18K 5N pink gold, the case measures 41 mm in diameter and only 8.9 mm in thickness. The pink gold makes a perfect match with the sunburst satin-finished blue shade of the dial. The dark blue alligator leather strap is lined with the same leather in an ultimate touch of refinement, and equipped with a pink gold folding clasp.
