Vacheron Constantin Patrimony Perpetual Calendar – Moscow Boutique Edition

To celebrate the opening of its new Moscow Boutique, Vacheron Constantin presents a Patrimony equipped with a sophisticated complication: the perpetual calendar.

Housing the legendary Calibre 1120 QP, an ultra-thin mechanical selfwinding movement, the Patrimony perpetual calendar reveals the inherent elegance and finesse of Vacheron Constantin. This timepiece issued in a 30-piece limited edition.

Issued in a 30-piece limited edition, the Patrimony Perpetual Calendar Moscow Boutique Edition meets the demanding requirements of the Hallmark of Geneva – the highest benchmark in the field of Haute Horlogerie testifying to the quality, craftsmanship and reliability of an exceptional timepiece produced on Genevan territory. It pays tribute to longstanding watchmaking tradition expertise, acquired over a period of almost 260 years by a Manufacture that set out to conquer Russia at a very early stage in its history.

The Patrimony Perpetual Calendar Moscow Boutique model is equipped with the legendary Calibre 1120 QP, acknowledged by connoisseurs as one of the most iconic perpetual calendar movements.

This timepiece will be able to keep track of all the vagaries of the calendar and require no correction whatsoever until March 1st2100. Unlike simple calendar mechanisms that require manual correction after each month with less than 31 days, the perpetual calendar takes account of the leap-year cycle with its months of 31, 30 or 28 days, and the quadrennial return of February 29th.

Since the movement must be mechanically adjusted to take account of calendar irregularities, this sophisticated function calls for considerable prowess in terms of miniaturisation. An indispensable prerequisite for integrating the calendar functions, this miniaturisation was pushed to the limit in order to create an ultra-thin perpetual calendar movement measuring a mere 4.05 mm thick.

This mechanical hand-wound movement is equipped with an oscillating weight featuring the particularly meticulous finishing that is the signature of Haute Horlogerie.

Beating at a frequency of 2.75 Hz (19,800 vibrations per hour), it has an approximately 40-hour power reserve. Calibre 1120 QP drives indications of the hours, minutes and a perpetual calendar displaying the day of the week, the date, the month, the leap year on a 48-month subdial, as well as the moon phase.

Such a miniaturised mechanical marvel deserved a truly worthy stage-setting. Characterised by taut curves, a sleek profile, slender trapeze-shaped hour-markers, baton hands, a cambered dial and a minute track beaded with gold cabochons, the new Patrimony Perpetual Calendar Moscow Boutique model by Vacheron Constantin features all the distinctive characteristics of the Patrimony collection.

Beneath its opaline black dial, the lunar disc portrays a golden moon set against a lapis lazuli sky. The 41 mm-diameter 18K white gold case is water-resistant to 30 metres and fitted with a sapphire crystal back revealing Calibre 1120 QP. This timepiece is equipped with an alligator leather strap secured by an 18K white gold folding clasp.

In an ultimate touch of elegance and refinement, the Patrimony Perpetual Calendar Moscow Boutique model comes with a pair of 18-carat white gold and onyx cufflinks matching the Vacheron Constantin timepiece.
