Perpetual calendar ultra-thin 4305T/000G-B948
Introduced by the Republic and Canton of Geneva in 1886 as the ultimate standard in excellence and an emblem of Geneva’s fine watchmaking expertise, the Poinçon de Genève or Hallmark of Geneva, is synonymous with provenance, quality craftsmanship and reliability.
Greatly appreciated by connoisseurs, the 4.05 mm in-house Calibre 1120 QP gives life to a new Traditionnelle perpetual calendar ultra-thin designed for women's wrists. This 36.5 mm-diameter model reflects Vacheron Constantin's grand tradition of horological complications, notably interpreted through ultra-thin versions. Its 18K white gold case bears the identity codes of the Traditionnelle collection featuring meticulous handcrafted finishing. Its gem-set bezel and its dial graced with delicately shimmering mother-of-pearl have been meticulously designed to ensure optimum legibility of the calendar indications.
Excellence through details
This new feminine timepiece belongs to the Traditionnelle collection, a line imbued with Geneva's grand watchmaking heritage and designed to suit both simple hour-minute watches and those equipped with sophisticated complications. The Traditionnelle perpetual calendar ultra-thin seeks to fulfil women’s desire for watches with mechanical complications.
The Maison's Calibre 1120 QP elegantly plays on distinctive aspects of the Gregorian calendar. Days, dates, months and years are displayed on a four-year cycle, including a leap-year indication, that requires no correction before 2100. A moon-phase indicator at 6 o'clock complements the calendar. The movement stands also out for its slimness: only 4.05 mm deep, it is housed in an 8.43 mm-thick case with a 36.5 mm diameter, ensuring perfect visual harmony.
For the first time in the collection, this Traditionnelle perpetual calendar ultra-thin watch is equipped with an interchangeable strap that can be fitted at the touch of a push-button and without any need for tools. Each model comes with an alligator leather strap – grey blue or rosy beige – secured by a white or pink gold pin buckle set with 17 round-cut diamonds.
