Vacheron Constantin Traditionnelle Twin Beat Perpetual Calendar

The Traditionnelle Twin Beat Perpetual Calendar (ref. 3200T/000P-H167) is part of Vacheron Constantin's Traditionnelle collection. The 42mm round case is made of platinum with a sapphire crystal and a display back, paired with a grey guilloché dial finished by hand. It houses the manual-winding calibre 3610 QP, a perpetual calendar movement carrying the Poinçon de Genève hallmark, displaying month, year, date and power reserve, with a maximum power reserve of 1680 hours and water resistance of 30 metres. The Hallmark of Geneva, established by the Republic and Canton of Geneva in 1886, certifies watchmaking standards of quality and craftsmanship.
