This mini mechanical marvel deserves a fitting stage. With clean lines, a sleek profile, and delicate hour markers and hands, the new Vacheron Constantin Perpetual Calendar embodies the Patrimony Contemporaine collection's distinctive style. The opaline silver dial showcases a golden moon against a lapis lazuli backdrop. The 41mm 18K pink gold case is water-resistant up to 30 meters and features a sapphire crystal back to reveal Calibre 1120 QP. This watch comes with an alligator leather strap and an 18K pink gold folding clasp.
