A platinum Vacheron Constantin Perpetual Calendar, Ref. 43031/3 - rarer than its yellow gold counterpart - featuring a factory‑set diamond bezel that lends a restrained opulence to the watch. The opaline dial is smooth, with three gently recessed subdials charting the day, date, month, and leap year, above a lapis lazuli moon phase at 6 o’clock. The self‑winding calibre lies within a 36mm case framed by the stepped diamond‑set bezel. Accompanied by a matching platinum VC tang buckle, this 1990s reference illustrates the discreet elegance of Vacheron Constantin’s complicated watchmaking.
