Vacheron Constantin Patrimony Minute Repeater Perpetual Calendar

About this reference

The Vacheron Constantin Reference 30020 was produced between approximately 1992 and 2005, serving as a successor to the 30010. Collectors value this reference for its combination of a minute repeater and a perpetual calendar within a 37mm platinum case. It houses the manual-wind Calibre 1755, a movement measuring only 3.3mm thick, which was developed during the brand's transition toward modern high-complication manufacturing. The dial features a traditional four-subdial layout with a moon phase at 6 o'clock and a leap year indicator. Production was limited, with estimates suggesting approximately 200 units were made across all metals, making the platinum version particularly scarce. On the secondary market, this reference typically commands prices in the mid-to-high six-figure range, often between $250,000 and $450,000 depending on provenance. A notable auction result occurred in 2019 when a platinum example sold for approximately $337,000.
