The Patrimony collection reflects the watchmaking expertise of Vacheron Constantin. With the Patrimony Moon Phase Retrograde Date, a timelessly understated round case housing an original self-winding caliber powering a high-precision moon indication requiring no corrections for 122 years, combined with a retrograde date display. A transparent case back reveals the 2460 R31L movement and its 22K gold oscillating weight adorned with the Maison’s signature Maltese cross motif, reflects absolute mastery of the watchmaking art and traditional skills.
