The Vacheron Constantin Patrimony Bi-Retrograde Ref. 86020/000R-9239 combines the restrained elegance of the Patrimony collection with an unusual pair of retrograde calendar indications. This 2010 example features an 18K pink gold case and silvered dial, creating an elegant setting for the technically distinctive day and date display.
The 42.5 mm 18K pink gold case measures approximately 10.2 mm thick. The silver opaline dial features applied pink gold hour markers and slim hands, while a large retrograde date scale occupies the upper half of the dial and the retrograde day-of-week display is positioned below.
The watch is powered by the automatic Vacheron Constantin Caliber 2460 R31R7, a 27-jewel manufacture movement composed of 283 parts. Operating at 28,800 vibrations per hour, it offers approximately 40 hours of power reserve and provides hours, minutes, retrograde date, and retrograde day-of-week functions.
A sapphire crystal protects the dial, while the transparent sapphire crystal caseback provides a view of the decorated automatic movement. The watch is paired with a brown alligator leather strap and an 18K pink gold folding clasp. Water resistance is rated to 30 meters.
