Vacheron Constantin 86020 Patrimony Retrograde Day-Date 18K White Gold Silver Dial

The Vacheron Constantin Patrimony Retrograde Day‑Date reference 86020/000G‑9508 is a refined expression of haute horlogerie, introduced in 2010 as the white gold variant of the bi‑retrograde model. Its 42.5 mm 18‑carat white gold case, measuring approximately 10.02 mm thick, frames a serene silver dial with twin retrograde arcs for the day and date—an elegant yet mechanically intricate complication that returns the hands in under a tenth of a second. Powered by the automatic Calibre 2460 R31R7 with 27 jewels, a 40‑hour power reserve, and crowned by the Poinçon de Genève seal, this timepiece embodies both technical excellence and aesthetic restraint. The open sapphire caseback reveals the beautifully finished movement and its 22‑carat gold rotor, a hallmark of Vacheron’s dedication to fine finishing. With a modest 30 m water resistance and presented on a black alligator strap with deployant clasp, the watch balances daily practicality with dress‑watch elegance. Though not a limited edition, its complexity and discreet elegance make it a collector’s favorite within the Patrimony line, offering both horological substance and timeless style.
