Vacheron Constantin Patrimony 31 Day Retrograde
Concept & History
The Reference 47245 marks a significant phase in haute horlogerie, during which Vacheron Constantin combined complex calendar displays with asymmetrical dial designs. The design draws on historical design approaches and translates them into a functional retrograde complication. Collectors appreciate this series for its minimalist design, which discreetly houses the highly complex mechanics. This “New Old Stock” example offers a rare opportunity to examine an unworn watch from this production era in immaculate condition.
Caliber & Technology
The model is powered by the Caliber 1126/1, an automatic movement with a 38-hour power reserve and elaborate finishing. The winding rotor features a solid gold segment to optimize winding efficiency. A sophisticated lever mechanism controls the eponymous retrograde date display, which instantly jumps back at the end of the month, while a coaxial display indicates the day of the week. The movement’s architecture features Côtes de Genève on the bridges and meticulously executed beveling on the edges, underscoring the technical sophistication of the design.
Case & Material
The case measures 37 mm in diameter and is crafted from 18k white gold. Typical of this reference series are the flowing flanks and the striking, teardrop-shaped lugs, which visually elongate the case. A stepped sapphire crystal case back offers a view of the finished movement. A modest case height and water resistance of 3 ATM make this model an exclusive dress watch with a highly complex inner workings.
Aesthetics & Readability
The silver dial features a delicate guilloché pattern in the center, upon which applied hour markers and Roman numerals are set. To complement the 18k white gold case, the slender hands and hour markers are finished in a clean silver or steel tone. The upper half of the dial is dominated by the 31-day scale, whose arrow-shaped hand indicates the date. A recessed subdial at six o’clock displays the day of the week. This ensures clear readability of the complex information without disrupting the harmonious symmetry.
