Vacheron Constantin Patrimony Retrograde day-date 4000U/000P-H003 New

Vacheron Constantin Patrimony Retrograde Day-Date reference 4000U/000P-H003 is a masterpiece of haute horology, blending minimalist mid-century design with rare, complex calendar mechanics. Framed in a 42.5mm 950 platinum case that is a sleek 9.7mm thick, the watch is instantly recognizable by its striking sunburst satin-finished salmon-toned dial, a signature aesthetic color combination that Vacheron Constantin reserves strictly for its platinum models. Its standout complications include a dual retrograde display: the numerical date arches across the top half of the dial, while the days of the week span the lower half, both indicated by open-worked, blued steel arrow hands that snap back instantly to their starting positions at the end of each cycle. Visible through the transparent sapphire crystal caseback, the watch is driven by the self-winding, in-house Caliber 2460 R31R7/3, an automatic movement bearing the prestigious Hallmark of Geneva that contains 276 components, operates at 4Hz, and delivers a 40-hour power reserve.
