From Vacheron Constantin, presenting the Patrimony (ref. 4010U/000P-B545), a contemporary classic shaped by careful watchmaking know-how. The exterior is thoughtfully executed: crafted in platinum and measuring 42.5 mm in diameter, with a thickness of 9.7 mm, defined by a round silhouette. The caseback is open, and the crystal is sapphire, delivering water resistance to 3000 meters. At a glance, the dial balances texture and clarity: a silver tone, executed in platinum, framed by stick / dot hour markers, and stick hands. At its heart beats a proven engine: the 2460 R31L caliber. Released in a constrained run, appealing to focused collectors. First released in 2016. With considered ergonomics, it feels composed during extended wear. Brushed and polished elements play with light to emphasize crisp geometry. For buyers researching specifications and real-world impressions, this reference stands out for coherent design, dependable mechanics, and lasting relevance within modern horology.
