Experience the craft of Vacheron Constantin in the Traditionnelle (ref. 87172/000R-B167), a contemporary classic shaped by careful watchmaking know-how. The exterior is thoughtfully executed: crafted in pink gold and measuring 38 mm in diameter, with a thickness of 8.02 mm, defined by a round silhouette, paired with a gem-set bezel. 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 with guilloche finish, executed in pink gold, framed by stick / dot hour markers, and dauphine hands. At its heart beats a proven engine: the 2455 caliber. Initial production year: 2007. 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.
