Introducing Vacheron Constantin Traditionnelle (ref. 80172/000P-9505), a distinctive model that balances proportion, precision, and presence. On the wrist, the case feels purposeful: crafted in platinum and measuring 44 mm in diameter, with a thickness of 13.54 mm, defined by a round silhouette. The caseback is open, and the crystal is sapphire. Visually, the face is where character emerges: a grey tone, framed by stick / dot hour markers, and dauphine hands. Mechanically, the watch prioritizes accuracy: the 2755 caliber. First released in 2010. The silhouette offers presence without excess, lending confidence in a range of situations. Finishing showcases disciplined attention to detail across facets, edges, and surfaces. For buyers researching specifications and real-world impressions, this reference stands out for coherent design, dependable mechanics, and lasting relevance within modern horology.
