Measuring 38mm in diameter and 8.02mm in thickness, the Traditionnelle reference 87172/000R-B167 is fashioned entirely in 18K 5N pink gold — from the round case and crown through to the dial itself. A transparent sapphire caseback offers a clear view of the movement within, while water resistance is rated to 3 bar.
The watch rides on a dark brown alligator Mississippiensis strap, secured by an 18K 5N pink gold ardillon buckle. This cohesive use of warm pink gold throughout the case, dial, and hardware gives the piece a quietly considered, unified character.
Reference 87172/000R-B167 sits within Vacheron Constantin's Traditionnelle collection, a line long associated with classical proportions and refined finishing — making this rose gold example a compelling expression of the house's enduring approach to dress watchmaking.
