Housed in a round 40mm case crafted from 18K 5N pink gold — a warm, rose-toned alloy — the Patrimony measures just 8.55mm thick, lending it a slim, wrist-friendly profile. The crown is finished in matching 18K 5N pink gold, and the metal dial is protected by a transparent sapphire caseback that allows a view of the movement within.
The watch is secured by a black alligator Mississippiensis strap fastened with an ardillon buckle in 18K 5N pink gold, maintaining a consistent material story throughout. Water resistance is rated to 3 bar.
This listing includes the complete set: the Vacheron Constantin box and Vacheron Constantin papers, reference 85180/000R-9166.
