Measuring 40mm in diameter and 8.55mm thick, the Patrimony's round case and crown are both rendered in 18K 5N pink gold, giving the watch a warm, coherent tone from every angle. A sapphire-crystal caseback opens a view through to the movement within, while the case maintains a water resistance of 3 bar.
The blue metal dial lends a cool contrast to the rose gold case, a pairing that defines the Patrimony's quietly assured character. Completing the presentation, a dark blue alligator Mississippiensis strap secures via an 18K 5N pink gold ardillon buckle, keeping the material palette consistent throughout.
Reference 85180/000R-B515 is a study in restrained proportion and considered detail — a dress watch that communicates through subtlety rather than embellishment.
