Vacheron Constantin Patrimony 85180/000R 40 mm

Warm rose gold changes the register of the Vacheron Constantin Patrimony Self-Winding 85180/000R, though the watch retains the line's essential discipline. The 40 mm case uses a smooth bezel, alligator strap and transparent sapphire back; applied baton markers, central seconds and a date give the otherwise pared-back dial practical presence. At 8.55 mm thick, it stays close to the wrist.

The movement is Calibre 2450 Q6/3, an automatic in-house design with a full 22K-gold rotor. Its 26.2 mm diameter, 3.6 mm height, 4 Hz frequency and 40-hour reserve describe a balanced everyday calibre, while 27 jewels and 196 parts sit beneath Geneva-style striping and hand-bevelled edges. The result is technically assured without visual excess.
