CurrentPatrimony Contemporary Pink Gold
2014 — present
40mm 18ct pink gold automatic with silver dial. Calibre 2450 Q6/1.
The Vacheron Constantin Patrimony is perhaps the most perfectly proportioned dress watch made today. Its philosophy is absolute minimalism: an ultra-thin round case, a dial of perfect symmetry, and movement finishing of the highest order. The Patrimony Contemporary (ref. 81180, 85180) uses the Calibre 2450 Q6/1, an ultra-thin automatic movement occupying a case of just 8.09mm total thickness — thinner than many dress watches with far less prestigious movements. The Patrimony Perpetual Calendar (ref. 43175, 4100U) adds a perpetual calendar complication within the same ultra-thin architecture — an achievement of condensed mechanical intelligence that requires extreme movement miniaturization. Every Patrimony carries the Hallmark of Geneva, verifying the movement's decoration, finish, and accuracy. The name itself — patrimony, heritage — signals the watch's role as a heirloom timepiece. Pre-owned Patrimony watches are the choice of collectors who have moved beyond conspicuous luxury and appreciate the understated statement of extraordinary Geneva watchmaking.

Buying Guide
01
Patrimony 81180 in pink gold offers the same dress-watch ethos as the Patek Calatrava 5196 at $19,000–$24,000 pre-owned — significantly less than the Calatrava equivalent. Build quality is comparable; brand recognition is the differentiator.
02
The Patrimony Manual 4100U with hand-wound Calibre 1731 offers a more tactile ownership experience and slimmer profile. Sub-seconds at 6 adds visual interest. Trades $35,000–$48,000 in white gold — the connoisseur's Patrimony.
03
Patrimony service intervals are 5–7 years. Service costs $1,200–$2,500 at the manufacture and takes 4–6 months. Always verify recent service status when buying pre-owned.
Sizing
Patrimony 81180/85180 at 40mm with 44mm lug-to-lug fits virtually any wrist — one of the most universally wearable dress watches in production. The 8.09mm thickness slips easily under any cuff. The 4100U at 42mm is slightly larger; perpetual calendar 43175 at 41mm.
