Short answer
Counterfeit Vacheron Constantin Patrimony watches exist in large numbers online. Importing one into the United States is illegal under 19 U.S.C. 1526, and US Customs and Border Protection can seize the shipment. Selling counterfeits carries criminal penalties under 18 U.S.C. 2320. This page does not list sellers. It covers the genuine manual-wind Patrimony and the rules that apply to replicas.
The genuine Patrimony manual-wind
Vacheron Constantin builds the Patrimony as a round dress watch. Manual-wind references use the caliber 1400. Reference 81180 has a 40 mm case that measures about 6.8 mm thick. Cases come in pink gold and white gold. The case back is sapphire, so the movement is visible. Retail for a new gold Patrimony manual-wind sits near $25,000 and above.
Caliber 1400
The 1400 is a hand-wound movement about 2.6 mm thick. Vacheron Constantin lists a power reserve near 40 hours and 20 jewels. The movement carries the Hallmark of Geneva, an independent certification of origin, finishing, and assembly standards. Vacheron Constantin applies the hallmark to movements made in its Geneva workshops.
What replicas get wrong
Thinness is the hard part. A 2.6 mm movement inside a 6.8 mm case leaves little room for error. Replicas often use a thicker automatic movement, a quartz module, or a decorated base caliber. The result sits taller on the wrist. Winding feel differs. Other tells include bridge engraving, the Geneva Seal stamp, caseback text, and reference numbers that do not match Vacheron Constantin records.
Price on the secondary market
Used Patrimony manual-wind watches trade in the low five figures in US dollars. Final price depends on metal, condition, service history, box, and papers. Vacheron Constantin boutiques can verify a reference and serial number during service.

US law on counterfeit watches
- 19 U.S.C. 1526: importation of goods bearing a counterfeit trademark is prohibited. CBP can seize and destroy the goods.
- 18 U.S.C. 2320: trafficking in counterfeit goods carries prison terms and fines.
- 15 U.S.C. 1114: trademark owners can sue sellers for damages and profits.
Federal criminal law targets people who sell, distribute, or import counterfeits. A buyer who keeps one watch for personal use faces a lower risk of prosecution, but the item can still be seized, and there is no warranty, no service, and no recourse if the seller takes the money. Vacheron Constantin does not service counterfeit watches.
