What this page does not do
This page does not list sellers, sites, or markets for counterfeit Patek Philippe perpetual calendar watches. I will not write that guide. The reasons are legal and mechanical.
What to Look for in a Fake Patek Philippe Perpetual Calendar
Legal status in the United States
A counterfeit watch carries a copied trademark. US law targets the goods, not only the seller.
- 18 U.S.C. § 2320 makes trafficking in counterfeit goods a federal crime. A first offense involving a counterfeit mark on a watch carries up to 10 years and $2 million.
- 19 U.S.C. § 1526 bars importation of merchandise with a counterfeit mark. US Customs and Border Protection can seize and destroy a personal shipment. No refund follows.
- The Lanham Act, 15 U.S.C. § 1114, lets the trademark owner sue sellers and distributors and recover profits plus damages.
What a perpetual calendar movement contains
A true perpetual calendar tracks date, day, month, and leap year. It needs no correction until 2100. The mechanism holds 200 to 300 parts, or more. Patek Philippe builds it into references such as the 5320G and the 5740/1G. Retail runs from about $90,000.

Replicas sell for $200 to $800. That budget buys a stock automatic or quartz movement with printed subdials. The month disc moves with a pusher, not with the gear train. The date does not correct for February. A leap year window is a decal. Gear sets and cams for one real calendar module cost more than the whole replica.

Pre-owned prices move with papers, box, and service history. Ask for the serial number, a service invoice, and a photo of the caseback. A seller who refuses all three ends the conversation.
