Short answer
366395 is not a Cartier factory reference. Cartier writes references as a letter plus digits, such as W69012Z4 on a Ballon Bleu. The string 366395 turns up in marketplace listings, auction paperwork and dealer stock files tied to Pasha de Cartier watches. It can be an internal stock number, a lot number, or a code a seller made up. Until you see a caseback photo and a movement photo, the number says nothing about the watch.
What the Pasha line covers
Cartier dates the Pasha de Cartier design to 1985. Sub-lines followed, including the Pasha C, the Pasha Seatimer and the Pasha 41 mm. Between them the cases run from about 35 mm to about 42 mm, in steel, yellow gold, white gold and two-tone. Movements include ETA-based calibers and Cartier calibers. A single number such as 366395 cannot identify all of that.

How Cartier references work
- Format: letter prefix, digits, letter suffix. Example: W69012Z4.
- Serial number: stamped or engraved on the caseback, tied to the reference.
- Papers, box and service card should repeat both numbers.
- Marketplace codes sit outside this system. They are seller tools, not Cartier codes.
Counterfeit tells on a Pasha
- Caseback engraving is shallow. Letter shapes are wrong. Edges look stamped, not cut.
- Reference on the case does not match the number on the card or the listing.
- Crown: the real Pasha crown sits under a screw-down cap with a small chain link. Copies miss the chain, use a plastic cabochon, or omit the cap.
- Date window: wrong font, off-center, or a cyclops that sits crooked.
- Movement photos show a generic clone with no ETA or Cartier marks.
- Bracelet end links show gaps. Clasp stamping is light. Case weight is lower than a genuine piece.
Checks to run before you pay
- Ask for a sharp, straight-on photo of the caseback with light angled across the engraving.
- Write down the reference and the serial from that photo.
- Ask for a movement photo and a caseback thread photo.
- Take the numbers to a Cartier boutique or an independent watchmaker who services Cartier. Cartier after-sales can confirm or refuse a watch by serial.
- Compare the price with the market. Steel Pasha watches sell in the low four figures on the pre-owned market. A price far under that points to a counterfeit.
Cost and risk
A counterfeit watch has no factory service, no parts supply and no resale value. US Customs can seize counterfeit shipments. Selling a counterfeit as genuine is a federal offense. If 366395 is the only model number a seller gives you, treat the offer as unverified and walk away or demand proof.
