The short answer
Cartier has never issued a Pasha reference number of 366396. That string shows up in marketplace listings, auction lot sheets and dealer spreadsheets as an internal stock or inventory code. When a seller calls it "the model number," you are almost certainly looking at a replica listing that copied a stock code off a wholesale sheet. Real Pasha references read like W31074M7, WSPA0018 or WGPA0014, and they are printed on the caseback and the guarantee card.
So the code itself is the first red flag. It is not proof of anything on its own, but it tells you the seller is either confused about what they own or hoping you will not check.
Where the number comes from
I see these six-digit codes recycled constantly. Auction houses tag lots with internal numbers, grey-market dealers use their own SKUs, and photo aggregators keep database IDs in the file names. Replica sellers screenshot those listings, strip the real details and paste the leftover code into their own ads. If you search the number, you usually find the same watch photographed from the same three angles on a dozen different stores, with different prices.
Check the case and crown cap first
The Pasha is a strange watch, which makes it hard to copy well. Look for these:
- The crown sits under a screw-down cap attached to the case by a small chain or a fixed arm. On replicas, this cap is often the wrong shape or the chain is a cheap link that hangs wrong.
- The Vendome lugs are smooth and continuous. Fakes frequently show a visible seam or a rough polish line where the lug meets the case.
- The case is thick and heavy. If the watch feels light in the hand, the case is a plated base-metal shell, not steel or gold.
- Water resistance is usually fiction on a replica. Never trust a Pasha you cannot verify.
Dial and date window
Cartier dial printing is crisp and evenly spaced. On fakes the "Cartier" script looks slightly fat, the Roman numerals are too thick, and the railway minute track wobbles. The date window is a good tell. On authentic Pashas it is cleanly cut with a slight bevel; on copies it is a punched square with rough edges, and the date sits too far left or right. The blued hands should have a mirror finish with a sharp tip, not a soft, cloudy blue.
Caseback engraving and movement
Engraving depth separates real from fake more reliably than anything else on this watch. Genuine casebacks have deep, sharp lettering with consistent spacing, and the reference and serial numbers are stamped, not laser-etched onto a flat surface. Open the back if you can. Genuine Pashas run on Cartier calibres based on proven Swiss movements, and the finishing under the rotor is clean. Replicas usually carry unbranded Chinese automatics with visible machining marks and no regulation screws.
Bracelet, clasp and box
The Pasha bracelet uses a specific link profile. Fakes often have links that are slightly too flat, and the clasp engraving is shallow or doubled up. Papers matter too. A real Pasha comes with a guarantee card that matches the case serial exactly. If the card is blank, printed on flimsy stock, or the serial does not match, walk away.
Questions worth asking before you pay
- What is the reference number on the caseback? If the answer is a six-digit stock code, stop.
- Can you send a photo of the caseback and the guarantee card side by side?
- Has the watch been serviced, and by whom? A real Cartier service receipt is hard to fake.
- Is the price realistic? A steel Pasha with a genuine movement does not sell for a few hundred dollars.
Bottom line
Treat 366396 as a filing label, not a watch reference. Judge the watch on its case, its engraving, its movement and its paperwork. If any of those four checks fail, the listing is the replica, no matter how good the photos look.
