Short answer
"Fake Pasha 366338" does not point to one watch. Cartier does not publish a Pasha model under six plain digits, and its own codes mix letters with numbers, as in W31012M7 or WGPA0014. The 366338 string turns up as a marketplace listing ID, an auction lot number, or a seller's stock code. So the phrase describes a listing that claims to be a Cartier Pasha, not a documented reference. What settles the question is the watch on the table, and a Pasha is one of the easier Cartier shapes to check once you know where fakes slip.
What 366338 actually is
Cartier reference codes are built from letters and digits. A bare six-digit string such as 366338 does not match any published Pasha reference I have come across. That alone does not make a watch fake, but it tells you the seller is not quoting Cartier's model code while claiming a genuine piece, which is a small warning sign. When a title leans on a number instead of a reference, the details in the photos have to carry the whole case.
What the Pasha is
The Pasha de Cartier arrived in its modern form in 1985 and was refreshed in 2020. The case is round and thick. The design is defined by one feature above all: a crown that sits under a screw-down cap, with the cap tied to the case by a short chain. That chain and cap are the heart of the watch. Get them right and you have a Pasha. Get them wrong and no dial work can rescue it.
The details fakes get wrong
- Crown cap and chain. On a real Pasha the cap threads on with a firm, even feel and sits flush against the case. The chain is short and fine, anchored to a lug with a well finished pin. Fakes show a loose cap, a chain that hangs too long, or a stamped link with sharp edges.
- Cabochon. The crown cap on most Pasha models takes a blue cabochon, spinel or sapphire depending on the version. Real stones catch light with depth. Fakes use resin or dyed glass that looks flat and cloudy within a month.
- Dial printing. Study the spacing in the "Pasha de Cartier" script and how the minute track meets the numerals. Fake printing runs thicker, and numerals sit a hair off the track. Cartier is a jeweler first, and its printing stays crisp under a loupe.
- Caseback engraving. Genuine engraving is cut into the metal, with reference, serial, and water resistance rating all present and readable under a lens. Fakes tend to be laser etched and shallow, and the same serial reappears across listings.
- Movement. Pasha watches have used quartz calibers and automatic ones. A real automatic shows a signed rotor and visible finishing. Fakes usually run a generic clone with an unsigned rotor and rough edges.
How to check one before you pay
- Ask for a sharp side photo of the crown cap and chain.
- Ask for the caseback with the serial legible, then search that serial. Recycled numbers are common.
- Weigh the watch. Replica cases often run lighter or heavier than the genuine steel case of the same size.
- Compare the price to the market. A steel Pasha trades in the thousands. A few hundred dollars buys a replica, never a genuine one.
- Have a watchmaker who handles Cartier open it. That is the only check that settles the question.
The bottom line
Treat 366338 as a listing number and nothing more. The Pasha is a watch you can verify with your eyes and a loupe if you know the crown cap, the cabochon, the printing, and the caseback. Everything else in that title is marketing.
