Short answer

"Fake pasha 366338" is a search string. It pairs a replica Cartier Pasha with the number 366338. That number is not a Cartier reference code. Cartier uses a letter and digit format, such as W31055M7 or WGPA0014. Eight digit numbers match listing IDs on resale sites, where each watch gets its own item number. The string points to one listing, not to a model line. If a seller calls 366338 a Cartier reference, that claim is wrong.

What the Pasha is

Cartier released the Pasha de Cartier in 1985. Gérald Genta designed it. The name comes from a 1930s commission for Thami El Glaoui, Pasha of Marrakesh. The line covers the 35 mm and 38 mm three hand models, the 41 mm chronograph, the 42 mm Seatimer, and the 2020 relaunch in 41 mm. Case metals include steel, yellow gold, pink gold, and two tone. Shared details: round case, Vendôme lugs, four Arabic numerals at 12, 3, 6, and 9, a screw down crown cap, and a blue cabochon on the crown.

Replica build grades

Pasha replicas come in three bands. Entry builds cost $60 to $120 and use a DG2813 automatic or a quartz movement. Mid tier builds cost $150 to $300 and use a Miyota 9015 or a Seagull ST21. Top tier builds cost $350 to $500 and copy the 1847 MC or the 049 calibre layout. Case thickness runs 1 mm to 2 mm over genuine spec on most entry builds. Genuine 35 mm steel Pasha automatic watches sell used for about $3,000 to $5,000.

Checks on a replica Pasha

  • Caseback: genuine engraving is deep and sharp. Replica engraving is shallow and soft at the edges.
  • Crown cap: genuine caps thread on in three turns and sit flush. Replica caps wobble or sit high.
  • Dial print: genuine "CARTIER" has clean serifs. Replica print shows filled or broken serifs.
  • Numerals: genuine applied numerals have polished sides. Replica numerals are flat.
  • Cabochon: genuine blue spinel has a smooth dome. Replica stones show bubbles or a plastic look.
  • Weight: a genuine 35 mm steel Pasha weighs about 110 g on the bracelet. Replicas run light.
  • Movement: open the caseback. An ETA or Cartier marked rotor with fine perlage points to a higher grade build. A bare rotor points to entry level.
  • Crystal: genuine sapphire has an anti reflective coat on the inside. Cheap builds use mineral glass that a steel pin scratches.

Legal note

A watch that carries the Cartier name, the Cartier logo, or a Cartier reference code is a counterfeit under US trademark law. US Customs and Border Protection can seize such goods at import. A seller who describes a counterfeit as genuine breaks the law.

Unknowns

The listing behind 366338 is not public record here. Case size, movement, and price for that single item cannot be confirmed from the number alone. Ask the seller for photos of the caseback, the crown cap, and the movement.
