The short answer
Fake Pasha blue is the search term people use for the blue-dial Cartier Pasha de Cartier and for the replicas built to copy it. For most buyers, the strongest pick is a high-tier replica with a sunray blue dial and a working crown chain, judged on four criteria: dial finish and color depth, crown and cabochon assembly, case and bracelet geometry, and the movement behind the caseback. Cartier's own blue-dial Pasha sets the benchmark at all four points. Every replica tier sits below it, and the gap shows first at the dial and at the crown.
What the term covers
The Pasha de Cartier is one of Cartier's oldest shaped designs, relaunched in 2020 with steel cases in 41 mm and 35 mm, a round case, a screw-down crown cap, a small chain linking that cap to the lugs, and four large Arabic numerals at the corners of the dial. Blue-dial versions sit inside that range. The phrase fake Pasha blue covers three separate situations: a replica of a blue-dial Pasha, a genuine Pasha with a swapped or refinished dial, and a genuine watch a seller is misrepresenting. The first is a quality question. The second and third are authenticity questions, and they need a different set of checks.
Criteria that decide the tier
Dial finish and color depth
Cartier uses a brushed sunray finish on the blue Pasha dial, so the color reads darker at the center and brighter toward the edges as light moves across it. Low-tier replicas print the color flat instead of brushing it, and the blue reads purple or gray in daylight. Mid-tier copies brush the dial but use a lighter base coat, so the watch looks brighter indoors and washed out in sun. The printed numerals are the second tell. On the genuine dial they are crisp with clean inner corners. On copies they often look thick, soft at the edge, or slightly off in proportion.
Crown, chain, and cabochon
The crown assembly is the hardest part to copy and the fastest way to sort tiers. The genuine piece has a fluted crown under a screw-down cap, a cabochon set into the cap, and a short chain that moves freely and sits flat against the case. Cheap replicas glue the cap shut, fit a chain that kinks or hangs loose, and use a plastic cabochon with a visible seam. Better copies get the chain right and use a synthetic stone, but the cabochon often sits too high in the cap or reads too dark.
Case and bracelet geometry
Check lug thickness, the curve where the bracelet meets the case, and the polish on the bezel edge. Genuine cases have a distinct step between the brushed caseband and the polished bezel, and the bracelet end links sit flush with no gap. Replicas in the low and middle tiers show a soft step, uneven brushing, or a visible gap at the end link. Weight matters too: a steel Pasha has real presence on the wrist, and a light copy usually means a hollow case or a thin bracelet.
Movement
Cartier fits an in-house automatic to the steel Pasha models, and a genuine caseback shows engraving with even depth and sharp edges. Replicas run anything from a quartz module to a decorated generic automatic. A quartz copy will tick once per second instead of sweeping, which is the simplest check anyone can do without opening the watch.

High-tier super clone Pasha blue
Pros
- Sunray dial and crown chain close to the original in normal viewing
- Correct case proportions and weight on the wrist
- Automatic movement with a sweeping seconds hand
- A fraction of the price of the genuine watch
Cons
- Still a replica, with no brand service or warranty

Mid-tier and budget Pasha blue
Pros
- Low entry price
- Fine for a costume piece or a gift that will not be inspected
Cons
- Flat or purple-tinted dial
- Fixed or fake crown chain, plastic cabochon
- Quartz ticking and light case weight
- Weak bracelet finishing and gaps at the lugs
Best avoided if the watch will be handled by anyone who knows the model. Use it only as a visual prop.
Red flags when you inspect one
- Seconds hand that ticks instead of sweeping.
- Dial blue that shifts purple or gray in daylight.
- Crown cap that does not unscrew or a chain that kinks.
- Cabochon with a seam, a flat top, or an oversize dome.
- Soft or shallow engraving on the caseback.
- Bracelet end links with gaps at the case.
- Seller who will not show the crown, the caseback, or a moving seconds hand on video.
Which version fits your use case
If you want the watch to pass a close look and you keep it for years, buy the genuine blue-dial Pasha. If you want the design on your wrist for daily wear without the price, a high-tier super clone is the sensible middle. If you need a one-off prop for a shoot or a costume, a mid-tier copy does the job and nothing more. Whichever route you take, judge the watch on the dial first, the crown assembly second, and the movement last, because that is the order in which the tiers separate.
