Short answer
"Fake Cartier Caliber 42mm" means a replica of the Calibre de Cartier automatic, a 42 mm watch Cartier introduced in 2010. The genuine watch runs Cartier's own 1904-PS MC movement. Most replicas run a bought-in clone of an ETA 2824 or a Seagull ST2130. Replica cases copy the outline well. The movement, the crown cabochon and the dial print are where the gaps show.
Genuine specs to compare
- Case: 42 mm across, steel or rose gold, brushed flanks with polished bevels.
- Movement: Calibre 1904-PS MC, automatic, 27 jewels, 28,800 vph, about 48 hours of power reserve.
- Caseback: sapphire display back fixed with screws.
- Crown: faceted, set with a blue sapphire cabochon.
- Dial: applied Roman numerals, rail-track minute ring, date at 3 o'clock.
- Water resistance: 30 m on the automatic reference.
Check beat rate and power reserve first. A movement that runs at 21,600 vph with a 40-hour reserve is not a 1904-PS MC, whatever the rotor engraving says.

Where replicas differ
Movement
A clone ETA 2824 and a Seagull ST2130 both beat at 28,800 vph, so the seconds hand sweep looks correct. The finish does not. Look at rotor engraving depth, the perlage under the balance and the bridge shape. Cartier finishes the 1904-PS MC with Geneva stripes and a signed rotor. Replica decoration is stamped, not cut, and the text sits shallow.

Case and crown
Replica cases run thick at the lugs and the bevels are cut wider. The crown is the second tell. A real sapphire cabochon has deep, even blue and a smooth dome. Replica cabochons are glass or dyed spinel, and the color shifts purple under a strong lamp.
Dial and print
Genuine Roman numerals are applied, with crisp edges. Replica numerals are glued and sit high. Compare the date font, the spacing of the rail track and the Cartier signature. Print that looks heavy or spreads at the edges points to a replica dial or a repaint.
Price tiers for replicas
- Low tier, about $80 to $150: quartz or a low-grade automatic, printed dial, glass cabochon.
- Mid tier, about $200 to $400: clone 2824 or ST2130, sapphire crystal, steel case.
- Top tier, about $450 to $700: decorated movement, better dial print, closer case finishing.
No tier gets a real 1904-PS MC. Cartier does not sell that movement as a spare part to the public.
Legal status in the US
Trafficking in counterfeit goods is a federal crime under 18 U.S.C. 2320, with penalties up to 10 years for a first offense. US Customs and Border Protection seizes counterfeit watches at ports and destroys them. Importing a counterfeit watch is prohibited, so a shipment can be seized and the money lost. Selling a replica as genuine also exposes the seller to civil claims under the Lanham Act.
Checks before you accept a watch as genuine
- Reference number on the caseback matches the dial layout and the case material.
- Caseback screws sit flush and evenly spaced.
- Movement photo shows Geneva stripes, a signed rotor and a timed 48-hour reserve.
- Weight: a steel Calibre 42 mm on bracelet feels heavier than the replica.
- Box, papers and warranty card carry a serial that matches the case.
