A fake Cartier Santos 2018 is a counterfeit copy of the Santos de Cartier that Cartier relaunched in 2018. The genuine watch is a steel automatic sold under references such as WSSA0009 (large) and WSSA0010 (medium), and it uses the in-house Caliber 1847 MC along with two Cartier conveniences, QuickSwitch and SmartLink. Most copies reproduce the shape of the case and bracelet while skipping the working details, so a fake Cartier Santos 2018 can be identified with the watch in hand and no tools.

What the 2018 Santos de Cartier actually is

The 2018 relaunch replaced the older, thicker Santos 100 with a slimmer case, a more curved profile, and the squared bezel with eight visible screws that defines the line. Key traits of the real watch include:

  • A steel case of about 39.8 mm across and 47.5 mm lug to lug on the large version
  • A Roman numeral dial with a date window at 3 o'clock and "Swiss Made" at 6 o'clock
  • Sapphire crystal, screw-down crown with a faceted blue cabochon, and water resistance rated to 100 m
  • An automatic Caliber 1847 MC, visible only through the caseback on service benches since the watch ships with a solid engraved back
  • QuickSwitch, which releases the bracelet or strap when you press the tab under the lug, and SmartLink, which lets you add or remove bracelet links by hand

Many 2018 sets include a second strap in the box because the whole point of QuickSwitch is swapping without a trip to a watchmaker.

How to spot a fake Cartier Santos 2018

  • Strap and bracelet release: if a spring bar tool is needed to change the strap, the QuickSwitch mechanism is missing. Ask to see the swap done.
  • SmartLink: genuine links come out by hand with a small internal release. Stiff pins, loose rivets, or links that will not separate point to a copy.
  • Bracelet finishing: links should sit tight with no rattle, alternating brushed and polished surfaces, and no sharp edges on the underside.
  • Bezel screws: check slot depth and alignment. Shallow slots, burrs, and tooling marks around the screws are common on replicas.
  • Dial printing: the numerals and the signature should be crisp. On many Cartier dials the VII numeral hides a micro-printed signature, and copies almost never resolve it.
  • Crown cabochon: the blue stone should be faceted and set flush, not a flat plastic dot in the wrong shade.
  • Caseback engraving: reference and serial numbers should be cut sharply and match the case metal. Blurry or mismatched engraving is a warning sign.
  • Seconds hand: a smooth sweep means a mechanical movement. One tick per second means quartz, which the genuine 2018 Santos is not.
  • Weight: steel has heft. Plated brass copies feel light for their size and warm up fast in the hand.

Movement and caseback checks

Because the Santos de Cartier has a solid engraved caseback, a seller showing an open back with a generic rotor is showing a different watch or a modified one. Movement checks matter most during service: the 1847 MC is an in-house automatic, while replicas run on third-party or cloned movements with different jewel counts, rotor engraving, and finishing. If you cannot see the movement, judge the watch on the QuickSwitch system, the dial print, and the caseback engraving instead.

Why this reference gets copied so much

The Santos is one of the most recognizable square watches on the market, and the 2018 version made it thinner and easier to wear than the model it replaced. That combination of brand recognition and everyday usability keeps demand high, and counterfeiters follow demand. It also helps the copyists: a square case with a flat dial is easier to reproduce than a complicated round case, so fakes of this reference appear in large numbers.

Legal and buying reality in the US

Counterfeit watches are seized at the border when detected, and personal use is not a defense. U.S. Customs and Border Protection treats counterfeit merchandise as subject to seizure, and trafficking in counterfeit goods carries federal penalties. Beyond the legal side, a fake Cartier Santos 2018 has no Cartier warranty, no access to official service, no parts support, and almost no resale value. Anyone buying one should treat the money as spent.

Quick checklist

  1. Press the lug tab and swap the bracelet. Does it release without tools?
  2. Remove a link by hand. Does SmartLink function?
  3. Inspect the bezel screws, dial print, VII numeral, and crown cabochon.
  4. Read the caseback engraving and compare it to the reference printed on the paperwork.
  5. Watch the seconds hand. Smooth sweep or one tick per second?
