Short answer
161889 is not a Cartier reference number. Cartier Santos references use letter and digit blocks, such as WSSA0009 or W2SA0009. A listing marked "fake Cartier Santos 161889" uses a seller SKU. That SKU points to a replica of the Santos de Cartier large model in steel with a steel bracelet. The digits carry no information about the watch. Ask the seller for case size, movement, and weight before you treat the number as a spec.
The watch behind the copy
Louis Cartier designed the Santos in 1904 for the pilot Alberto Santos-Dumont. Cartier relaunched the line in 2018 as the Santos de Cartier. Facts on the large steel model: case width 39.8 mm, thickness 9.38 mm, water resistance 100 m, sapphire crystal, calibre 1847 MC automatic movement, 42 hour power reserve, 28,800 vibrations per hour. The bezel is square with eight exposed screws. The dial carries Roman numerals, sword hands, and a date at 3. The crown holds a blue synthetic spinel cabochon. The bracelet has a quick release system Cartier calls SmartLink.

What sellers ship under that SKU
- Case: 316L steel, 39.8 mm on the better grades. Older stock copies at 38 mm and 40 mm.
- Movement: quartz on entry stock, Miyota 9015 or an Asian clone of the 2824 on mid grades, decorated clones with a fake rotor stamp on top grades.
- Gold look: plating from 1 to 5 microns on two tone and yellow versions. Plating wears through at the clasp and crown.
- Crystal: mineral glass on low grades, sapphire on mid and top grades.
- Water resistance: gaskets are fitted, no pressure test is done. Do not swim in it.
- Weight: a plated replica runs light against a solid gold case. Steel against steel is closer.
Checks before payment
- Ask for a photo of the caseback engraving. Depth and edge sharpness show the case quality.
- Check the eight bezel screws. Heads should sit flush and be polished, not domed or off center.
- Read the dial print. Look at letter spacing in CARTIER and the weight of the SANTOS DE CARTIER line.
- Look at the date window. It sits under 3 and has no frame on current models.
- Confirm beat rate. A quartz tick once per second. The 1847 MC and the Miyota 9015 both run at 4 Hz, so ask for a video.
- Ask for the bracelet screw type. Genuine links use screws, not pins.
- Ask for total weight in grams and compare it to the listed materials.
Price and legal notes
Replica Santos prices run from about 90 USD for quartz stock to about 600 USD for the top automatic grade. A steel Santos de Cartier at retail starts near 7,000 USD. A price far under retail is the main signal that the watch is not genuine. In the US, trafficking in counterfeit goods is a federal offense under 18 U.S.C. 2320. CBP seizes counterfeit watches at ports of entry. A counterfeit watch is illegal to resell, and Cartier will not service one.
What no replica delivers
Cartier warranty, service history, and parts support. Movement finishing and engraving depth differ from the genuine piece. Water resistance is unverified. Resale value outside the replica market is zero. The 161889 listing is a stock code for a copy, and it should be priced and judged as a copy.
