The Cartier Santos 2018 is the relaunch model Cartier showed at SIHH 2018, with a 39.8 mm by 47.5 mm steel case at 9.08 mm thick, Caliber 1847 MC automatic movement, QuickSwitch strap release and SmartLink bracelet sizing. A fake Cartier Santos 2018 that is worth owning copies those exact proportions and that movement layout. The versions to skip get the case width, the dial print, or the crown cabochon wrong.
What defines the Cartier Santos 2018 reference?
The 2018 relaunch moved the line away from the older, thicker Santos 100 shape into a slimmer square profile. The large steel model measures 39.8 mm across with a 47.5 mm lug to lug span, while the medium model comes in at 35.1 mm. Both run the in-house Caliber 1847 MC automatic, rated to 100 m and about 42 hours of power reserve at 28,800 vibrations per hour.
Cartier also added QuickSwitch, a spring loaded lug that frees the strap by hand, and SmartLink, which removes bracelet links without tools. Replicas rarely copy both systems correctly, so those two features are the fastest way to sort a good build from a bad one.
How do you check the case and bezel on a replica?
- Bezel screws sit flush with the surface and line up on a clean vertical axis.
- Bezel top is brushed, while the flank and the case sides are polished.
- Crown cabochon is a domed blue stone, spinel on steel and sapphire on gold, never flat plastic.
- Caseback engraving has even depth and crisp reference and serial text.
What should the dial and hands look like?
Roman numerals print in a flat silver white with sharp serifs, and the minute track stays clear of the numerals rather than touching them. Hands are sword shaped with a polished steel finish, and on many references the seconds hand carries a blue tone. On many Cartier dials the brand name hides inside the VII numeral, so inspect that area under magnification.
A correct automatic shows a smooth sweep at 28,800 vibrations per hour. A ticking or stuttering seconds hand means a quartz module sits inside the case.
Which bracelet details matter most?
SmartLink links release with a press on the underside button, and the bracelet should taper from roughly 23 mm at the lugs on the large model. Screw heads on the bracelet sides should be uniform, flush and machined, not punched or glued into place. QuickSwitch lugs should click in and out by hand and hold a strap tight under a firm pull.
What movement options do replicas use?
Higher tier replicas use a Chinese made automatic clone of the ETA 2824 or a decorated movement styled after the 1847 MC, both beating at 4 Hz. Entry level versions use quartz or a low beat automatic that steps instead of sweeping. Ask the seller for a movement photo and check the rotor engraving, jewel count and balance wheel position.
Red flags on a fake Cartier Santos 2018
- Case width off by more than 0.5 mm from the 39.8 mm large model figure.
- Printed or painted screws on the bezel instead of real screw heads.
- Roman numerals that crowd or overlap the minute track.
- Cabochon that is flat, scratched or the wrong shade of blue.
- Bracelet screws that strip or sit proud of the link surface.
Frequently asked questions
Is the Santos 2018 the same as the Santos-Dumont?
No. The Santos-Dumont is a separate, thinner line with a smooth bezel and, on most references, no date. A listing that swaps the two names is usually describing the wrong watch.
How much should a good replica cost?
Price tracks movement and finishing rather than the logo on the dial. A build with a genuine automatic clone and working SmartLink sits far above a quartz version, so compare specs instead of photos alone.
Does the large 2018 Santos wear big?
The 47.5 mm lug to lug span wears closer to a 40 mm round watch because the square case hugs the wrist. Thickness is the real factor at 9.08 mm, and a replica that runs thicker than 10 mm will look wrong on the wrist.
