If you searched "fake baignoire 2020," you are probably trying to settle one question: is the Cartier Baignoire in front of you genuine, or is it a replica listed as a 2020 model? Short version first. The case shape decides it. Cartier's Baignoire is a curved oval that follows the wrist, and most replicas get the curve, the crown cabochon, or the dial printing wrong. When two of those three are off, the watch is not genuine.
Why "2020" appears in so many listings
The year is usually marketing, not a reference number. Sellers tag a watch with a recent year because it reads as current stock. Cartier has made the Baignoire for over a century, and the 2020-era catalog leaned on the classic oval plus the longer Baignoire Allongée, in sizes running from roughly 18 mm to the low 30s, with quartz or hand-wound movements depending on the case. None of that is visible in a single photo, which is exactly why the phrase gets attached to replicas.
Treat "2020" as a claim to check, not a fact. What you check is the watch.
The oval case is the hardest thing to copy
A real Baignoire is a true oval, and the profile is curved rather than flat. The case arches so the back sits against the wrist with only the edges touching. Replicas almost always start from a flat oval blank, so the watch sits like a coin on a table and rocks. Turn the watch sideways and look at the gap under the case. If the case back is flat and the lugs stick out at a hard angle, it is not Cartier geometry.
Look at the lugs too. On the genuine watch they blend into the case with a soft, continuous line. On replicas the lugs look bolted on, and the polishing between them is uneven or overdone.
The crown and the cabochon
This is where I look first, because it is cheap to fake badly and expensive to fake well.
- Genuine cabochons are domed sapphire or spinel, cut so light passes through the stone and the surface is smooth and round.
- Replica cabochons are glass, resin, or a coated bead. They read flat on top, too tall, or milky, and the colour drifts toward pink instead of a deep blue or black.
- The crown itself should follow the curve of the case, not sit as a straight cylinder.
Run a fingernail over the stone. A genuine cabochon is set flush with a thin metal lip, and there is no glue line or gap.
Dial printing and hands
Cartier dials are printed with a fine, consistent line. On a replica the Roman numerals look heavy or uneven, the serifs blur, and the spacing inside words like CARTIER is off by a hair. Turn the watch to a low angle. Genuine printing stays sharp; replica printing smears and the black looks grey or glossy.
Hands on the real watch are blued steel with faceted sides. Replicas are painted blue, so they flash purple under light and look flat. Also check whether the reference should even have a seconds hand. Many small Baignoire models run without one, so a ticking seconds sub-dial at 6 o'clock is a strong sign of a quartz replica built on a generic base.
Case back, engravings, and movement
Engravings on the back should be cut into the metal, not burned on top of it. Laser etching on replicas looks shallow and slightly frosted. Gold models should carry the correct hallmarks for their market, and those marks are often missing, wrong, or in the wrong place on fakes. If the listing says solid gold and the case back has no precious-metal stamp at all, walk away.
The case back also tells you how to open the watch. Snap-on backs on a case that should be screw-down, or the reverse, is a mismatch worth noticing.
Strap, buckle, and finish
Cartier straps are cut from a single hide with tight, even stitching and a pin buckle whose shape and font match the case era. Replica straps are thinner, the stitching wanders, and the buckle font is wider or heavier. Plated replicas also wear through at the lugs and crown first, so look for a lighter ring of metal where the strap rubs.
Quick check before you buy
- Lay the watch on a flat surface and look for the curve under the case.
- Inspect the cabochon with a phone light: domed, saturated, no glue line.
- Zoom on CARTIER and SWISS MADE for print weight and spacing.
- Confirm the hands are blued steel, not painted.
- Check that the reference on the case back matches the dial layout and case size.
- Ask for a movement photo, then compare it to the calibre the reference should use.
- Weigh it. Solid gold watches feel dense for their size.
What a good replica still cannot hide
Even the better fakes get the crown, the case back, and one dial detail wrong. That is enough. The Baignoire is a small, quiet watch, and small quiet watches show flaws fast because there is so little surface to hide behind. If the seller pushes the year, the box, or the papers but dodges photos of the crown and case back, the "2020" tag is doing the work the watch cannot.
