What Is a Fake Rendez-Vous Moonphase?
A fake Rendez-Vous Moonphase is a replica of the Cartier Rendez-Vous Moon, a women's dress watch that displays the lunar cycle through a curved aperture on the dial. Replica versions run from inexpensive quartz models with a painted moon disc to automatic copies that advance a real moonphase wheel once every 24 hours. The movement inside decides the quality far more than the box, papers, or paperwork that ship with the watch.
How Does the Moonphase Complication Work?
A lunar month lasts about 29.53 days, so a true moonphase mechanism uses a 59-tooth wheel that advances one step per day and shows two full moon cycles before repeating. A small finger on the hour wheel pushes the disc forward, which is why the moon changes position at roughly the same time each day. After about two and a half years the display drifts by one day against the real sky.
Does the Moon Disc Move Every Day on a Replica?
On a genuine moonphase it does. On many budget replicas the moon is simply printed on a disc that rotates with the seconds or stays fixed behind the aperture. Watch the dial for two minutes: if the moon creeps along with the running seconds, the complication is decorative.
What to Inspect on a Replica Rendez-Vous Moon
- Aperture shape. The genuine window is a wide crescent, not a plain circle, and its edges should be crisp and polished.
- Moon rendering. Look for a textured moon with subtle craters rather than a flat white sticker or a printed pattern.
- Dial finish. Guilloche or flinque texture should catch light evenly, and printed Roman numerals should be sharp with no ink bleed.
- Hands and crown. Sword-shaped blued hands and a cabochon-set crown are the two details most often cheapened on replicas.
- Case and crystal. Case proportions and sapphire with anti-reflective coating separate a mid-tier copy from a low-tier one.
- Caseback and strap. Engraving depth, a signed clasp, and a leather strap with real stitching all signal better assembly.
Quartz vs Automatic Replica Moonphase Watches
Quartz copies are thinner, cheaper, and need a battery, but most of them fake the lunar display entirely. Automatic copies use a modified or cloned movement with a genuine moonphase module, which adds height and cost. If the moon matters to you, automatic is the only tier worth considering.
How Accurate Is a Replica Moonphase Over Time?
A working replica moonphase usually tracks the cycle within a day or two per month, similar to a genuine mechanical moonphase. Setting it is simple: advance the crown until the moon sits at the correct phase, and avoid adjusting near midnight when the gear is engaged.
Legal and Practical Considerations
Cartier's dial layout, case shape, and name are protected trademarks, and selling or importing counterfeits is illegal in the United States and most of Europe. Customs agencies seize counterfeit watches regularly, and a seized parcel is rarely recoverable. Treat any replica purchase as a risk you accept knowingly.
Care Tips for a Replica Moon Watch
Keep the watch away from magnets, since a moonphase module sits close to the dial and a magnetized movement loses time. Service the moonphase disc every three to five years if the watch runs daily. Store it face up in a dry case to protect the moon aperture from dust and moisture.
