A fake Rendez-Vous Night & Day is a replica of the Jaeger-LeCoultre Rendez-Vous Night & Day, a women's automatic watch whose signature feature is a 24 hour day and night aperture at 6 o'clock that alternates a sun and a moon. A faithful replica copies three things: the case profile, the textured dial, and a disc that completes one full rotation every 24 hours. Most buyer complaints trace back to the third item, because cheap copies freeze the sun and moon or tie the disc to the 12 hour hand.
What makes the Night & Day indicator different from a moon phase?
A moon phase tracks the 29.5 day lunar cycle, so it drifts out of sync with the calendar unless you reset it. The Night & Day is a simple 24 hour indicator: a sun for daytime hours, a crescent moon for nighttime hours, back to the same position once a day. That simplicity is why replica makers can copy the look convincingly at a low price, and also why low-grade versions fake it with a printed aperture and a disc that never moves.
Which replica tiers exist and what do they cost?
- Quartz tier, roughly $60 to $150: plated alloy case, mineral glass, printed or motorized disc, stamped synthetic strap.
- Entry automatic, roughly $180 to $380: 316L stainless steel case, sapphire crystal on better examples, and a disc that genuinely rotates once per day.
- High-end automatic, roughly $400 to $800: clone or modified Swiss-pattern automatic, correct proportions, applied indices, anti-reflective sapphire, and bezels set with cubic zirconia or moissanite.
How do you verify the day and night disc before buying?
Ask the seller for a short video rather than a still photo. Set the watch, let it run, and confirm the aperture edge lines up with the printed scale around it. On a correct replica the disc advances with the hour hand and reaches the moon segment in the evening.
- Motion: the disc should turn once every 24 hours, not once every 12.
- Alignment: sun and moon should sit centered inside the 6 o'clock aperture at the reference point.
- Finishing: check for a polished bevel on the aperture edge and no paint bleed onto the dial.
- Type and scale: numerals, minute track, and hand shape should match the specific reference you are ordering.
What are the most common red flags?
Stock photos lifted from the brand's own catalog are the first warning sign, since sellers who own the watch photograph it in hand. A listing that claims a Swiss movement without showing the caseback or a timing reading is guessing. No return window, no movement photo, and a disc that jumps in 12 hour steps all point to a quartz build dressed up as an automatic.
Case sizes, dials, and bezels to know
The line spans roughly 34 mm to 38.2 mm depending on reference, offered in stainless steel, pink gold, and diamond-set bezel versions. Dial families include silvered guilloche, blue sunray, and mother of pearl, each with its own texture that replicas often flatten. If you want a daily wearer, the steel case on a leather strap is the easiest reference to match well at replica level.
Do replica Rendez-Vous Night & Day watches keep time?
A clone automatic generally runs within about 15 to 25 seconds a day, which is acceptable for a dress watch worn a few times a week. Quartz versions keep better time but feel wrong in a hand finished case, and their second hand ticks instead of sweeping. Expect to reset the time after a weekend off the wrist unless the movement has a decent power reserve.
Is a replica worth servicing or waterproofing?
Service costs often approach the price of a mid-tier replica, so most owners replace rather than repair. Water resistance on replicas is rarely tested, so treat any rating as cosmetic and keep the watch away from swimming and showers. If you want a screw-down crown and a pressure test, that is a different category of watch entirely.
