Short answer

A replica Jaeger-LeCoultre Rendez-Vous is a copy of a woman's watch line. Jaeger-LeCoultre introduced the Rendez-Vous in 2012. Genuine models use in-house Jaeger-LeCoultre movements. Copies use quartz or third-party automatic movements. The string "3944520" is a listing number used by a seller or an online catalog. It is not a Jaeger-LeCoultre reference. It carries no data about the watch itself.

What the Rendez-Vous line is

The Rendez-Vous is a round women's watch. Case sizes run from 29 mm to 34 mm. Metals are stainless steel, pink gold, and white gold. Many versions carry a diamond-set bezel. The Night & Day model shows a day and night disc at 6 o'clock. The Moon model adds a moon phase. The Celestial model adds a star chart.

Movement details

The Rendez-Vous Night & Day uses Calibre 898A/1. It is an automatic movement with about 40 hours of power reserve. Replica listings name a movement in a minority of cases. When they name one, the names are Miyota and Seagull. Most copies use quartz. Quartz keeps the case thin and the cost low. A quartz copy has a ticking seconds hand. The genuine watch has a sweeping seconds hand.

Prices

Genuine Rendez-Vous prices change by year, metal, and market. Steel models cost several thousand US dollars. Gold models with diamonds pass $20,000 in most cases. Replica listings run from $150 to $700. A $150 copy is quartz with a plated case. A $500 copy may use an automatic movement and a sapphire crystal. No replica carries an in-house movement. No replica carries a Jaeger-LeCoultre warranty.

How to read a listing

  • Case size. A Rendez-Vous case measures 29 mm to 34 mm. A listing that states 40 mm is a different case.
  • Reference format. Jaeger-LeCoultre references start with the letter Q, followed by digits. A seven-digit number with no Q is a seller code.
  • Movement. Ask for a photo of the movement and the rotor. A quartz copy has no rotor.
  • Box and papers. Genuine sets ship with a numbered warranty card. Copies ship with blank cards or none.

Legal status

Counterfeit watches are illegal to traffic in the United States under 18 U.S.C. 2320. Customs and Border Protection can seize shipments. Penalties include fines and prison time. A watch that carries the Jaeger-LeCoultre name and logo is a counterfeit, not a homage.
