The fake Rendez-Vous Moonphase 240 is a replica of the Jaeger-LeCoultre Rendez-Vous Moonphase. The "240" label comes from certain replica factories as a batch or grade code. It does not match any official Jaeger-LeCoultre reference. Replica versions copy the 36mm case size, the moonphase display, and the textured dial, but build quality ranges from crude to surprisingly close.
What the 240 Code Means
In replica watch circles, numbers like 240 often indicate a specific factory run or a version number. For the Rendez-Vous Moonphase, "240" may refer to a particular moonphase disc diameter, a movement batch, or an internal model code used by a maker. Treat the 240 label as a seller's shorthand, not a guarantee of quality.
Genuine Specs to Compare
The genuine Rendez-Vous Moonphase uses the Jaeger-LeCoultre Caliber 925A/1 automatic movement. The case measures 36mm in diameter and comes in stainless steel or rose gold. The crystal is sapphire. The dial features a guilloché pattern and a moonphase aperture that shows the lunar cycle. Replica 240 versions should be checked against these points.
Moonphase Accuracy Check
A real moonphase complication uses a precise gear ratio. It stays accurate for 122 years if kept running. Replica moonphase displays often use a simplified mechanism. To test a fake Rendez-Vous Moonphase 240, set the moonphase to a known full moon date. Then advance the time forward several days. The moon disc should move in small, even steps. If it jumps or drifts, the mechanism is poor.
Case, Dial, and Crystal Inspection
Look at the case finishing. Genuine models have sharp, polished bevels and brushed surfaces. Replicas often show rounded edges or uneven brushing. The crystal should be sapphire, not mineral glass. Tap the crystal lightly; sapphire has a sharper sound. Check the dial printing under magnification. The guilloché pattern on a good replica should be crisp, not blurry.
Movement and Finishing
If the seller provides photos of the caseback, examine the movement. Genuine Caliber 925A/1 has Côtes de Genève stripes, blued screws, and perlage. Replica movements may show a decorated rotor but lack the same finish. Many fake Rendez-Vous Moonphase 240 watches use a Miyota or Seagull automatic movement. That can be reliable, but it is not the same as the JLC caliber.
