Short answer
A counterfeit AMVOX 2 fails the crystal test before anything else. On a genuine Jaeger-LeCoultre AMVOX2, the chronograph has no pushers. You start and stop it by pressing the sapphire crystal at 12 o'clock and reset it by pressing at 6 o'clock. If the watch has two pushers at 2 and 4, it is not authentic, no matter what the dial says. Every other check, from dial print to case back engraving, comes after that one.
What the AMVOX 2 is
The AMVOX2 is a Jaeger-LeCoultre sports chronograph introduced in 2005 under a partnership with Aston Martin. It measures about 44 mm across and uses a vertical trigger system instead of pushers. Later references include the Chronograph, the DBS, and the DBS Transponder, which carried a module that locked and unlocked an Aston Martin car. Because the layout is unusual, fakes separate from the real thing fast once you know where to look.
Before you inspect
- A 10x jeweler's loupe
- Digital calipers or a steel ruler
- The reference number the seller quoted
- Factory photos of that exact reference for comparison
Step by step checks
- Press the crystal at 12 o'clock with your thumb. A genuine AMVOX2 chronograph starts.
- Press the same spot again. The chronograph should stop.
- Press the crystal at 6 o'clock. The chronograph hands should fly back to zero.
- Look at the case flanks. Any pusher at 2 or 4 o'clock rules the watch out as authentic.
- Measure the case with calipers. The genuine case is about 44 mm wide. Fakes often come in at 42 mm or less on a reference quoted as 44 mm.
- Check the crown. It should be signed, sit flush with the case band, and show crisp knurling.
- Turn the watch over. Genuine examples carry an engraved reference and serial on the case back, along with the maker's name and Swiss Made in a clean font.
- Study the movement through the display back. You should see a JLC calibre with a signed rotor. A quartz movement, or a bare automatic with no markings, means a fake.
- Examine the dial print under the loupe. Genuine text is sharp with even spacing. Counterfeits show thick, uneven lettering, and the Aston Martin wings lose their fine lines.
- Compare the date window and subdials against the reference. Font, position, and aperture shape should match.
- Weigh the watch in your hand. Titanium references feel light but solid, with no rattle from a loose case back or bracelet.
Replica tiers and what they miss
Cheap fakes use quartz movements and glued case backs. Mid-range replicas add automatic movements and better dials but keep standard pushers, because the crystal trigger is hard to reproduce. Higher-end replicas copy the case shape well and still fall short inside. No aftermarket maker has produced a working vertical trigger at scale, so that one feature stays the fastest test you have.
If the watch is sold as genuine
Ask for the reference number, box, and papers. Compare the reference against the maker's catalog data before you pay. A seller who cannot supply a case back photo and a movement photo is a seller to walk away from. Counterfeit watches also carry legal exposure in the United States, where trafficking in counterfeit goods can trigger civil liability under trademark law.
After the sale
Take the watch to a watchmaker who services Jaeger-LeCoultre. They can open the case, time the movement, and confirm the calibre number against the reference. A service estimate from an authorized center settles the question, since no cosmetic check beats a movement inspection.
