Replica Jaeger-LeCoultre dress watches copy two lines: Master Ultra Thin and Reverso. Prices run $200 to $600. Most use Japanese Miyota or Chinese automatic movements. Case sizes match the originals within 0.5 mm. The best replicas use sapphire crystal and 316L stainless steel.

It runs at 28,800 vph and has a 38-hour reserve. The third is a decorated automatic with a fake rotor engraving. Power reserve is 36 to 40 hours. None match the finishing of the JLC caliber 925.
Case and dial details

Indexes are applied. Hands are dauphine or baton. Sapphire crystal appears on $300 and up. Mineral glass appears below $200.
Sizing and fit
Dress watches sit under a cuff. Case diameter should be 36 to 39 mm for a 6.5 to 7.5 inch wrist. Lug-to-lug should stay under 46 mm. The Master Ultra Thin Moon has a lug-to-lug of 46 mm. Replicas add 0.5 to 1 mm. Strap width is 20 mm on most Master Ultra Thin copies. Reverso copies use 20 mm or 22 mm straps.
Price tiers
- $150 to $250: mineral glass, Chinese automatic, printed dial.
- $250 to $400: sapphire crystal, Miyota 9015, applied indexes.
- $400 to $600: 904L steel, clone ETA 2824, real moonphase disc.
What to check
- Movement: ask for Miyota 9015 or ETA clone. Avoid unbranded 21-jewel movements.
- Case thickness: ask for 9.5 to 10.5 mm. Anything over 11 mm is wrong.
- Crystal: sapphire only. Mineral glass scratches.
- Moonphase: real disc or printed? Printed fails after one year.
- Water resistance: 3 ATM minimum. 5 ATM is better.
Limits
Replicas do not use JLC in-house movements. Finishing on bridges and rotor is basic. Gold plating fades after 12 to 24 months. Servicing a replica costs $80 to $150. No replica holds value. Genuine JLC Master Ultra Thin Moon costs $7,500 to $12,000 used. That is 15 to 30 times the replica price.
