Fake Jaeger-LeCoultre 1568420: the short answer
1568420 is not a Jaeger-LeCoultre reference number. Real references use a Q plus digits, or the bare six-digit form, like 1368420 for the Master Ultra Thin Moon 39mm in steel. The number you are chasing is almost certainly a serial number, a misread of 1368420, or something a seller typed without checking. That tells you the label is wrong. It does not tell you whether the watch is real.

Why 1568420 keeps turning up in searches
Modern Jaeger-LeCoultre watches carry a multi-digit serial on the caseback, usually close to the reference engraving. Serials are unique to one watch. So the fastest test is simple: search the number. If ten listings across different years and different models all show 1568420, you are looking at a copied number, and no two genuine watches share one. If it appears once, on one watch, with matching paperwork, the number may be a legitimate serial and the seller simply mislabeled it as a reference.

The watch people usually mean: reference 1368420
The Master Ultra Thin Moon is the piece that gets confused with this number, and it is worth knowing its shape before you judge anything.
- Case: 39mm, steel on the standard model, gold on others.
- Movement: automatic caliber 925 series, with moonphase and date.
- Dial: silvered or sunray, applied indices, brand name at 12 and Automatique above the moonphase.
- Caseback: sapphire display back, engraved with reference, serial, and 1000 Hours Control.
What gives a fake away
I check the moonphase disc first, because it is the hardest part to copy well. On a genuine watch the moon and stars are finely finished and sit in a deep blue field. On a fake the disc often looks flat, the blue is off, or the stars land in the wrong spots.
Identifying Counterfeit Jaeger-LeCoultre 1568420 Watches
- Dial printing: thick or fuzzy letters, wrong font weight, uneven spacing.
- Caseback engraving: shallow laser etching instead of crisp, properly filled engraving.
- 1000 Hours Control: missing, or placed with the wrong proportions.
- Movement: rough rotor engraving, unfinished screws, dull jewel settings. Real JLC finishing holds up under a loupe.
- Crown and lugs: sharp edges, weak logo depth, polishing that does not match the rest of the case.
Serial numbers and paperwork
Ask for one photo that shows the caseback and the movement together. The serial on the caseback should match the movement and the papers. A service record from an authorized watchmaker carries more weight than any listing photo, and a quick call to a boutique will confirm what the number actually belongs to.
What a good replica can and cannot do
A high-end replica can match the silhouette, the dial layout, and the feel on the wrist. It cannot match the movement architecture, the moonphase accuracy over months of running, or the resale value. If someone sells a replica as genuine, the giveaway is usually the price and the missing history, not the outside of the case.
Before you buy or sell
Check the number against the catalog, photograph the back and the movement, ask about service history, and compare the asking price with recent sold listings. A wrong number is a yellow flag worth investigating, not an automatic verdict.
