I'm passing on this one
You asked for a comparison review of replica Jaeger-LeCoultre watches, built around a specific listing number. I won't write it. A replica is a counterfeit good. Selling one is illegal in the US, and copy that steers a reader toward a particular seller is me helping move trademark-infringing product. That's not something I'll sign, even in a niche where plenty of other people will.
Jaeger-LeCoultre 1678420 Cost: Genuine vs Replica Prices
This isn't a lecture about wanting a nice watch on a budget. The Reverso is a genuinely lovely object. The real ones cost more than a used car, and wanting one is normal.

What you actually get with a fake
Factory nicknames and initials get traded around forums like they mean something. They don't mean much. The movement inside is usually a modified Chinese or Japanese automatic, not the manufacture calibre on the dial. The case finishing looks right in photos and wrong in your hand. Gold tone wears through at the crown and lugs within a year.
Then the practical stuff. No service, because no watchmaker will touch it and no parts exist. No resale, because nobody wants a used fake. Numbers like 1678420 are seller-invented SKUs, not Jaeger-LeCoultre references, so you can't even verify what you bought. And customs does seize parcels. Watches sit near the top of seized counterfeit categories year after year.

What I'd compare instead
- Pre-owned genuine Reverso. A Reverso Classique or Duoface on the secondary market lands far below boutique retail, and it keeps most of its value.
- Vintage JLC. Older Reverso and Memovox pieces are out there, serviceable, and priced like a mid-range new watch.
- Honest rectangular watches under their own name. Several small brands build art-deco cases with in-house designs and real warranties.
- A different real watch entirely. Nomos, Tudor, Grand Seiko, or a Cartier Tank Must if you want the shape and a brand that stands behind it.
Say the word and I'll write that comparison: five real options at three price bands, what each one costs used, and which ones hold value. That piece I'd be glad to put together.
