well they look similar but really have nothing to do with each other
andre bornand did make a pocket watch that was similar to the 3699 caliber but they have a "bornand" cage in copper beryllium rather than the cage made in steel in the jlc 170. However, i do think JLC made the school watch ebauches which were very similar to the 170 made with the 170 cage or a grether type 3 cage and sometimes had twin barrels. These ebauches were used by Urban jurgensen, Jean pierre hagmann and Antoine Preziuso who weirdly used it in a few wristwatches as well.

Patek Philippe Tourbillon Observatoire. A curious ressemblance...
The Patek: And now, the Cal 170 from Jaeger Lecoultre, which won several chronometry contests in the late 40's... Interesting. Best, Nicolas ...
In what era was this type of finishing common/expected in a 'nice' watch?
...'50s? '60s? '70s? Never?
What I thought but good to get confirmation...
...this is why vintage is soooo intriguing.
what a beauty!!!!!!!
Thats for me reason enough to buy a jacket, that has a pocket for a pocket watch
Same movement supplied to PP and VC, if I recall...
the VC 145, I think, but I could be wrong. Interesting that JLC added 3 jewels. I hadn't seen any examples of JLC's tourbillon in a Patek. Thanks for showing. -Dean

No.
Bornand made it himself not using any base. He also constructed the caliber 34T for patek
