When did JLC start signing their crowns?

Hi there,

is there a clear cut answer to this question? From what I understand they started out NOT having signed crowns and eventually started signing them in XXXX.

What is XXXX? ;-)

XXXX is a rating for a very hard core pornigraphic movie.....other than that I assume it refers to 4 digit serials...but that's a guess

no, XXXX would be (for example) in 1962

Don't have my reference handy, but IIRC, it was in the early to mid-fifties. I do not believe there is a specific year.

Uh, I'm pretty sure Nobel Prize got the gist of your post despite it being in the style of an algebraic word problem, (which most kids despised!) 😜

I was going to make a joke about the crosshatch pattern on supercompressor crowns looking like XXXX, but now I see the humor meter is low in this thread so I'll abandon any attempts.

Oh, and there's very rarely a definitive answer to questions like in the original post. 🙁

And to complicate things there were crowns marked LeC for US watches and and JL crowns for ROW watches.

And crowns marked JL for Lecoultre in the US....

I always think of my time in Brisbane when reading "XXXX"... Or Discworld:

I don't know for U.S. Lecoultre, but concerning Jaeger-Lecoultre watches, based on my resource, signed crowns were introduced just after the launch of the "JL" logo, in 1960. It would mean that any signed crown on a Jaeger-Lecoultre watch issued before 1959 is a replacement crown. But I would be more careful on the "symmetric" statement that any JLC issued after 1960 must have a signed crown. First of all, the production of signed crowns for all models might have take some time. Moreover, we know for sure few JLC watches that were both produced a bit later and that did not have signed crown: e.g. The Master Mariner Deep Sea.

The LeC crowns generally predated the 1960 introduction of the "JL" logo, at least in the USA.

I'm sure there was some overlap at the beginning of the 1960's.
