Classicwatch Vintage Watches

Bought this nice pocket watch movement for casing and found "LeCoultre&Co" stamped in the bottom of the barrel bridge.
Serial numbe in the main plate on the dial side is: 91634
Number "2" is stamped on the bottom of all bridges and on the main plate at the dial side.

Any information about the movement would be appreciated. Date of manufacture, calibre number... maybe a catalogue picture or a reference.
It is an ebauche, what manufacturer bought this from LeCoultre?

Thank You!

I don't have any catalogs that go back to ear bar style movements like what you have. It's going to be difficult to identify.

A whole set of manufacturers could have bought it. This is from the era where LeCoultre has a ebauche supplier they probably didn't even have their own line of watches.
