The photo is so poor and blurry, it's really hard to be certain of anything. See if you can post some good clear from various angles. Including any serial numbers on case and movement.
Looks like an early 1950’s model. Unfortunately, it was redialled a long time ago. Movement is probably a cal. 480, which is very well made and will run accurately for years once serviced.
Serial number on the case is useless, as it is a U.S. made part. Should say something like “Cased and timed in USA by LeCoultre” inside.
