LeCoultre Reverso - help me identify

[golo]

I need help to identify the age of this watch. Could anyone tell me if it's an american or european one. When it was build ?
Thank You very much for help !

There were no US market Reverso watches, the patent was shared with Hamiltion to serve the north american market.
The gap between case serial and movement serial seems a bit too wide, movement was produced about 1935/36.

Thank You very much for fast answer ! The movement and the case doesn't match ??
So about what year could the case be ? Is it older or younger than movement ?
Kind regards !

I would date the case a bit older like 1932/33 but there is no tracking data, just educated guessing.
