First post here, I am a collector of vintage watches for about 8 years and JLC has been the first brand I bought with a Powermatic from the 50s with a Türler dial. This watch is still in my possession today and as definitely something special for me. I developed my collection and get 2 memovox, 1 manual and 1 automatic.
This beautiful LeCoultre Memovox Automatic in gold 10k has been produced for the US and I am trying to have a better idea of how old is this watch please? Would anyone have a table of serial / year to help me get an idea of which year this watch is coming from?
Here is a picture of the movement and its serial is 1710240

and here is the watch:


Thanks a lot for your help !
