I have to say that I know nothing about this model, which has obviously a 70's look...
You'd better contact JLC on their website, sending them a pic of your watch, and the ref number, and they will tell oyu all about your watch, my friend.
Sorry to not be more helpful fro you, my friend...
Welcome here, BTW!
Best.

Funny watch!
I think it was presented in 1980. But I am still looking after info...
