Here is another cool 3800J that's a part of my collection - not the "holy grail of 3800s" I've referred to before but still pretty special. The watch was retailed by Gubelin in 1984 which I managed to have confirmed through Gubelin's extract services (highly recommend it if you have a watch from them, the certificates are beautiful and their service is great) as the papers and box of the watch were misplaced by the original owner.
Enjoy !
