I’ve linked to work by ’31jewels’ on the WUS forum before (see here: https://sweep-hand.org/2012/05/26/some-great-8110a-restoration-work/), and now he’s worked on five divers (probably from the 1980s) with the 8200 movement. He does excellent work, often on what you might think were just junk watches! Please take a look here:
