I decided to put my "unlucky" Jaz Derby Swissonic on Ebay. The movement works, but the cylinders don't roll and time doesn't advance. I don't know what could be the reason of this problem... The watch is in very good conditions so I hope it can come in handy to someone for spare parts, as it's only a paperweight to me.
Here's the link of the auction:
