Vintage Helbros Automatic Watch Resto-Mod: Hidden 25J Upgrade From A Donor Watch! PUW 1463

In this video, I’m working on a beautiful vintage 1970s Helbros Day-Date automatic watch made in West Germany. This watch originally featured a standard 17-jewel automatic movement, but I managed to source an identical caliber donor watch that featured a factory 25-jewel upgrade! Watch as I break down the cushion-case timepiece and upgrade the movement/automatic works to the premium 25-jewel version for better reliability, smoother efficiency, and longevity.
