I own a beautiful White Prince jump hour Bulova, but unfortunately, my watch repairman cannot find a replacement for the broken jump spring for the hour wheel. I realize it's a bit of a longshot to ask for one here, but figure it can't hurt. The movement is a 10AT, 15 jewels.
Secondarily, I might also be interested in an original hour wheel. The one on my watch is a reproduction, which is fine, but if someone has an original that they're willing to part with, I'd be interested. Of course, this is somewhat moot, if I can't find a jump spring.
