Hi,
How is the automatic mainspring build up?
Is the Safety spring just one part (spring slightly smaller then the circumference of the barrel) that alows the mainspring to slip when overwound?
If so is the mainspring then just a normal mainspringspring with a normal (as in hand-wound) bridle?
If've read the Bulova self-winding watch manual but this isn't that clear to me.
Thanks in advance
Regards
