I posted recently about some funkiness going on with my mint Octagon Bullhead. The watch runs great, but seems to have randomly lost all its power reserve - once it's off my wrist, it's done in a couple hours.

Any thoughts?

What could cause such an immediate drop in power reserve while leaving accuracy and performance on-the-wrist unaffected?

Can these movements be hand-wound to charge the reserve?

Thanks,
Noah

Bummer! :-( Sounds like a broken mainspring to me.

Random after plenty of reserve and a week in a watch-box that it would get knocked out. I wouldn't expect it to have any power-reserve with a broken mainspring. I could imagine a kink or whatnot, which sometimes work themselves out with a good "smack".
I gave it a solid 70+ turns on the crown to see if a serious reserve could be charged.
Either way, is that something that can be serviced? Any 8110 love for servicing? :)

Bad-to-worse. The minute it's off my hand, it's kaput. Now I believe it could be the mainspring. Any ideas?
