Today I'm sporting a Denison cushion cased Rone Sportsman 15 jewel with bags of character most probably from the late forties or early fifties.
This had been lying for quite a while in the to-do pile, as I had assumed that since it was locked up solid and had a distinct rattle, it would have a broken balance. Fortunately this was not the case, and all it needed was a thorough clean and now it is ticking away quietly. It is sitting around +10 sec/day, all be it with a relatively low swing around 220 degrees (a slightly tired mainspring most likely) but a more healthy beat error of 0.6ms.
The diminutive size of this Gents watch is quite a contrast with the recent trend for wrist mounted frying pans.
I had no suitable strap for it so I had to improvise from one of the straps in the scrap pile.
Hi might have to pop it out of the case again. might as you say be a snail cam problem as the rack tail has may be landed on the 5 step or the rack lock when it counts it back has not held and slipped one but I would think that would have affected more than just that need to see the front plate with all the levers.
Figured the pushers out.The silver part is the inner piece on the inside of the case. The brass piece with the o-ring is the outer part that gets pushed. Obviously the spring sits in between. The silver end is a tube that pressure fits over the outer piece. Has a knob like end that keeps it from slipping through the sleeve insert, which has a large diameter on the outside and a smaller diameter on the inside. That also keeps the spring retained between the 2 pieces.
Sorry for the poor quality.
