Take the movement out of the case. Move the minute hand manually for the warning and watch the rack drop, take note of where the gathering pallet engages the rack. The correct position for the snail should be for twelve o’clock it should be about, see red arrow. Forget the black ones. Try that first. Let me know.
Today I'm sporting a Denison cushion cased Rone Sportsmans 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.
