Pocket watch caliber

BlueHarp · May 24

Hi again,

I've got a pocket watch in very bad condition, but the movement started again after disassembling / cleaning / reassembling, and it works pretty well for an old caliber. The thing is: I can't identify it. No indication of a name, no logo, only a serial number.

I've tried to use Bestfit for the idendification, but without result. The diameter is 35,6mm (dial side) and 35,5mm (back side).

Maybe is it one of those calibers made by the farmers in Jura during wintertime? There used to be a tradition for farmers in that eastern part of France to work for watch manufacturers in winter time because they had less work in the fields.
