Hi all, I've picked up an old 20s / 30s pocket watch and have given it a strip and clean to find it runs well. My problem is the winding pinion is stripped therefore can't be wound via the normal method. I'm struggling to identify the maker and caliber and wondered if anyone here might be able to help? I'll attach photos as soon as I work out how. Some info. It's 16 - 16.5''' and I'm assuming either Cortebert or Thommen. All the bridges and plates are stamped with either 868 or 898 (depending which way round you're looking at it)
Thanks in advance!
