Hello, I'm trying to find the calibers for two watches I have, but no luck yet. One is an Omega from 1925 (give or take) and the other is a no-name pocket watch for which I'm trying to find the hands (all hands are missing). I uploaded the pictures below and any info will be welcomed. The Omega watch has a serial number, so thats how I got to the year 1925, but thats about it. The pocket watch doesn't have any signs, besides a serial number, so it's a bit hard to identify, at least for me.
