I have some old Omega wristwatches with this movement. It seems like a 37.5T1 but it's not, and this is much older, i'm sure. Can somebody help?
I think these were originally (ladies?)pocket watches converted to wristwatch during or after WWII, both case are custom made without Omega stamps, except the dials and of course the movements. The other one is silver cased and both are around 40mm.
