I'm new to vintage watches. I recently purchased a few Swiss and German watches produced approximately between 1935 and 1965. Some of these watches were "new old stock" and others seem to have received very little use. So, they came with what seems to be the original leather straps.
It is not a surprise that the leather is a bit brittle from age. However, the straps also appear to be very thin and sometimes also short (as compared to more modern watches).
Is it likely that I am noticing a symptom of age and that the leather would have been thicker when new? Or, were watch bands different at that time? I guess another possibility is that these were inexpensive watches with cheap bands. Who can enlighten me? What do well preserved mid-century leather watch straps look like?
