NWOT Vintage Ladies Watch Bracelet

These watch straps fit vintage ladies watches. My father was a watchmaker and sold these to his customers in the 60’s and 70’s. My brother still runs the business after 64 years and we found this in an old cabinet. I have only 1 like this. The colour and rose gold were not as common as the black ones sold at the time. It is NWOT and in very good condition.
