What is this type of fastening called and what does it fasten to? Answered
This belonged to my grandmother (the clasp looks post 1930). I assume there would have been some kind of hinged cover over the watch face (a hinge and catch are circled). I don't know what the double fanged clip like thing on the back is called or what it is for. The double 'fangs' look somewhat like an upholstery pin. Given that the front is a watch, and one needs to see a watch for it to be useful.... what would this be stuck into or clipped onto? Anyone familiar with this style?
