This is a Sterling Silver Watch Chain that Slides onto a Belt and Holds a Pocket Watch Securely in a Pocket. It is finely etched loop that is built to slide over a belt, hook on to the watch and put in your pocket for safe keeping. I suppose it could also be used for a key. This handsome watch holder measures 1 1/2" x 1/2" and has an attached chain that is 5 1/2" long with a cone shaped clasp that has 4 very tiny silver hallmarks on it. The front of the bar is etched with scrolls and flowers. It appears to be very old and I would guess it to be sometime after the turn of the last century 1900 - 1930.
