Erwin Pearl watch

Stunning watch with a square face. Adorned with sparkling tiny diamond chips or crystals. Features a silver and white color scheme. it’s for an extremely tiny rest. It was given to me by a relative when I was very young and I definitely cannot use it now because of the size I found it in an old box that I had beautiful piece of costume jewelry I believe but I’m really not sure and I’m not gonna pay to have it appraised. It is an antique. Offers welcome it’s in great condition. Please see pictures. Offers welcome.
