hmm... i think we need a better closeup of the dial (more in focus)... also, is there any way to see in the sides? is there a back panel that comes off and exposes the movement? we need to see behind the curtain (dial)... if there's a way to get photos of the movement that would be a big help in identifying what you have.
also, the glass can be replaced... a photos of the inside of the bezel that shows any clips that might have held the glass in place would help.
Wuersch was a clock builder (note I didn't say "maker" as he did not make his own movements) in Fall River in the 60's through the early 80's. He used Hermle clock movements and built his own style cases. As I understand it, he came to the US and started his business, but later closed for failure to pay taxes. The finish on the case looks like stain with no varnish, which indicates either it was refinished or someone else may have built it and used a leftover Wuersch dial.
