My granddad has long since passed away and the watch bug bit me fairly recently, so I asked my grandma if he had ever had any watches. With some digging, my grandma found some cool, old watches including a Gruen Veri-Thin, which was her Christmas present to him--engraved "12/25/'45." Among the watches was a Benrus that I can't identify. I took some pictures, and I was hoping someone might know something about it. Also, how hard are parts to come by for repairs? Any recommendations on a watchmaker to get it running again? Thanks!
