This wonderful Vintage wrist watch is Swiss Gruen Veri Thin. The top of the case is gold filled and measures 25 mm from left to right. The lugs are 18 mm. The dial is in great condition and in the center it has a large second hand used for a doctor checking your pulse. The movement is a 15 jewel and mechanical wind. It runs but didn't check it for time. The band which has some wear is made from English pigskin. It fits up to a 8" wrist.
