Vintage Wittnauer 2520 Swiss Quartz Watch Employee Engraved No Strap Untested

Vintage Wittnauer 2520 Swiss Quartz Watch Employee Engraved No Strap Untested Measures about 1 & 3/8" x 1". Untested - not sure if it needs a new battery or if there is another issue. Marks, scratches and signs of wear. Some tarnish/discoloration. Large mark/stain to rear. No strap included. Engraving to the rear that was personalized to the previous owner. Preowned, sold as shown - I am unsure of material type(s) because of this. Pictures show different angles for you to review - while I attempt to note any defects, some tarnish/signs of wear may be visible that are not otherwise stated. If you have any questions please feel free to drop me a message.
