This is a new old stock gents "sex" watch with a mechanical Swiss movement our store purchased sometime in the 1970's-1980's and was not sold ( No Previous Owner). The watch has original plastic pouch however, it does not have paperwork.  There is a small scuff mark on the outside bezel by the four o'clock. The square case  is 43mm by 45mm with a white colored 30mm dial. The rubber strap is black colored with 18mm lugs. The watch will fit 8" wrist when the  buckle is affixed to the second to the last hole. The movement has recently been oiled and runs great. An excellent, unique novelty watch for that special collection!
