I have a swiss watch. It is in the shape of a ball. The brand is marmon and it also has written on the front 17 jewel.It is a wind up watch that you wear like a necklace. It is truly a beauty you can see all of its working parts on the back side. I would like to know when and where or who it was made by.It is clearly an antique and im interested in finding out more about it. Has anyone ever seen or know of this watch?
