Hello. I am new to the forum and joined to hopefully call upon some people's wisdom when I come across things outside of my realm of knowledge. I recently picked up a non working watch and was hoping someone would be able to provide me with some information on it. It is a Didisheim "The Racer" non-magnetic stopwatch. It is 13J, adjusted 2 positions, and has a production # of 61236. Any info would be very much appreciated. These watches seem to be pretty rare, is that true?
