This is an antique Swiss-made Cletimer single-jewel hand-wound stopwatch that still works like new when wound up. I came across several of these watches just before they were going to be thrown out at Wabash College . The college had no use for them and was going to throw them out, and I was able to take them knowing their intrinsic value. This is one of two that I am selling; it is in great condition considering its age and use. T is a little wear visible on the back w the chrome has begun to come off. These are rare watches, and if you are a watch collector, please enjoy.
