I was wondering if anybody could give me some information about this old stopwatch? The logo looks like either an H or an N over an S. There is a print stating "Famdewe Berlin W 30" but it almost looks like it was added at a later point. At the bottom you can see "Made in Switzerland". This is a photo I took years ago. If needed I can take some better ones, also some that show the back (winder, some sort of adjustment setting, and a serial number). Thank you.
