here is a interesting Hampden i picked up at the flea market sat. for a few dollars..

I think this is a interesing watch it is a 2 button 17 jewel chronograph with a 30 minute register,,works great

very interesting movement i like to watch it work

i spend 10 minutes last night just watching it..

Samie,

That's 100% Valjoux. A very rugged and reliable movement and the now predominant 7750 is a direct descendant. Nice find!
