Restoring the Simplest Chronograph from Omega: The Chronostop Watch Cal 865

I am a big fan of Omega watches and chronographs in particular. I always wanted to add an Omega Chronostop watch in my collection and I managed to find a cheap exemple on eBay that needed some work. I will try to restore this watch with the famous caliber 865. Hopefully it will be a nice watch to add to my collection after the restoration.
