Hello all! I am doing this because I couldn't find any detailed information on this caliber, except some general photos. So I sort of explored it. Yes, I was an explorer, so please forgive the clumsiness! This is going to be more of a parts list presentation then a proper tutorial. I don't know what the parts are named, but I will try to explain what most of them do, from my understanding. Also this is the first time I opened a chronograph-like mechanism. It is a 24 ligne (55mm!!) russ
