First post and its a request for help.
I've recently acquired an early porcelain dialed single button Chronograph but cannot identify the movement. I've checked images on the net but with no success. I'm hoping someone can help. Its actually not in too bad a condition and although its missing the button (a new one has been sourced and is one its way) the movement is actually running.
The only info to add is that there is a '36' stamped underneath the balance wheel if that means anything.
Any help would be appreciated.
