I recently got this old GP. It's quite beat up, but the style is just really really nice .
I was wondering if any of you vintage maniacs know more about this movement.
It's signed '02' and below that '1121' on the barrel bridge. I haven't taken the thing apart yet, but will service it soon.
Dr Ranfft's database doesn't contain a caliber 02 for GP, however it does have a cal. 03 listed.
I'm guessing its some AS or maybe a Peseux, but its a caliber I don't recognize immediately.
