Hi Guys, I know this is the den of vintage Carrera but i'll ask for any help i can get. So i found this vintage JLC ref number 119394 that i am very interested in. Before i'll start haggling the price, i thought i'll do some homework first. Photo attached. What do you guys think ? My concerns are (in no particular order): 1. The crown and lugs shapes i think are okay. What bothers me is the case back. I looked at some vintage JLC before and this caseback is like nothing i've seen 2. The ref number. Usually its 1194...this one is 1193... Considering those two however, i am not an expert of vintage watch at all let alone vintage JLC. Oh by the way, the deal is watch only (without box and paper).
