Managed to get a 1972 Longines Admiral to start ticking again. The watchmakers in Mumbai are unable to source me the right one. Works well and I love the unique shape of this one. I know the dial is a refinished one but that works for me. The only thing I am struggling with is the crown. There are whole lot of different ones on ebay and I just cant seem to figure out which one is the right one. Any help from the experts here will be greatly appreciated. I have attached a few pics of my watch. I am also attaching photos of a watch I picked from the internet - it seems to have the correct crown.
