Hi, I am looking for a Longines Winding Crown for a 12.68z Weems 1937 watch, and if possible a Glass Crystal, if I have to buy the crown with a stem that is OK, I am not doing the clean up myself so I guess I am making work for my friendly watchmaker. The Movement according the Longines serial number chart was made in 1935, it does not have a seconds hand stop and is a sweep center seconds hand style. It is presently fitted with a generic crown and plastic plexi. I would like to get rid of those and fit original equipment. Is there anyone that can help with this please? see the attached picture. I am in Queensland Australia.
