Hello, I'd like to get some information about a men's Longines "Gold Medal" watch. The only I know, according to a clockmaker, it's of the 50's. There's not inscriptions, only "Longines Gold Medal" in the dial and "10k gold filled" and "Use all proof wrench 1125" at the back. I'd like to get some information, year, value, etc. I posted this question for a weeks ago but I couldn't put pics of my watch, but now I have pics. I'm sorry the pics aren't so good, they were taken with a webcam, but you can see how the watch is.
Thanks in advanced,
