Hi Everyone, I'm new here and this is one of my recent watches. It's a Ulysse Narden USA Corp of Engineers watch. It's in pretty good shape and keeps good time. The case is coin silver (.800) and it is #7201. The case is 139571 and the serial # is 314982. Would anyone know when it was made? I've heard conflicting stories, that it's from WW1, then WW2. What would a watch like this be used for in the military? Would the dial originally have been painted in radium? It's kind of gold colored, now and doesn't glow in the dark. To tell the truth, I bought it because my father was in the Corp of Engineers in Korea and I'm going to give it to him as a Christmas present and I'd like to know a bit about it. Thanks.
