Hey all, I was hoping to get some advice re: a non-Omega trench watch. I know its not an Omega watch, but I am looking for general collector advice. I recently purchased this Waltham trench watch on Craigslist. Serial number dates the watch to 1907, I believe, and the engraving on the case back connects the watch to a former commander of the California National Guard who served with Pershing in the Mexican campaign and then in WW1. It clearly needs a service. The dial looks like it had the (likely radium?) lume removed at some point. What is better from a collector-preserve-the-watch-for-the-next-generation perspective? Have the numerals and hands re-lumed or leave as is? If the former, does anyone have any recommendations for a California based place that can do that?
