Here is a vintage Waltham watch from a local collectors estate. This has a brass train on the back. This weighs 5.7 oz. The stem is at # 3 as shown. I see no way to set the time on this. I see 185402  SILVERODE on the inside back cover. I see 14748941 on the works. Overall a nice old watch for your collection. Please see pictures and ask questions. I will combine shipping. I usually ship the next day after payment 5 days a week.
