I picked up this little Waltham trench watch on ebay a number of days ago on impulse. The condition caught my eye, but I am not terribly familiar with vintage watches such as these. However, from what I understand, it dates back to the early 1900s and has been disassembled and oiled. It's running very well and fairly accurately at +/-60 seconds a day. I am not sure if the crown is original, but the dial and case appear to be original. I'm very curious on the history of pieces like these so any other information you guys may have on this watch would be greatly appreciated!
