Antique Elgin Dueber pocket watch. I am not an expert in pocket watches but I will do my best and have listed many of photos for you to see. The watch measures 2 1/4" in diameter. It is marked Dueber and 925 for sterling mark inside the dust cover. The watch in in working order. The engraved case is a little worn especially around the case rim but it does have a nice patina. We date the watch to 1903.
