Up for auction is a running antique 16S South Bend railroad grade pocket watch in a very nice gold filled Nawco Challenge case. The Challenge case shows very little wear with no brassing - just a real nice case. The serial number on this South Bend movement is 892214 and this movement is a grade 227, model 2, 21 jewels, pendent wind, lever set, adjusted to temp and 5 positions, railroad grade, and it was manufactured in 1918. I will gladly answer any questions and thanks for looking.
