Note: year of production wrong has been in my familey
since 1924 and have bill for purchase dated
3/1/1924 also shows the grade as railroad
Curator Response: As noted within the lookup information help guides, the production year is an estimation, generally accurate within +/- 3 years. This watch would not have qualified for railroad service at the time of production.
