Note: It's Railroad grade. I have a sister to it made
on Sept. 1910. that was worn by my grandfather on
the railroad for 40 yrs .
Curator Response: Thanks for the information. Could you confirm the watch is lever-set? This is the reason it has not been identified as railroad grade in the database yet.
