Serial Number 90789 was reported as inaccurate.

Note: seller says it is a RR watch
Curator Response: Your seller is incorrect. The "Commercial Standard" would not qualify for railroad service during this time nor was intended to be a railroad watch. The "Official Standard" watches were intended for railroad service.
