Serial Number 231213 was reported as inaccurate.

Note: Item is listed as Railroad grade; other details
are correct.
Curator Response: It has been debated whether this watch is Railroad grade or not since it is a hunting movement. During this era, some railroads allowed hunting watches, but most required open face.
