Serial Number 1287957 was reported as inaccurate.

Note: I don't understand why this would not be rr
grade.Is it because of the number of positions?
Curator Response: Correct. During the era of production, American railroads required watches to be adjusted to 5 positions to qualify for service. The 978 is only adjusted to 3 positions.
