Serial Number 19397775 was reported as inaccurate.

Note: 1- The size is a 16 1/2 according to the Grey book
info. Not 17s that is listed.
2- The date of the watch is 1914 (not 1913) as
per Roy Ehrhardt's American Pocket Watches
encyclopedia and price guide and other Waltham
publications.
Curator Response: Thanks for the report. I will try to get the size updated. As for the estimated production year, all published date tables (from any source) are purely estimations unless source documents exist. These are usually accurate within +/- 3 years. Discrepancies within this tollerance are normal and to be expected.
