Serial Number 7101813 was reported as inaccurate.

Note: 7101813 is a Vanguard with 21 Ruby Jewels and a
Canadian face.
I was under the impression that the manufacturing
date was 1894.
I further believe it is a Canadian RR watch. It
is still one of the most accurate watches that I
possess.
Curator Response: Thanks for the report. This range appears in the Waltham Serial Ledgers as being manufactured May 1896-April 1902, Size 6, designated for English export. If possible, please upload an image of the watch to your collection for further inspection.
