Serial Number 686319 was reported as inaccurate.

Note: My research and multiple other sources reflect a
1908 manufacture date, not 1911 - 1911 had a
serial number run in the 800,000s
Curator Response: Factory ledgers indicate your watch was finished within the last few days in 1910 and sold January 3, 1911. The source for your proposed 1908 date is incorrect.
