Curator Response: Thanks for the report. The production years displayed are simply estimates based on serial number extrapolation, usually accurate within +/- 3 Years. This is especially true with the Keystone Howards, as no factory records detailing the serialized production survived. Based on your evidence, it is likely the watch was produced in 1909. If possible, upload images of the watch to the site to provide documentation for furture research, especially since this is currently an undefined run.
