Serial Number 3902083 was reported as inaccurate.

Note: I have a Waltham 6s Seaside S/N: 3865255 one on
eBay 3902083 that according to the Waltham Watch
Material catalogue for 1911 it looks like a Model
1889 and nothing like the 1873-6. Sure is
confusing. I seriously question the Model number
accuracy of the database.

Curator Response: Thanks for the report. The Waltham factory serial lists designate this run as a 6-Size, Model 1873, Seaside Grade. It is crucial to understand the limitations of original factory documentation which is known to contain errors due to company practices. It should also be noted that the factory serial lists indicate the first run of Model 1889 does not occur until 4,044,001-4,046,000, though an earlier run would not be surprising. An eBay item number would be beneficial to evaluate this particular example further. (You have also listed two different serial numbers in your report).
