Seth Thomas Pocket Watch Models 10 - 13
Seth Thomas Century Series is represented in the Ehrhardt American Numbered Drawings as Model 10 EA 813 (top left), Model 11 EA 814 (top right), Model 12 EA 813C (bottom left), and Model 13 EA 814A (bottom right); and can be identified through the use of the drawings below:
Model 10 and Model 11 are grouped together as they were presented in the 1904 Seth Thomas Watch Material Catalog No. 650 as the Century Old Model. None of the Model 10 nor Model 11 movements are numbered on the top plate. They were all manufactured as lever set movements, with either a gilt or nickel finish, 7 jewels, a plain/simple regulator, and a flat hairspring. They were the original Seth Thomas factory named grade Century movements.

Model 10 open-face movements were manufactured with a gilt finish or nickel finish and 7 jewels, a plain/simple regulator, and flat hairspring at Seth Thomas factory named grade Century [*1.g].
Model 11 hunting orientation movements were manufactured with a gilt finish or nickel finish and 7 jewels, a plain/simple regulator, and flat hairspring at Seth Thomas factory named grade Century [*1.g].
Model 12 and Model 13 are grouped together because Models 12 and 13, the New Century Models, were the replacement for and based closely upon the design of Models 10 and 11, the Old Century Models. Models 12 and 13 movements initially (1903-1904) had no serial numbers on the top plate just as none of the previous Model 10 or Model 11 movements had any serial numbers on the top plate [ *1.g ]. Despite there being partial serial numbers on the pillar plate of their mechanisms, there is currently no reliable way to state exactly which early “un-numbered” Model 12 and 13 movements were manufactured before any others.
The New Century Model 12 and Model 13 movements are thinner and have smaller balance bridges than the Old Century Model 10 and Model 11 movements [ *1.g ].
Model 12 open-face movements were manufactured as lever set or pendant set, with a gilt, nickel, or two-tone finish and 7 jewels, and flat hairspring at Seth Thomas factory named grade Century [*1.g].
Model 13 hunting orientation movements were manufactured as lever set, with a gilt, nickel, or two-tone finish and 7 jewels, and flat hairspring at Seth Thomas factory named grade Century [*1.g].
