The Models 8 and 9
1904 to 1913
The New Eagle Series was yet another 3/4-plate design, starting where the Old line left off, and again the two models were mirror images for hunter and open-face. The reasons for the change are unclear, but these newer versions were more accurate watches. The Model 8 and Model 9 were nearly identical to their respective forebears, but with two differences - the balance bridge alignment pins were inverted, and they were thinner, allowing them to fit into the factory cases. Jewel choices were still 7 up to 17 and the plate finishes remained the same.

Travel Clock
Seth Thomas offered a simple 7-jewel travel clock containing either a Model 6 with a flat hairspring or a Model 8 with a Breguet hairspring in a leather-wrapped metal case that was available in several color choices. The factory listed its top-grain leathers as lizard, alligator and seal with second-quality hides of pig and morocco in half a dozen colors.
It's assumed that the button on the upper left side of the case is to set the hands, but no pin-set Seth Thomas models are known to exist. Lever-set variants placed the lever in the standard 12-minute location and pendant-set mechanisms occupy the same position under the dial, so it's a mystery why the setting button is on the left. The company could've used a standard pendant-set movement, since the crown is visible in the ad cut and easily accessible.
