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.

Production totals for the New Eagle Series are a little under a quarter-million, blocked from SN 700,001 to 900,000, with none reported above SN 853,000, and the open-face Model 8 continuing on from SN 2,500,001 up to 2,593,000. The New Eagle watches were better timepieces than the Old Eagle line, since they had micro-regulators and Breguet (overcoil) hairsprings. Some of the earlier runs of the 17-jewel variants were marked Adjusted.   

The first known appearance of the New Eagle Series is in the 1904 catalog, overlapping with the exit of the Old Eagle Series. The nickel variants of the Model 8 continued to the end, appearing in the 1913 catalog. 

The Edgemere was a named grade, made by ​Seth Thomas for Sears & Roebuck in 6 and 18-size, with both models being offered in an unusual 12-jewel count - the upper plate was fully jeweled, while the pillar plate was bushed.
