In the midst of Elgin and Waltham introducing new lines of extra-thin watches, the E. Howard Watch Company also launched a competing line.
In December 1907, under the management of the Keystone Watch Case Company, E. Howard began advertising the new line with a 12-Size open-face bridge-model movement and exposed stop work.
One of the primary distinguishing characteristics was that the watch was fitted with a white enamel dial, contrasting the new metal dials used on Waltham’s Colonial Series at the time.
Three grades were offered by the company: “Series 8” (21 Jewels, Adjusted to Five Positions, Temperature, and Isochronism), “Series 6” (19 Jewels, Adjusted to Five Positions, Temperature, and Isochronism), and “Series 7” (17 Jewels, Adjusted to Three Positions, Temperature, and Isochronism). The complete watches were delivered from the factory in solid gold or gold-filled cases.
