This Adamantine mantel clock uses the no. 89C movement, and was made around 1901 - 1910.

“Adamantine” was Seth Thomas’ trademarked name for a celluloid finish over wood. Besides the mahogany color shown here, it was made in black, white, green, brown, tan and other colors. These cases are durable, and can usually be polished to look very nice. Sometimes the colors fade with age. Adamantine clocks were made from about the 1880s to the 1920s.

    Interesting - looks like my mahogany "Dana Number 4" with the addition of some side columns and a larger base. Mine has an 89 movement. Both the hours and the half hour are struck by the same hammer, on the gong. And both strikes are controlled by the countwheel. The date stamp on the bottom of mine is March, 1904
