The American tambour mantel clock was very popular in the 1920s and 1930s. This example by Seth Thomas is a classic that uses the reliable No. 89 movement. It strikes the hour and half hour and is an 8-day clock (intended to be wound every 7 days, but will often run 14 days on a winding).
The case is 9 1/4 inches tall and 19 1/2 inches wide. The dial is aluminum with printed markings. The minute track is 4 5/8 inches diameter, and the minute hand is 2 5/16 inches long.
The pendulum bob is 45.3 mm diameter, and weighs 5.4 ounces.
