Here’s another classic tambour mantel clock by Seth Thomas, this one in a dark mahogany case. The dial is a brass sheet with embossed numerals, lettering and time track that has been matte silver plated. The hands are the modern “ST” pattern (S on the minute hand and T on the hour hand).
The 8-day No. 89 movement strikes the hour and half-hour on a cathedral (heavy flat wire) gong.
The case is 9 3/16 inches tall and 16 3/4 inches wide. The dial’s minute track is 4 1/2 inches in diameter, and the minute hand is 2 5/16 inches long.
The original mainsprings have the following measurements:
- Time mainspring: 3/4 inch wide x 0.016 inch thick;
- Strike mainspring: 3/4 inch wide x 0.0159 inch thick.
Repair job 5740. Polish pivots, install 16 bushings.
