Seth Thomas Green and Black Adamantine Mantel Clock, Rear Escapement

May 30, 2011 | By | Reply More

This beautiful Seth Thomas green and black Adamantine mantel clock has the older type of movement with rear escapement. See my clockhistory.com web site for some history of Seth Thomas Adamantine clocks. This clock is 11 3/8 inches wide and 12 1/2 inches tall. The dial is not original, and has a 4 1/4 inch minute track.

The time click was broken in two when this clock came in for repair. The strike click was a previous replacement that was located incorrectly. I installed two new clicks, and the original wire clicksprings were in good condition. I also polished the pivots, installed 12 bushings, and replaced the wires in the escape wheel pinion.

The mainsprings appeared original, the time spring measuring 11/16 x 0.0175 inch, and the strike spring measuring 11/16 by 0.0183 inch. They were in good condition and so were retained in the clock. If they needed replacing, I would have used thinner ones, 0.0165 inch thick.
