Mahogany Seth Thomas Adamantine Mantel Clock, 6 Celluloid Half Pillars

May 25, 2013 | By | 8 Replies More

I just repaired this beautiful Seth Thomas Adamantine mantel clock. The mahogany Adamantine finish is in excellent condition, and has not faded much, if at all. The 6 celluloid half-pillars are celluloid with metal bases and capitals. The paper dial has Arabic numerals. The movement is the popular and reliable No. 89C. The clock was made around 1905.

The case is 18 1/16 inches wide at the feet, and  11 1/32 inches tall. The dial’s minute track is 4 3/16 inches diameter, and the space minute hand is 2 1/8 inches long.

Time: 3/4 inch wide and 0.0172 inch thick

Strike: 3/4 inch wide and 0.0163 inch thick.
