Seth Thomas Adamantine Clocks

From 1860 through 1870 clocks imported from Europe with decorative slate, onyx or marble cases became very popular among the purchasers in the United States. Clocks of this style became a status purchase among the wealthy.

In 1882 Seth Thomas partnered with The Celluloid Manufacturing Company of New York City and started using a new material called Adamantine which was a celluloid veneer in a wide variety of colors that simulate marble or alabaster. This new material made the clock appear like many of the more expensive clocks imported from Europe, but would sell at a price most families could afford.

Adamantine veneer was developed by the Celluloid Manufacturing Company of New York City, and was covered by U.S. Patent number 232,037, dated September 7, 1880. Seth Thomas Clock Company purchased the right to use the Adamantine veneer in 1881.

  1. I have a Seth Thomas Adamantine mantel clock. It was my great-great grandfather’s. I was told in 2012 by a clock repair man in TX that it cost about $7.00 new and is worth about $300.00 now. It has the key with it. There is a little damage on one of the columns. It’s been very interesting learning things about this clock. Thank you
