    ?? Seth Thomas is well known for their "Adamantine" black mantel clocks, which were made starting in 1882. Adamantine is a celluloid veneer, glued to the wood case. Adamantine veneer was made in black and white, and in colored patterns such as wood grain, onyx and marble.

      Hello Spivey 85
      Welcome to Collectors Weekly, Clocks!
      What you have here is a Sessions Black Mantel Clock. Seth Thomas was a different company all together. Seth Thomas made clocks with the "Adamantine" celluloid veneer, and it was patented, so no other clock company could offer it.
      There is a good write up on the Sessions Clock Company on this website at the following link:

      Like many of the other American Clock manufacturers of their time, Sessions used a hard black enamel finish over their wood cases. It was a pretty tough finish and many examples have held up pretty well over time considering these clocks were made in the early 1900's.

      You clock model is the Sessions "Brewster" from circa 1923. Your example could have been manufactured and sold several years before or after that date. It was described in the Sessions catalog as follows: "Brewster -1923 15 inches log. 10 1/2 inches high. Bronze Metal Trimmings. Gilt Metal Caps and Bases. Five inch Arabick Iveroid Dial. Convex Glass. Eight-Day. Cathedral Gong Half-Hour Strike on Cup Bell."

      Here's another similar example that was posted on Collectors Weekly a short while back:

      Sessions did release this same clock as the "Marigold" about two years later in 1925. Here's another online example:

      So, without additional information (label or definitive date) your clock could have been called the "Brewster" or the "Marigold" depending upon the date it was made and sold.

      I hope that solves your mystery. If so, please consider marking your posting as "Mystery Solved". If not, please let us know what other questions you may have.

      Again, welcome to Collectors weekly.

      Thanks for sharing with us.

      Wow... amazing, thank you so much Mr Bruce. I couldn't thank you enough. I've had this clock for about five or six years with hardly any information at all.

      You're very welcome Ms. Spivey.85. I'm glad that we were able to provide some information on your clock. There are thousands upon thousands of them out there and we can't identify some. You have a nice clock and I don't see a lot of other examples online. Thanks again for sharing with us. Hope to see you around. There's a lot for collectors to see and enjoy on this site.
      Take good care.
