Seth Thomas Mantel Clock Santos Brazilian Onyx

Beautiful antique Seth Thomas Santos model mantel clock with a wonderful Brazilian Onyx finish. Great Art Nouveau look with goldtone metal decoration, four columns and stepped base. The clock face is under glass with goldtone frame and shows some age darkening and paint flaking but looks nice overall. There were instructions/information on back panel, but the paper is mostly gone now. I don’t have a key, so I can’t wind it, but attaching the pendulum and pulling it back does make it work and tick for a few minutes until it stops swinging. It does bong on the half hour. I believe the pendulum is original. Clock housing looks great and is in really nice vintage condition overall with a few nicks — most notable is the one at top right on the edge of the curved piece at top. The finish makes it hard to see but it’s visible in the first photo. About 15″ wide x 13″ high x 6 1/2 deep.
