This is a Hamilton Sangamo Synchronous table clock set in green alabaster marble. It has an Art Deco style to the face, which includes a “floating” small diamond second hand; very neat to watch when the clock is plugged in. There are two black rectangular panels on either side of the clock that are I believe either a hard composite material or bakelite. The clock runs fine; you have to follow the instructions on the back to start the mechanism. There is a chip about 1/2 on the front of the clock as shown in the close-up photo. The clock measures 7 1/4″ tall, 5 3/4″ wide, 2 1/2 deep and weighs just under 7 1/2 lbs. Vintage ART DECO HAMILTON Sangamo Synchronous Table Clock Alabaster Marble.
