Elgin has made some great clocks. This one is a cylindrical rotating tube that measures 3-1/2” in height and 3” in diameter. The primary color scheme is gold, brown, and black. The base is plastic but made to look like wood and features the “ELGIN” name prominently in gold.
The remainder of the clock has a transparent housing topped with a transparent, grooved cap that has an etched spiral pattern in gold on the top.
Here is the winding and time setting mechanism. The clock has a Japan made movement.
