Vintage Art Deco Chelsea Elecronometer Clock Model VE. Diameter is 6 1/4 inches. Clock face diameter is 2 5/8 inches. Very nice condition working clock. There are a few scratches on the front and the knurled knob that fits on the end of the time changing stem is missing. The time can be adjusted by using a coated pair of pliers or hemostats to turn the dial. Clock can be heard running but I believe this is the normal sound they make.
