Antique Whitehall Hammond Art Deco Green Onyx Electric Clock. Here I have for sale is a beautiful Green Onyx with Horses, Horses are made of Bronze I believe? Clock measures Approx: 16 wide at the base. 11″ Tall Horses about 9″ from base. Just the Clock portion about 9 wide. Clock is in working condition. Synchronous movement, so you have to turn the dial to “make it go”. Horses are tarnished, One much more than the other. One of the feet, paw, HOOF has broken off. Have it and will send along.
