The Double Bubble clocks, were made from the 1940's to the 1960's and were known for being the most attractive of all the advertising clocks. Coca-Cola clocks like this might have adorned the local hardware store, bicycle departments, or repair shops.
The clocks get their nickname Double Bubble because there is an inner crystal or glass bubble which displays the company logo. The hands of the clock are sandwiched between an outer crystal or glass bubble which usually displays the numbers of the clock. Domed glass over the front helps to float the hands above the Classic glassed-in Coca-Cola logo.
Each clock lights up with two 7 1/2 watt bulbs that are included.DOUBLE BUBBLE CLOCK SPECIFICATIONS:
