Excellent condition for its age. This is a vintage advertising Bubble Up Illuminated clock manufactured by PAM Clock Co., New Rochelle, N.Y. dated 1962. The domed glass and glass face with reverse printing are in very good condition. I have been running the cooler LED bulbs in this clock for the last 10 years to preserve the paint on the back of the face (less heat than incandescent bulbs).
Keeps very good time, this clock has been hanging in my office for the last 35 years so there is no rust or oxidation.
Face diameter is 14-1/4"
