The Beginning Of The Clock Doctor

Clock Doctor
Bill & Tyler Gesswein

The collection and appreciation for mechanically driven time keeping devices is called Horology. For The Clock Doctor, the horological journey began in 1960 with owner Bill Gesswein Sr. purchasing a clock that was not running and teaching himself how to fix it. After some disassembly, and the clock coming apart in many pieces, his interest was piqued and he had his mind set on learning the craft.

While serving in the United States Air Force in Bitburg, Germany, Bill and a friend opened a clock shop; five years later Bill was transferred to Denver, Colorado and brought the clock shop with him. For 18 years Bill ran his clock shop in Denver until deciding to move to Scottsdale, Arizona where The Clock Doctor is now located.
