About Us

Mechanical watches and clocks convey the art, science, engineering, and history of our culture, guiding us through the passage of time, and marking the progression of our lives from generation to generation. They tell time by using the energy from our very being and give it back with precision and beauty. My name is Eric Greenberg and ClockSavant represents the culmination of my obsession with time, spanning a period of over 25 years. 

As a collector, watchmaker, and clockmaker, I have crafted this company to combine the best of everything horological for the benefit of our customers.  This website, the services we provide, and timepieces we offer maximize the joy of quality mechanical watches and clocks, the history of past generations, the sharing of mechanical timekeeping with future generations, and are intended to provide education, trust, and assurance in our offerings.  

Eric Greenberg and prominent French watchmaker Colin de Tonnnac were interviewed by Brendan Cunningham for Time+Tide, one of the world’s leading publishers of watch content. Read the article here.
