Charles O Terwilliger, Jr.

Charles Terwilliger’s contribution to horology can best be described as innovative and colorful. Not only did he revolutionize the accuracy of the 400-Day Clock, his research and clock reproductions continue to impact the world of clock collecting to this day.

HeroesofHorology.com was established in 2025 to honor the memory of Charles O Terwilliger, Jr and the company he established, Horolovar, and to fulfill the dream of his son, Robert Terwilliger, who wished for this biography to continue on after he himself passed away.
