From the introduction:

“The Clockmakers’ Buying Guide is a where-to-buy-it directory compiled especially for clock repairmen – or anyone who makes or repairs clocks. It is an indispensable tool,
bringing together, for the first time, hundreds of resources in one convenient publication.
In addition to listing the range of clock materials available from large suppliers, the Guide specializes in the
lesser-known suppliers who can provide unusual and hard-to-find parts and services.”

Clockmakers’ Buying Guide: pdf format (8mb)

The guide included instructions detailing how to mail a supplier or service provider for information – no phone numbers. The guide was not a success and was eventually sold to the American Watchmaker’s Institute.

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.
