Japanese Clock Logos

This site will concentrate on the Japanese Industrial Clock Manufacturing Industry that started in the 1880's and disappeared when electric clocks flooded the market.

Charlie Davis got hooked on Japanese clocks when he taught his first clock repair class soon after joining the NAWCC in 1968. They proved the ideal vehicle to introduce newcomers to owning and repairing clocks--plentiful, cheap and badly in need of overhauling! Since then he has handled hundreds of them and his curiosity grew about the story of those clocks. Charlie Davis

How to find and identify your Japanese clock logo?

a. There are four broad classifications:
      1. Roman letters (Axx-Zxx)
      2. Japanese (Kanji) characters (JCHxx)
      3. Living organisms (ANMxx), and
      4. Drawings of objects and shapes (OBJ).
b. Except for roman letters, each classification is arranged assigned with numbers loosely based on accession.
c. For roman letters, use either the initial letter of the name or select the letter that appears FIRST in the alphabet.
d. Since logos do not always appear in exactly the same way and might fit different classifications, the process might require searching several locations.
