The museum is also home to John Harrison’s personal regulator clock ca. 1725 , made almost entirely of wood – including the movement. Correct within 1 second a month, this was the most accurate clock in the world for many years to come.

If you notice in the photo, there is a handwritten table of data. Harrison utilized  this data, probably written in his own hand (!) when testing his sea clocks.

A definite must see!

When we visited, we had reason to call upon the director and ask him to mediate a mystery we were investigating. Although befuddled by the request, he was polite and accommodating.

  1. I have enjoyed seeing your web site. I am working on a Gledhill-Brook Time Recorder with the Fusee movement. I have never worked on a fusee movement and am kind of causious. I would like to know more about the fusee workings. Is there a spring in the big barrel. I need to take it apart to clean it. Thank you. Tommy Chandler, (clockman@frontiernet.net)
