Of international scientific importance, the Harrison Clock is only one of only three precision pendulum clocks made by John Harrison and instrumental in solving the Longitude problem. The clock was made in 1727 with an amazing fully working wooden mechanism. Plans are in place to display it as part of an interpretive display at Leeds City Museum.

With thanks to the BBC

After almost 40 years at sea iā€™m now retired. 3 weeks ago i climbed the stairs up to the Royal observatory at Greenwich. Came all the way from my small town in Norway to tick off one of the items on my bucket list; To see with my own eyes the clocks of John Harrison. Not the sole purpose of my visit to London but still an emotional moment

Wow! This was astonishing in so many ways!! The level of skill used with the different woods & his knowledge of how they dry, how oily, theyā€™ll continue to be, etc is mind blowing!! These men were astute on so many levels!! I would love to know what his schooling was & what their father did for a living. This is an amazing story!! Thank you for creating & sharing it!!

I am from near Boston, Massachusetts USA. The family of my best childhood friend had an old tall case clock (grandfather clock) that had wooden clockworks. To keep it lubricated, a small saucer of kerosene was placed up in the clockworks portion. The vapors kept everything lubricated.

Many thanks for sharing this. I do not own a TV set and have been persecuted by the BBC for five years to purchase a TV licence. They cannot believe l don't own or rent one. Even just to watch iplayer you still need a licence, the grasping front and back studs! So this is a treat to watch something from them for free!

John Harrison is an unsung hero to whom a vast number of sea-farers owe their lives. I am one of them. We used his chronometers in the 1950ā€™s to keep track of the position of my US Navy destroyer in the Pacific Ocean. Harrisonā€™s education was limited; his energy boundless. The book, ā€œLongitudeā€ by Dava Sobel celebrated his struggles with the bureaucracy and was made into a TV series well worth watching.

I read the book about longitude, great book. The true reason the board did not want to give him the money was because he was a lower class commoner NOT like the board who were all upper class and wanted one of THEIR own class to win.

The segment where they threw the tin can over the back of the boat (they did mention the log) was actually carried out with a log of a set size. This was known as the captains log and was carried out every hour to measure the number of ā€œknotsā€ that the ship was travelling at. Our phrases now for ā€œkeeping a logā€ and ā€œlogging onā€ come from this.

Can't stop thinking about the Harrison Clock auction room scene in 'Only Fools and Horses'...

Here in America most of the kids cannot read a clock with hands. I adopted three from foster care and their argument was they have cell phones and so do not need to know how to tell time. It is now three years later and they are all doing pretty well.

As a clockmaker myself it is so refreshing to hear a man who actually knows the meaning of the word "cogs" (11.26)

John Harrison is one of VERY few real-world cases where a lone genius legitimately revolutionized their entire field.

Seems like it's the simple folk that impact the world most with their inventions, like Mr. Harrison and the Wright brothers. Very interesting. Thanks for posting.

I saw a Harrison clock once. It was a replica, but it had been made in the same way as the original. It was an amazing piece of art.
