I saw an original Harrison longcase two weeks ogo, at Nostell Priory, near Wakefiekd, Yorkshire, UK. When the guide pointed this out I was elated, but the clock had stopped ! - "I dont recall it stopping before, she said, but the lady that winds the clocks comes every Wednesday at 3pm to wind it" ! - It WAS Wednesday !! and it was 2.40pm " She came, wound it, , set it to the right time, and set it going. This clock was made in 1717 and still performs like new !
While it is true that the Nostell Priory clock has a Harrison movement, it is not of the 'regulator' type but has a conventional pendulum and 'anchor' escapement, and is akin to the 1713 movement illustrated in the video. I also understand that the case of the Nostell Priory clock may also not be original. The only genuine Harrison wooden movement 'regulator' on public display is in the Clockmakers Company Museum in London where it is displayed along with a restored 'regulator' movement.
2023 and I celebrate the 250th anniversary... Longitude Prize money In 1773, 80 years old English clock maker John Harrison was awarded the final amount of Prize money for his " seawatch n° 1 " H4 clock which solved the Longitude problem. Harrison had been working half a century to perfect his watches . A time of sextants and clocks, while today's rise of technology has isolated us from the natural World, unfortunately much to our detriment. #Longitude #MoonwatchUniverse
