I had this forwarded to me, maybe some have already seen this though. But I was well impressed watching the video.

Fascinating video. At first glance it seems a bit Heath Robinson adding a penny to the pendulum to keep it in time but if it's worked for 160 years why change it? Smiley Happy

I find it absolutely fascinating in it's design and construction - using a mechanism from nearly 300 years ago with a modern and unique display of the passing of time.

 

There are other vids on that page which give some different perspectives

 

 

 

 

This is a BBC vid on the history of the John Harrison clock
