John Harrison's H1 chronometer. A wooden working replica
A 3/4 scale model of John Harrison's first sea clock of 1735 known as H1. It is made largely in wood and retains many of the innovative features in his original clock that made it the wonder of the age and led on to the development of his other clocks. His 4th timepiece satisfied the Board of Longitude that its accuracy was sufficient to find longitude at sea and thus qualify for the £20,000 prize.
