H4
This is the most important timekeeper ever made. It is the machine that solved the problem of keeping accurate time at sea and finally won Harrison the Longitude Prize.
H4's high-energy watch balance was less affected by the movement of a ship and was the design breakthrough that Harrison needed. He believed his fourth timekeeper was the most perfect and beautiful machine ever constructed.
H4's predecessors H1, H2 and H3 are also on display in the new galleries.
