Christopher Ward is releasing the C9 Harrison series of three automatic watches to mark the 250th anniversary of John Harrison’s invention of the H4 pocket chronometer in 1760.
Edmond Halley – of Halley’s Comet fame – was another champion from the time when Harrison first proposed his solution.

He solved the problem by using
different metals in the movement that expanded and contracted in complementary measures and by doing away with the need for unstable lubricants through the use of his own invention of the grasshopper escapement.
