One method was to devise a clock which could withstand the motion of a ship and still maintain high accuracy. John Harrison and his brother James, who were originally carpenters, built a series of such clocks for test purposes and their first model was named "H.l" which was mainly made of wood and weighed some 72lb. It incorporated several revolutionary features, notably a "Grasshopper" escapement and 2 dumb-bell pendulums. Our clock is a modern version of H.1 - but weighing only 12lb (5.5kg). We have retained the "Grasshopper" escapement and the dumb-bell pendulums, and still use a special wood - Lignum Vitae - for the pallets. The drive is our own 8-day spring-wound movement. The clock is supplied complete with a mahogany base and wood framed glass case.
