The ‘Grasshopper’ skeleton clock is based on the first marine chronometer made by one of the world’s most famous clock makers, John Harrison (1693-1776). Harrison spent years perfecting marine chronometers in order to win the prize offered under the Longitude Act (1714) of £20,000 for any invention capable of calculating longitude to within 30 miles. His original time-keepers made it possible for seafarers to navigate accurately and can be viewed at the Royal Observatory in Greenwich, London. The clock features the ‘grasshopper escapement’ operated by two inter-linked pendulums that compensated for the motion of a ship.  
This superb example features a cable-wound fusée which regulates the force exerted by the mainspring so that the power is constant from the beginning of the wind to the end.
Each clock is supplied with a copy of Dava Sobel’s book ‘Longitude’ which retells the amazing story of John Harrisons battle to create his amazing clock.

Due to unforseen circumstances, we now only have one remaining of this clock but without its wooden base and glass hood cover. Consequently, it is available at a reduced price from £9,600 down to just £2,500.
