The dramatic story of John Harrison's 18th century solution to the problem of longitude. He invented a mechanical device that kept accurate time at sea - the chronometer - and Sobel's story of his 40 year quest to build the perfect timekeeper provides not just an account of the absorbing social background to the tale, but also a fascinating history of astronomy, navigation and clockmaking.
