First published in 1923, this long-awaited edition of the definitive reference work on the marine chronometer contains additional photographs and many of Rupert Gould's later revisions and corrections. It deals comprehensively with the chronometers history and the earliest attempts to measure longitude while including exhaustive discussions and diagrams of the various mechanisms employed with details of their inventors.

He was an early broadcaster on radio, giving weekly talks on the BBC's 'Children's Hour' throughout the 1930s; as a member of the 1940s discussion programme 'The Brains Trust' he amazed a national audience with his wide learning and photographic memory. Yet, his greatest achievements were horological: his restoration of the great Harrison timekeepers and his authorship of so many fine texts on the history of horology are his true legacy.
