About MeThe invention in the 18th century of a timepiece capable of surviving the rigours of a sea voyage, and importantly remain accurate, was a major stride forward in ship navigation. By observing the stars position using a sextant and comparing that with the previously recorded position in readings taken at Greenwich at the same times (recorded in published tables) it was possible to accurately determine the longditude at sea.

This 8 day movement chronometer was made by James Hatton of London around 1822 and carries the number 272. Originally it would have kept in a gimbal to minimise shock whilst at sea and that inside a mahogany box. Such chronometeres were very expensive items at the time

It was owned by Captain William Edward who was master of Thermopylae when it sailed from Aberdeen for its delivery to Gravesend in 1868. The chronometer was mounted as a mantel clock when Edward retired from going to sea.
