Timekeeping

Navigators knew that if they could accurately measure time that it would be significantly easier for them to find their longitude at sea, however, the technology to do this was not perfected until the 18th century. This section looks at the progression of tools used to measure time: the sand glass, sundials, various pre-Harrison marine chronometers, and, finally, the invention that won The Longitude Prize: The Harrison Clock.
