Our collection focuses on three key areas: precision marine timekeeping for navigators, precision timekeeping for astronomers and the broader area of domestic timekeeping and time distribution.

Between April 2014 and January 2015, Royal Observatory Greenwich was taken over by steampunk artists inspired by the 18th-century race for longitude.
