Summary
| Description |
John Harrison's marine timekeepers H1, H2, H3 and H4 are the most important ever made. We saw them on display at the Royal Observatory Greenwich, in the Time galleries. The clocks are extraordinarily beautiful objects of themselves, as well as being revolutionary in their ability to allow ships to determine their longitude at sea. This development drastically reduced the risk of ships and their crews, along with their precious cargoes, being lost at sea. Read more at www.rmg.co.uk/see-do/we-recommend/attractions/john-harris...
