The museums, the machines and the men and women who worked it out: laboratories kept as they were, beam engines under steam, the tunnel, the barrier, the roofs, and the plaques on the houses where the ideas came.
The oldest collection of clocks and watches in the world, six hundred watches and Harrison's H5 among them, in its own gallery on the Science Museum's second floor.

The Worshipful Company of Clockmakers began collecting in 1814 and moved its museum from Guildhall to the Science Museum in 2015, where it fills one long gallery with the history of London's greatest trade: Tompion, Graham and Mudge, the marine chronometers that followed Harrison, six hundred watches, eighty clocks, and H5, the timekeeper Harrison finished at seventy-seven and the King himself tested at Kew. It is free, like the museum around it, and quieter than anything downstairs.
