The Clockmakers' Museum

The gallery will be closed to the public on 25–26 July.

Discover the world's oldest clock and watch collection in its new home at the Science Museum.

The collection includes more than 1000 watches, 80 clocks, 25 marine chronometers and a number of fine sundials and examples of hand engraving, which map the history of innovation in watch and clock making in London from 1600 to the present day.

Assembled by the Worshipful Company of Clockmakers and once located in the Guildhall, this remarkable array of timepieces traces the story of the capital's clockmakers from their first marine chronometers and mechanical clocks through the evolution of the wristwatch.

John Harrison was the inventor of the marine chronometer. Among the collection's highlights are the fifth one he made, which he completed in 1770, and a four-month duration longcase clock by the father of English watchmaking, Thomas Tompion.

Visit the Clockmakers' Museum and explore the fascinating history of timekeeping.
