Changing the clocks may be a chore but experts at the Science Museum in London responsible for some of the world’s rarest timepieces face a far more delicate task.
They will be turning back time on 35 of the collection’s 500-plus clocks as the nation moves from British Summer Time to Greenwich Mean Time tomorrow.
The Measuring Time gallery spans the centuries and is home to Britain’s second oldest surviving clock, the Wells Cathedral Clock, which dates back to 1392 and needs daily winding to operate.
Sunday’s clock adjustments will be overseen by the Science Museum’s conservator Richard Horton, seen at work above.
“It is quite a difficult job and requires specialist skills”, said Mr Horton: “It will be a very busy day.”
