Notes

The only other movement known by Robert Robin, fitted with the detent lever escapement, his own invention in 1791, and produced in his own lifetime, is a travelling clock in the collection of the Time Museum (Rockford, U.S.A.). A similar movement, No. 48, from the Courtney Ilbert collection, in the British Museum, is dated 1807 and was therefore made by his son eight years after the death of Robin. The inscription, on the back plate suggests that this movement Kwas produced soon after the invention of the escapement.
