The watch was bought for 790 Swiss francs in 1968, and will be auctioned together with the original invoice and a handwritten note from Bucherer, which says “this is the watch for James Bond”.
The heavy silver watch, with a unique chronograph hand, was designed by Swiss jewellers Bucherer.
Writing in his 1953 novel, Casino Royale, Fleming specified that 007 “could not just wear a watch.
Though Bond has sported an Omega in recent outings, in his original books, Fleming was very particular about the watch his spy should wear.
