A Victory watch commissioned for Winston Churchill is to cross the block at Sotheby's London.
The lot is valued at ?�60,000-100,000 ($92,679-154,465) ahead of the September 22 sale.
It's inscribed "1939-Prime Minister Winston Spencer Churchill-1945" and displays an enamel dial showing St George slaying the dragon.
The well known French maker Louis Cottier, in collaboration with Agassiz and Co, was responsible for the design of the piece.
Sotheby's explains: "Commissioned by a group of prominent Swiss citizens in acknowledgement of Churchill's strength and leadership during WWII, the watch was much treasured by Churchill.
"On receiving the watch in 1946, he wrote to thank the group for their 'superb gift', saying it would always remind him of their 'beautiful country' and 'friendly feelings'.
"He added: 'I admire so much the care and the quality with which this delicate example of craftsmanship and Swiss precision was realised.'"
Four watches were produced. The other three were presented to Charles de Gaulle, Joseph Stalin and Harry Truman.
