S.T. Dupont 5174 Cufflinks
James Bond (Daniel Craig) wears a pair of S.T. Dupont 5174 cufflinks in Casino Royale during the first meeting with Vesper (Eva Green) in the highspeed train to Montenegro.
The 5174 cufflinks are square with a curved lines design, made from palladium (also available in gold and in black).
Note that the new versions of the 5174 and 5172 both have slightly different closing clasps compared to the 2006 version seen in the film. The design of the actual cufflinks (the top part) is still the same.
These cufflinks are still available in jewellery stores. Or contact Bond Lifestyle if you're interested in buying S.T. Dupont Cufflinks.
In the same movie, Bond wears S.T. Dupont 5244 cufflinks during the Casino scenes (with his tuxedo), and S.T. Dupont 5172 cufflinks when Bond gets in the taxi after the train ride and later when he checks out the gear in the glove compartment of his brand new Aston Martin DBS.
