The Lazenby Watches
James Bond - George Lazenby Models
On Her Majesty’s Secret Service
Lazenby has the distinction of being the first Bond to wear a Submariner on an Oyster bracelet. He wore a Rolex Submariner 5513, but during the scene where he has to break into an office to open a safe and copy some documents, he takes a Rolex Submariner 6358 off his wrist and puts it on the machine with the crown unscrewed. Later in the film he is sporting a Reference 6238 Chronograph also on stainless steel bracelet.
"Bond surveyed his weapons. They were only his hands and his feet, his Gillette razor and his wrist-watch, a heavy Rolex Oyster Perpetual on an expanding metal bracelet. Used properly, these could be turned into most effective knuckle busters." –Ian Fleming [On Her Majesty's Secret Service].
