If you want to dig deep, look at Dell Deaton's exhaustive research into the watches used in James Bond films. He's undeniably the world's leading expert on James Bond watches and has curated several exhibitions of Bond watch examples. Ian Fleming's family lent Dell Deaton Fleming's own Rolex Explorer ref. 1016 for one such exhibition, and he wore the watch (with the family's permission) while it was being transported. http://jamesbondwatches.com/
