Yep, in the novels Bond wore what is most likely to be an Exlporer, Fleming chose to give bond a Rolex, where as Omega chose to give Bond an Omega.
Its all advertising that is prevalent through all bond films, especially the newer ones. BMW, OMEGA, Persol glasses, Samsonite, Gucci, and SONY phones
Daniel Craig in reality wears several Rolexs. Its also rumored he has a 6358 Submariner, like the one Sean Connery wore in the old Bond flicks
