Although we can already see James Bond sporting a nice wristwatch in the earlier bond films, no secret devices were integrated into the watch by Q. The first film in which the watch becomes more than a mere watch was in the movie Thunderball, the fourth James Bond movie which was released in 1965. James Bond has worn countless well-known watch brands such as Rolex, Breitling, Seiko, and of course Omega.
James Bond's partnership with Omega started in the movie, Goldeneye in 1995, which stars Pierce Brosnan. Omega's Seamaster Professional with Q's add-ons helps James Bond escape countless deadends. It is Omega's Seamaster Professional again that helped James Bond in his next outing Tomorrow Never Dies in 1997, again in the movie The World is Not Enough in 1999 and repeated again in Die Another Day in 2002. In all four movies of Pierce Brosnan as James Bond from 1995 to 2002, James Bond all wore Omega watches fitted with Q's wizardry from remote detonators, laser beams, incorporating a grappling hook into the watch, helping James beat all odds that are up against him.
When Daniel Craig took over as James Bond in 2006 with Casino Royale, we see James Bond wearing not just one, but two Omega watches: a Seamaster Professional and Seamaster Planet Ocean.
In Spectre, he reveals in his left wrist, the Omega's Seamaster 300. When all seems lost from being tortured horribly by Ernst Stavro Blofeld (Christoph Waltz) who is drilling tiny holes in his face, James turn to his ever reliable Omega Seamaster Professional for help and was again able to escape certain death.
