I was mostly pointing out the sequence from Rolex > Seiko > Omega.

> Rolex invented the idea in the 50s

Your timeline is off: “In 1922, Rolex launched the Submarine – a watch attached on a hinge inside a second, outer case, whose bezel and crystal screwed down to make the outer case watertight.” https://www.rolex.com/about-rolex-watches/waterproofness.htm...

What they don’t say is the Blancpain Fifty Fathoms and Zodiac Sea Wolf both predate the iconic Rolex Submariner. By 1962 there where quite a few dive watches though rarely owned by people that used them for diving.

As to product placement that also goes back to the 1920’s films. By 1962 they where commonplace, though as you say hard to prove. Much like payola of the day, brands could make deals with individuals rather than the movie it’s self. Really it’s mostly the prominence in the early bond films that suggest otherwise.
