Watching 'The Man With The Golden Gun' last night, which I've seen a million times so was paying attention to the background stuff instead and noticed Scaramanga's cool watch.
After a rather a long struggle with the internet I worked out it must be a Rolex 'King Midas'.
Then I found this image:
I quite fancy one but at £30K second hand not realistically going to happen.
Given that Christopher Lee was the inspiration for the character of James Bond, this must mean that Scaramanga is - technically - cooler than Bond, and so the Midas must be a cooler watch than the Submariner.
