I highly commend
@Mspeedster for discovering new facts about James Bond's watches, as well as technological advances.
The members of this forum are all great.
And I would like to supplement the fact that Bond's watch is Heuer.
In another scene in this movie, the adversary uses a watch to signal to the outside, which is an Airline with Heuer logo.
Taken together, it is very likely that the Bond watch was Heuer logo, and I think we was able to get confirmation from the photos

This discussion has been repeated for many years, but I believe it has come to an end here.
