As discussed in the Upcoming Seamaster Only book topic, we know the Omega Seamaster was used by Cousteau's divers team on their Conshelf 1 (August 1962), 2 (June 1963) and 3 (August 64) adventures.
Of course the "Oceanauts" had also been wearing Blancpain and Rolex Submariner watches.
Just wanted some input on these watches, screenshots from the Cousteau Conshelf adventure video:

 

Jacques Cousteau atop the DS2 saucer, the first submarine ever to make its base in a porthole domed diving bell on the sea floor...
.

 

you can pic a random brand as they wore everything that was available . on first two pics it looks like aquastar chrono

 

Looks like the Calypso crew always wore the latest in dive watch fashion...
For those enjoying wrist watch spotting in movies, L'odyssée is a must see ( Omega Seamaster... but new models as the film was made in 2016 )
