Jeg kan ikke nok om Rolex SD til at sige noget sikkert, men mon ikke oplysningen stammer fra en artikel i stil med denne, som jeg også indtil nu har troet på:
Et udsnit:
Doxa was not only the first with an orange dial dive watch and a rotating bezel with decompression times, but Doxa was also the first to bring a dive watch with helium escape valve on the consumer market. Especially the Rolex Sea-Dweller is well known for the helium escape valve and is often seen as the first dive watch with this feature. It was however Doxa who released the 300T Conquistador with helium escape valve in 1969. Rolex also made a dive watch with a helium escape valve but this was only sold to commercial dive companies like COMEX. It took Rolex untill 1971 (some say 1972) before they released a Sea-Dweller with helium escape valve for the consumer market
og hele linket: http://www.monochrome.nl/doxa-sub-first-...ape-valve/
Sjovt nok kan man også finde oplysninger som siger, at den automatiske helium ventil blev lavet i samarbejde mellem de to (og stadigt flere steder med at Doxa var først på det almindelige marked med den) - men sjovt hvis det i princip er samme begyndelse;:
Whilst many watch companies react to this effect by simply offering an even more robust case/crystal construction, Rolex and Doxa S.A. however thought of a different concept when they co-created the helium escape valve in the 1960s
Nogen med mere præcise oplysninger?
