Now in todays vintage Rolex market and suppose today its one of the most sort after Double Reds and now as rare as hens teeth .Seen one sell for a while back for well telephone number prices $158000 US,and to the correct Rolex watch collector just ask your price now could be up to $200000 US.Now it was around 1969 when Doxa introduced the first divers watch equipped with a Helium Release Valve, that was available first to the general public.And its widely believed to have been co-developed by Doxa and Rolex at that time.Now Rolex submitted a prototype patent on 6th November 1967, its thought only around 50 of these double Red 1665s were distributed with patent pending stamped case backs.Although Rolex fitted Submariners (model 5513 - non date) with prototypes of this escape valve, for the COMEX divers.They did not start to build the Helium Release Valve into their retail dive watches until the SD in 1971,two years after the Doxa.Now after a bit of negotiations with Doxa and both companies had a very good working relationship.So its widely believed they decided to share the Helium/Valve patent,just to get it into production and for sale to the public the new HEV Rolex Seadweller.
