Water Resistant to 100 Meters - Real Life Implication ?

Well, the Deepsea Challenge was mounted on the OUTside of the submarine, on the robot arm; meaning there was no use for the HEV since the DSC was in water.

Correct --- the DS Challenge was attached on the outside and it took the ultimate water pressure that planet earth can create! So Kudos to it --- it is a triumph. And yes, in water submersion, a He escape valve is as useless as a piano is to an elephant....(infact a piano is pretty useless to most animals I can think of ).

I believe that any company, from Invicta all the way upto ROLEX and all in between (ok, not INVICTA ) --- well any company can create one or few pieces that can actually survive Challenger Deep, if they put their mind to it.......But to do it at a production level, that means, go into the store and buy one, even ROLEX has not been able to do so...yet!!!

Well when you think of back in the 1950s- 1960s with the first Bathyscaphe Trieste DSSD tests then in those old days,and now today with the modern day DSSD.In those old days no computers to design and simulate a test above or below water. So today with modern day materials in reality all they had to do is just build a box strong enough to take the pressure. IMHO the first Trieste test although the watch was huge by todays standards was far more of a achievement then than the modern day test.Although these type of depth ratings will never be used by man or superman, technically the DSSD is a fine watch.

Yes, but inside the submersible Cameron was wearing a DSSD instead of his trusty Submariner, and this is where the HEV could have come in handy.

AFAIK the submersible is not a mixed gas envirorment. It is pressurized but not with a He mix. The HEV wasnt required. Any watch could have made the trip down on his wrist.

Inside the pressure was just one atmosphere, normal surface pressure, and he was breathing the same air as on the surface which is around 79% nitrogen 21% oxygen so no need for HEV .

Rolex ratings are to be trusted, provided the watch is proof tested regularly before use.

I was using my old acrylic Datejust, rated only 50 m, for training / diving to 100 ft / 33 m. Never had an issue.

I think Team TRF has agreed that a Rolex 100m rated watch can be worn in vigorous water sports and wet environments with no worries.

Thanks everyone for taking the time to respond. I think the idea that Casio may have to limit due to buttons and electronics makes sense, too.
