Nice one thanks for sharing

Dannng YEAH!!!! I wanna buy one more SD now ..... these kind of rolex demos
get me going!! Yeah BABY!!! I fee like going to Walmart again and confronting that crook! Maybe we can tie him up to the rollie and send him down those depths.

ok, did the guy do any testing on the He Escape Valve? It would be nice to see that thing release a gas or two because most owners of SD will not be using that valve to release gas.
A digital sensor on valve would have been nice ....or detection of bubbles would show the valve in action ....

[SPACE-DWELLER]

Yes, I know that test. Very nice one!

Funnily enough, the Helium valve is rendered useless when OUTSIDE a submariner since the HEV is designed to release Helium particles that have entered the watch inside a diving bell. The divers inside the diving bell live in an artificial atmosphere with a high percentage of Helium, and during decompression, the Helium that entered the SD during the dive can make the crystal pop off it the SD did not have the HEV to release the gasses.

My next list will be SD. After Explorer 1 first.

You are right Bo ... there is no He in sea water ... it has to come from some pressurized environment where divers are working or probably anyone who goes down those depths in a submersible.... maybe the scientists studying the titanic ...so for the he valve to work, you gotta go through decompression from a highly compressed region like the inside of a sub to lets say the standard atmoshperic pressure...

For reference, this guy should have attached some watches rated for different depths, next to the dweller ... it would then be nice to see these watches imploding as the SD hold its ground ....

same info, in french ... I wish it was in english ...anybody knows how to convert?

thanks Sheldon for the english!

Great stuff, guys.....gives you some idea of how tough an SD really is.

Imagine a modern day nuclear Submarine being crushed from hull to hull if it goes below 2,000 feet.

And the SD is still smiling happily at TWICE that depth!!!

you're right JJ it is pretty darn amazing .. but on another topic, I saw a submersible that landed in the deepst point on earth, the Mariana's Trench, about 37,000ft deep ... and they saw little fish swimming around!! can you believe that? life that has adapted to such depths ....so next time you think you are under pressure, just think of th SEa DWELLER!

I hope it works.

Not too shabby but this baby went to 10915 meters, 35810 feet and is a two-tone model with an understated elegance I think the SD can't match.

I've seen photos of the submariners [not sea dweller] that were sent down with Piccard to the bottom of the Mariana's Trench. The crystal looked like a sphere cut in half attached to an oversize case... One of these watches went up for auction not long ago and was purchased by Rolex [I think they own 7 of the 8 made for this]

The pressure is: depth in feet X .445 psi (over 35,000 feet) around 7 tons/in2

The He passes through the crystal in saturation dives and loads the interior of the case, during the deco the crystal cannot off-gas fast enough, with excessive pressure pushing the crystal off, this happened to Comex divers and with the addition of the He escape valve to correct this problem the SD evolved from the Sub.

I've spent over 11,000 hours bottom time, I don't dive much anymore as I wish to keep my long bones. The Navy recently bought a friend of mine, Ron, an old sat diver, new hips. Ron is doing very well now.

Happy New Year, everyone
