SD owners your watch can do this

[Degas]

Although my SD4K is about to dive only to a max depth of about 60M, it is good to know that:

"The design and actual availability of diver's watches certified for more than 1,000 m (3,281 ft) is not solely explicable by practical diving needs.

The diving depth record for actual off shore diving was achieved in 1988 by a team of professional divers of the Comex S.A. industrial deep-sea diving company performing pipe line connection exercises at a depth of 534 metres (1,752 ft) of seawater (msw) in the Mediterranean Sea. The diver's watches used were Rolex Sea-Dwellers.

In 1992 Comex diver Theo Mavrostomos achieved a record of 701 metres (2,300 ft) of seawater (msw) in an on shore hyperbaric chamber. He took 43 days to complete the dive. The watch used during this scientific record dive, where a hydrogen-helium-oxygen (hydreliox) gas mixture was used as breathing gas, was a Rolex Sea-Dweller 16600 with a 1,220 m (4,000 ft) depth rating. Rolex used this achievement in advertising campaigns.[9][10][11][12][13]

Fun facts. The SD is such a solid reference!

If you are about to go to 60m that is still pretty impressive. I once stood in a swimming pool with my Submariner, the poor thing! It will NEVER reach the depths it was intended to while on my wrist

I believe the open circuit scuba depth record is around 1000 fsw. IIRC, the rapid descent caused HPNS tremors and he had trouble keeping his reg in his mouth. I don't know whether he was wearing a watch or not, but a Sub would probably have survived the dive.

My Explorer has been to 65 m with no troubles. I doubt I'll be taking my SD to 65% of its' crush depth

I'm blind!! just saw THIS DSSD in the same link

Speaking as someone who is careful about how deep his bath water is, can someone answer a couple of questions for me please?

1 Any idea about how much a deep-sea diver is paid by the likes of Comex?

and

2 In the description above about the 701 m 'dive', does the fact that it was done in an on shore hyperbaric chamber actually mean that the 'dive' was not in water but in a pressure changer on land? If so, are these 'dives' done just to test humans and equipment or is there another reason for doing this? 43 days locked in a steel box, wow!

[whysleep]

It might get your watch scratched, don't dive with it!!

[RolexAuthority]

The DeepSea will do an astonishing 3.9km!!!! Wow

[leicashot]

My old SD went pretty deep as you can see, and never skipped a beat!

Commercial divers are paid pretty well. There's at least one TRF member who is a current diver, perhaps he'll weigh in.

A chamber dive is a test dive under very controlled conditions. The 'diver' is stressed at the same pressures as would be achieved in water, without all the logistics of a wet dive. However, chamber dives do not correlate exactly to in water dives. They do provide excellent data for saturation diving physiology that can be used to prepare for wet dives.

The descent rates (blow down rates), decompression rates, and other safety and physiological parameters were determined largely in the chamber, then tested in water.

That is really cool!
Thanks for posting.

[watchwatcher]

Hmm...guess I need one now.

[ratty]

So does anyone know how much more pressure the diver and watch are under at 700m compared to at sea level?

[dysondiver]

yep , every 10m is one bar ,,,, and add one for surface pressure ,,,
all these deep dives are very good , but did anyone look for condensation or water damage to their watch at the end ,,,
i can think of one thread here that would not agree with some of the above.

[dysondiver]

oops , forgot the answer , 72 x15.6 = 1123 psi , thats 11x the pressure in a truck tyre.

[ratty]

1123 psi wow!

I had no idea that the human body could survive such pressures!

Do you know what the max pressure is the body can stand?

[dysondiver]

the bods quite an amazing bit of kit , as the divers here will tell you , its the airspaces that make things tricky , inner ear , lungs sinus etc , as long as they are equalized the body can stand a lot of abuse , we are mostly water after all , and water is only compressed by , one half of one percent [ by volume] per thousand psi ,,, but it only takes a one psi differential between inner and outer ear to burst an ear drum... an average dive say 30m has the divers bod at 4 bar , thats aprox 60 psi , or twice whats in your car tyre.

[dysondiver]

heres anther interesting thought ,,,, the record for longest breath hold , last time i checked was




























over 20 mins.... now thats amazing

[ratty]

I take it we are still talking about humans and not whales?

yep ,,, saw the guy doing the record on tv ,,, they do it in a pool to get the best of the human dive response , ie being dunked in water slows down just about everything heart metabolism and the likes , it was quite an amazing feat to see , its probably on u tube

[tkerrmd]

great watch, no doubt!

[Wcdhtwn]

I've been trying to talk myself out of one... you're not helping.
