Challenger Deep, which is nearly 7 miles (11 kilometers) deep. http://www.extremescience.com/DeepestOcean.htm http://news.nationalgeographic.com/news/2005/02/0203_050203_deepest.html http://en.wikipedia.org/wiki/Challenger_Deep I was watching on the history channel "How the Earth was made" and saw mention of this section of trench. Read up on it from the links above. rather cool. Now imagine if a human could dive that deep though they can't what it would be like. What life you may find there in those dark depths. Imagine a Diver watch built to withstand such a depth. nearly 36,000 feet or 11,000 meters. WOW!! :shock:

Skipdawg, Thanks for the links -- quite a coincidence, yesterday I read post by TLEX http://www.oceanic.blogspot.com at WUS re his appreciation of watches from an engineering / depth perspective v. the age old "what do you NEED 1000 meter diver for the shower" discussion. So on the way to work, I was trying to remember how deep the Marinara Trench is? I remembered the no. 7 ... 7,000 ' .... 7,000 meters ? 7,000 fathoms? I've done a lot of boating and offshore sailing, charts were in feet / fathoms... and we used "fathometer" to sound the depth. So I am curious, where in the watch world did things get mixed up with meters? I would love to see a watch that is rated in fathoms... do you know if any watches were dialed in this fathoms? Thanks for posting the links... quite amazing that fish, creatures, whales, porpoises, turtles regularly go to depths that would crush a human diver, and that it takes a hardened case of stainless steel or titanium for us to tell time where these creatures swim. Jim

I thought Rolex sent one to the bottom of the trench. Glad to know some of my brain cells are still operating.

About 10 years ago Roven Dino came out with the Mariana 9000 which was tested at the bottom of the trench (they lowered it in). The watch case was filled with a special liquid. Needless to say, the factory had to change the battery.

Any of Sinn's oil filled watches can do this. The trick is the noncomresability of fluids. If interior volume of the watch can't be compressed, then equal pressure is exerted outward regardless of the depth. Fish and squid work in the same principle. they generally have no collapsible cavities. since they are almost entirely fluid filled, the pressure of the watter has no effect on them. the only thing keeping them from the lowest depth is food, temperature and the ability to fed off predators.

Isthmus, That makes sense ... can't compress because squid and other creatures are liquid filled ...so there is no feeling pressure ? Jim

that is correct. Look at it this way. if you were to step out of your submersible i the marinas trench, the only part of you that would be crushed would be your gas filled spaces. That gas would probably be squeezed out of you and/or absorbed into your tissues, but once it is gone you would no longer feel the presure around you. Tha said, you also would not be able to breath. Do you remember that movie the abyss. In it there was a scene in which the main character tries on the seals liquid breathing aparatus. That idea (and I don't know if this is real technology, but I doubt it) works on the same principle.
