Sea-Dweller and it's depth rating...

I'm going to throw out a couple questions. As I said in a previous post, I'm definitely not the physics maybe you folks can help me out with this. First of all, before I get to my MAIN question, just as a sidebar, if you have a watch, for example, the Sea-Dweller, which says it's good to 4,000 feet, does it literally mean 4,000 feet beneath the surface? Or is that 4,000 feet of pressure? Or is it the same thing?? I guess what I'm trying to ask is, lets say you're underwater 20 feet below the surface, and you're stationary. Then you start swimming. Once you start, does your motion, because of the resistance of the water, thereby exert MORE pressure on the watch, even though you're still at the same depth of 20 feet? You folks see what I'm getting at? Just kinda wondered exactly how that worked. As far as the main question thought...I was curious...why do we need the new Deep Sea to be rated at almost 13,000 feet? And I ask because, and maybe I'm wrong here, someone please correct me if necessary, but since no one will ever be going down that deep unless you're in a pressurized submersible, then technically, it wouldn't matter what the depth rating is, because the submersible is pressurized, isn't that true? That would mean that, in a pressurized submersible, at 10,000 feet below, a day date is as good as a GMT-Master is as good as a Deep Sea. Or is there something that I am seriously overlooking here?? I'm not here to do any bashing, you folks know that I do love my rolexes, and I appreciate the impressive statistics of the new Deep Sea...I'm just trying to figure out some physics here...any one have any thoughts on this????

Some interesting information posted on another forum regarding the DSSD,


As Roger mentioned it recently in a post, Rolex is still delivering watches to COMEX.
In fact the collaboration in between these 2 companies never stopped unlike what has been written
here and there.
The new Deep-Sea is certified 3 900 meters but in fact most of the tests took place at 4 500 meters
in collaboration with COMEX in a chamber specially designed by COMEX for the watch.
The watch has also been tested in water and not only the hyperbaric way. It is is said that the watch reached once 5000 meters.
This success is partly due to the ring lock system that is made with a mix of 904L steel boosted with azote, I dont know yet the name given
by Rolex for this new registered steell.
The watch is scheduled for august 2008 in your AD's and the price (I'm giving the official Swiss price
so anyone can translate in his own money) will be 9 700 CHF.
