Whats the deepest rating watch on the market?
The Rolex Sea Dweller Deep Sea is supposedly the dive watch with deepest rating of any mechanical watch, my question is this; What IS the deepest rating of any dive watch produced today (pics please)...I found this one...(11,100M!!)

Well in the majority of cases the depth ratings is irrelevant on most high rated watches as it will never be used by man or future man.But it still quite a skill and a technical achievement on the part of the case designer, and suppose they make them because they can.But today IMHO its little more than a brag factor mine is bigger than yours etc.

The Hydromax is liquid-filled, and thus has no practical limit on its depth rating. The 11,100 meter rating is based on the depth of the deepest part of the ocean, the Marianas trench. Since the liquid 'pushes out' with as much force as the ocean pushes in, it could go to greater depths if they existed. The limit would be the molecular failure point of the materials used in its construction, around 30,000,000 psi, the point at which hydrogen turns into a solid metal.
Not incidentally, the depth rating of a watch is an academic exercise only beyond about 1000 meters of water, since no human could or ever will work unprotected at depths much beyond about half that value. |

Well, I could be wrong, but I believe the CX Swiss Military Watch is actually the deepest for any mechanical watch - at an also insane 20,000 feet. This too is a relative bargain at about $4,000 when compared with our $9,800 16,000 feet DSSD. This said, though, and IMHO, and having played with all of them in my grubby little hands, the DSSD came out on top overall for me. In terms of appearance, style, uber engineering, pedigree, the rich DEEPSEA history, lineage and mystique surrounding its development over 50 years ago, it was hard to pass up. At the end, the DSSD was truly the only choice for me. Sure others agree similarly. BEST REGARDS |

There are many dive watches in the 3000 + meter range
You also have a few watches that are really out there like the PITA Oceana that is rated to 5,000 meters / 16,404 feet and the above mentioned CX Swiss Military 20,000 feet or 6,096 feet Then there is the Deep Sea Special from Rolex at 10,908 meters / 35,797 feet Then you have the three silicone oil filled watches (That I know of, there may be more)
Remember this, in 2009, the ROV Nereus went to a depth of 10,902M / 35,767feet in the Challenger Deep (http://geology.com/press-release/dee...-of-the-ocean/). A depth that hasn't been seen since the Bathyscape Trieste's dive in 1960, and that was a manned submersible. 35,767 feet roughly equals 6.8 miles exerting 8 tons per square inch (thats the equivilent to 48 Boeing 747's on a square inch) Oh yea, I almost forgot, add 25% to the depth of mechanical watches per ISO 6425 for still water test.

Actually the deepest open-circuit dive on SCUBA was in 2005 to 330 meters / 1,082 feet by Pascal Bernabe off Corisca, and the deepest working dive was acheived by Comex in 1988 to a working depth of 534 meters / 1,753 feet in the Mediteranean. Regarding hyperbaric tests, Theo Mavrostomos acheived 701 meters / 2,300 feet dry in 1992.

Force exerted, not weight.

The PITA is one of the coolest out there for sure!
I really want one! For some reason I am drawn to the Rose Gold and PVD version but I think I should just go with a stainless.

Ouch. I wonder though if we've ever planted this on the ocean floor as we did on the moon. O f course we can't see it...

All I know is that these watches can go a lot deeper than I ever will! One thing that has always puzzled me is they say the 30M and 50M watches should really only be worn in the shower. For actual swimming, you should have a 100M watch as a minimum. Sounds like the ratings are not quite accurate with the anticipated exposure...

i dont what really is going on here- as someone stated - the Bell & Ross Hydromax is 11000 meters thats over 30000 feet. AND IT IS! So why are people chipping in with 20000 feet. Basic Math(S) solves that. Also I have the watch time magazine to prove it too;) With teh one at 20000 feet in second place

Not that it matters.
Once you start equalising the pressure by filling the watches with liquids, the actual depth printed on the dial becomes largely arbitrary. |

Very true, it really is arbitrary since the quartz movements stop functioning at 16,000 feet.
