The IWC Automatic Aquatimer Replica Watches

Mixed gas diving can take you even deeper though. You can reduce or even get rid of the nitrogen in the gas mixture you are breathing entirely, using other gasses like helium and hydrogen. Each of these, alone or in combination, can create their own problems, as can oxygen – we need oxygen to live, but what makes it essential for energy production in the body is its high chemical reactivity, which is also what makes it potentially dangerous. Deeper than about 60 meters, oxygen toxicity starts to become a problem too, and as you go deeper, you need to keep using less oxygen in your breathing mix. Because the Replica Watches nervous system is so metabolically active it’s especially vulnerable to oxygen toxicity and symptoms can include everything from visual disturbances to convulsions, which would be a sub-optimal event at depth.

However, if you take your time, know what you are doing, and breathe the right gas mixture, you can go shockingly deep. Compagnie Maritime d’Expertises divers reached 534 meters in experimental dives conducted in 1988. At that depth, pressure is 793.211 p.s.i. Now, intuitively it seems like you would simply be, to put it colloquially, squished to death. But IWC Replica Watches remember, as long as the total pressure of all the gasses in your body is equal to the pressure on the outside of your body, you’re good to go – to the extent that a third of a ton of weight per square inch, bearing down on you, in 534 meters of water, is good in any way at all. Your watch, by the way, is still fine and the atmospheric pressure inside the inner watch case is still equal to that at the surface.

This deep, however, physics and the laws of nature have decided that enough is enough, and they are trying to find IWC Fake Watches other ways to kill you. Enter High Pressure Nervous Syndrome. HPNS isn’t well understood even today – it might be due to toxic gas effects, or it could simply be high pressure causing alterations in nervous system functioning, or both. But it seems to be the factor currently limiting human deep diving. Symptoms include all sorts of unfortunate things like tremors, vomiting, and seizures – all things that are, as medical textbooks like to dryly put it, “incompatible with life.” HPNS is more or less completely incapacitating and since we don’t know how to beat it, diving deeper than the 500-600 meter range seems permanently out of reach.

As an illustration of just how powerful water pressure is at such depths, consider a somber event: the 1963 loss, with all hands, of the USS Thresher. The Cheap IWC Replica lead boat of what was to be a new class of ultra-advanced nuclear attack submarines, Thresher was lost when a reactor malfunction left her without power to maneuver. Without the ability to move forward, and trimmed to a slightly negative buoyancy, she began to sink deeper and deeper, eventually imploding as the water pressure outside the hull crushed her. The event was almost unbelievably violent – at the moment of implosion, according to a Navy study conducted in 1969, water entered Thresher at a speed of about 2,600 mph, and it was all over in a tenth of a second. The incident shows clearly that the problem is not so much pressure at depth per se, but rather, pressure difference. The Fake Watches depth at which Thresher’s pressure hull failed is thought to have been just past the current technical limit for human diving – somewhere around 700 meters.

Suppose, though, that it were possible to dive deeper – that HPNS could be defeated, somehow? Well, even the safest inert gasses, like helium, become narcotic if you go deep enough. The problem is that, at this point, we’ve run up against an absence of data. Human experiments in inert gas narcosis and deep diving have never been done at depths even half that of the depth rating of the IWC Replica Watches Aquatimer 2,000 Meters. Unknown (but probably lethal) gas intoxication effects aside, the other problem is that at such extreme depths, breathing gas mixtures eventually become too dense to breathe. One proposed solution: breathing oxygen rich liquid. Such liquids, however, would not be very efficient at removing waste carbon dioxide from the body – even at rest, you’d need to circulate about 5 liters per minute in and out of your lungs. This would be a lot more work than breathing air. So why own or wear a Replica Watches that can so dramatically exceed even the most extreme limits of the environment in which it’s designed to be used? I think the question reflects a misunderstanding in its asking. The fact that the watch so drastically over-performs is in fact the exact reason you would want it. It’s not necessarily a matter of bragging rights, or having a watch that acts as an enabler of idle Walter Mitty fantasies.
