The IWC Replica Automatic Aquatimer 2,000 Meters

The IWC Automatic Aquatimer 2,000 Meters is a watch designed to withstand the pressure found at a depth of two kilometers. It looks and feels every inch the part, but could anyone ever – even theoretically – wear it that far down and not instantly implode? Let’s look at the watch itself, and at the same time conduct a little thought experiment on what might happen if you tried to go as deep as the watch can.

This particular version of the Aquatimer has the greatest depth rating of any model in the current Aquatimer collection, but it’s not the first 2,000 meter rated Cheap IWC Replica. The very first was the IWC Ocean 2,000, which was a collaboration with Porsche Design made back in 1982. Despite the extreme depth rating, the watch – also the first wristwatch with a titanium case and bracelet – was not especially big, at 42mm x 12.6mm; not a dress watch by any means, but still not terribly beefy by modern standards. The IWC Replica, on the other hand, wants you to have no doubts as to its toughness. It’s 46mm x 20.5mm, although the SafeDive bezel system probably involves some extra girth and thickness as well. The SafeDive system consists of an outer bezel, which rotates an inner bezel via an internal gear linkage; the idea is to combine the ease of use of an outer bezel with the legibility of an inner bezel. A dive watch with a SafeDive system is actually rather similar in construction to a modern submarine – subs, in general, have an outer hull which provides good hydrodynamics and streamlining, and an inner pressure hull which contains the living and work spaces for the crew. Likewise, the IWC Replica Watches SafeDive system involves an outer case which allows the ingress and egress of water, and an inner case, which is responsible for protecting the movement. The protrusion at 9:00 houses the coupling gear mechanism linking the inner and outer bezels.

Now, let’s talk about depth. Every meter of water exerts an additional amount of pressure above what air pressure is at sea level; the exact amount is an extra 1.422 pounds per square inch per meter. The deeper you go, the harder the water pushes on you. The Professional Association of Diving Instructors recommends 30 meters as a limit for recreational scuba diving, at which Replica Watches UK point pressure is 42.67 p.s.i. If you are breathing normal compressed air, which is largely oxygen and nitrogen, your body will absorb additional nitrogen as the nitrogen already in your body is compressed. At the surface, you have about 1.5 liters of nitrogen dissolved in your blood and body fluids; at 10 meters, however (one atmosphere’s worth of pressure) this doubles to three liters.

There are two main problems with having more nitrogen than normal dissolved in your body. The first is that if you ascend too quickly, the extra gas will form bubbles in your body fluids as it comes out of solution. The result is decompression sickness: headache, severe joint pain, and even paralysis are some of the symptoms. The Cheap IWC Replica other problem is that nitrogen is a narcotic, and if you have too much of it in your body it will basically make you drunk. This phenomenon is called nitrogen narcosis, and it can cloud a diver’s judgement badly enough to make you think you’re swimming up when you’re swimming down, which is clearly a potentially fatal circumstance. It’s not a coincidence that the PADI limit is 30 meters, by the way: that’s the depth at which nitrogen narcosis symptoms start to become noticeable in most adults. However, you can get around all of this by breathing a gas mixture that reduces, or even eliminates, nitrogen.
