The case design of the IWC Aquatimer Deep Three Replica Watch combines the advantages of the internal rotating bezel – such as protection of the scale against dirt and scratches – with the convenience of the external rotating bezel. The Aquatimer Deep Three is already the third generation of the IWC diver’s watches to feature a mechanical depth gauge. In both the Aquatimer Deep Two and the new Aquatimer Deep Three, the pressure-metering system is housed in a large second crown on the left-hand side of the case, protected by a bow. Water pressure acts directly on a membrane in the crown and pushes a pin towards the interior of the case. The continuous development of the depth gauge and rotating bezel system testifies to the Schaffhausen watch manufacturer’s resolve to further consolidate its technological advantage in complex mechanical solutions.
As practised divers are aware, scuba diving is a safe and exciting sport as long as you can rely on your equipment and observe a few basic rules: never dive alone; always ensure that you have a backup of your vital technical systems, such as regulators and depth gauges; and keep a close check on current depth, maximum depth attained during the dive, and dive time. This will allow you to ascend slowly enough and to make any necessary decompression stops. For the first rule, you have your dive buddy; for the second, your spare demand valve, or octopus; and for everything else, the new iwc aquatimer replica. Because if the electronics in your dive computer fail, the mechanical depth gauge and dive timer from Schaffhausen offers a reliable backup system for calculating all aspects of your dive.
This figure is vital for calculating any necessary decompression stops and, together with the other data, gives the experienced diver all the information he needs to complete the dive safely. The continuous improvement of the rotatingbezel system and depth gauge over three generations of the watch nicely illustrates what is probably Charles Darwin’s best-known quotation: “It is not the strongest of the species that survives, nor the most intelligent that survives. It is the one that is the most adaptable to change.” This movement operates the lever system that integrates the two indicators. During a dive, the blue depth indicator moves with increasing or decreasing depth across the white scale and always shows current depth. With the help of the seconds hand and the depth gauge, it is possible to keep ascent speed to a maximum of 10 metres per minute. The red indicator remains at the deepest point attained during the dive, to a maximum of 50 metres.
In addition, the scale under the glass, with its sensitive luminescent coating, was perfectly protected against water, dirt and scratching. At the same time, iwc replica watch was not as easy to wind the crown wearing diving gloves or under poor visibility conditions as it was to turn an external rotating bezel. It was for this reason that IWC’s 2009 Aquatimer collection came with an external dive time ring that could be rotated easily, even with gloves, and only anticlockwise, for safety reasons. In other words, if the ring was moved accidentally, it only showed a shorter residual dive time, which might have been irritating for the diver but was at least risk-free. The ring consisted of several parts and featured an inset four-millimetre-wide sapphire-glass ring, the lower surface of which was coated with luminescent Super- LumiNova®*. It has been made possible by an IWC invention: the sophisticated sliding clutch system transmits the rotations of the bezel to the interior of the case and the internal rotating bezel. Here, too – for safety reasons and thanks to the IWC SafeDive system – the internal rotating bezel, which engages in precise one-minute intervals, can only be moved anticlockwise.
