In 2009, IWC from Schaffhausen launched the Aquatimer Deep Two with a mechanical depth gauge that offers maximum safety and security. This striking diver’s watch is a worthy successor of now discontinued GST Deep One Watch.
With a robust 46 mm case crafted from stainless steel, Aquatimer Deep Two watch is the largest member of the Aquatimer Family. The round case incorporates a mechanical depth gauge which insures water-resistance to sufficient 120 meters (400 feet).
Further-developed Depth Gauge Mechanism
The watch contains a complete backup system that permits the diver to measure and plan vital parameters, such as dive depth and time in the event of a dive computer failure. It shows not only the actual dive depth, but also the maximum depth reached during previous dives. Compared with its predecessor, the GST Deep One from 1999 which was capable of measuring depths down to 45 meters, the new watch is able to measure water depths down to 50 meters.
Its pressure measurement system is built around a special membrane located in a second large crown on the left side of the case. The water pressure acts directly on a membrane inside this crown and forces a pin into the interior of the case, activating a lever mechanism directly connected to the watch’s hands. The deeper the timepiece is plunged, the stronger membrane is forced inside the case, activating both red and blue levers. The red indicator moves to show the maximum depth reached by a diver, whereas the blue one displays the actual dive depth.
The red lever always remains at the greatest depth reached and it can be reset to zero by pressing the smaller button, which is situated underneath the depth-gauge sensor crown on the left side of the case.
The Maximum Safety in the Depths
The enormous case incorporates the external rotating bezel with a tachymeter scale inscribed with Arabic numerals to mark dive time in five minutes steps. The first quarter-hour on its black PVD coated bezel is colored in dark blue, which is one of the hallmarks of the Aquatimer Family.
At the heart of the Aquatimer Deep Two beats the high precision Caliber 30110 automatic mechanical movement (based on the famous ETA 2892-A2). The IWC-manufactured self-winding movement is built on 21 jewels and provides 42 hours of power reserve when fully wound. The same movement is incorporated in the Aquatimer Automatic 2000.
The sleek and uncultured black dial features luminescent hands and hour markers. The hour and minute hands are framed with a striking red, while a thin second hand has the red colored tip. The Swiss manufacturer coated the case of this diver’s timepiece by convex sapphire crystals with antireflective coatings on both sides. Further, the case back is encrusted with an elaborate relief engraving of a diving helmet.
IWC from Schaffhausen offers two versions of the Aquatimer Deep Two. The first model IW354702 is attached to a black rubber strap with a pin buckle, while the second version IW354703 is accessorized with a stainless-steel bracelet with a double push-button safety clasp. The wristlet features a quick-change system, developed by IWC under the patent license from Cartier, which allows the wristlet change in a few seconds without the need for any special tools.
For the past two years, IWC Aquatimer Deep Two Watch became a symbol of ruggedness combined with suitability for everyday wear. This striking and highly functional diving-instrument comes with the price tag of approximately $16,000.
