The diver’s watch with a mechanical depth gauge makes a return after ten years in the form of the Aquatimer Deep Two, pressure-resistant to 12 bar.
Like its predecessor, the IWC GST Deep One from 1999, it shows not only the actual dive depth, but also the maximum depth reached during a particular dive. It thus doubles as a complete second safety system alongside the dive computer.
Whereas the GST Deep One was able to measure water depths down to 45 metres, the Aquatimer Deep Two features a semi-circular indicator on the dial, which records depths down to 50 metres. Its pressure measurement system is contained 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. This movement actuates a lever mechanism connected to the measurement hands.
However, only the raised tips of the hands at the level of the dial can be seen to move over the indicator scale through a semi-circular slot in the dial. The hands in this case are led around the movement. This is an ingenious solution, which avoids the need for the path of the arbors to pass through the movement.
The depth indicator (blue)moves over the white measuring field as the depth of water increases or decreases. The maximum depth indicator (red) always re mains at the greatest depth reached. It can be re leased by a button underneath the depth-gauge sensor crown on the left side of the case.
The new IWC Aquatimer Deep Two watch is the only member of the new Aquatimer family with a case diameter of 46 mm. It houses a 30110-calibre automatic movement with central seconds, date display and 42-hour power reserve. This stainless steel watch comes with an elaborate relief engraving of a diving helmet on its case-back.
IWC Aquatimer Deep Two is available with a black rubber strap or stainless steel bracelet.
