Technically speaking, the Aquatimer Deep Two is the ambassador of the new collection. Its predecessor, the GST Deep One, which featured a unique mechanical depth gauge with a split hand, had already demonstrated IWC's right to a place in the echelons of watchmaking technology. The Aquatimer Deep Two, with its further improved depth gauge mechanism, underlines this. As is the case with its predecessor, a wheel train is activated by water pressure and converts it into a movement on the depth gauge indicator. The latter displays current depth and maximum dive depth down to 50 metres. The Aquatimer Deep Two is water-resistant to 12 bar.The newly developed rotating outer bezel with its high-quality coating (which continues to glow for a long time under water) makes it very easy to read. The Aquatimer Deep Two continues to probe the depths of the oceans with the precision, unmatched performance and masculine understatement that is typical of IWC.
