steel and titanium, some featuring a chronograph complication, the IWC Aquatimer watches offer both great style and tremendous technical fascination. Consistent across this model range, is the unique rotating bezel, which is found underneath the crystal, and is operated via a crown on the side of the case. The most specialized models within the Aquatimer watch collection are the Aquatimer Automatic 2000 watch, which boasts exceptional water resistance for saturation diving, and the innovative Split-Minute Chronograph watch which employs a unique supplementary minute hand with a flyback function, thus enabling easier measurement of critical underwater times. The IWC Aquatimer watch collection is powered exclusively by selfwinding mechanical movements which have been designed for optimum durability and carefully adjusted for maximum precision by the watchmakers of the House.
