Power Reserve, Rotating Bezel, Luminescent Hand
This chronograph in 18 ct. red gold (5N) is IWC's first diver's watch with a precious metal case and a transparent sapphire glass case back. Make no mistake: this is a thoroughbred luxury timepiece, both under water and on dry land. Equipped with the same highly developed case technology as the other models in the Aquatimer family, its functional design is combined here with the advantages of the IWC manufactured 89360 calibre movement. The circular IWC automatic movement with its 68-hour power reserve and double-pawl winding system features a largely off-centre chronograph mechanism controlled by a column wheel: all in all, a design that meets the highest possible standards.The wealth of sophisticated technical features inside the chronograph is no less impressive than the case itself, which is an imposing 44 mm in diameter and has been tested for water resistance to 12 bar. Times recorded by the stopwatch are as easy to read on the dial as the time of day. And, thanks to the flyback function, the chronograph is ready to start timing again in the twinkling of an eye.Mechanical chronograph movement, flyback function, self-winding, 68-hour power reserve when fully wound, small hacking seconds, date display, screw-in crown, mechanical rotating external bezel, luminescent elements on hands, dial and external bezel, sapphire glass with anti-reflective coating on both sides, transparent sapphire glass back, bracelet quick-change system*, water-resistant to 12 bar, case height 15.5 mm, diameter 44 mm.
