Last year, IWC revamped its Ingenieur collection, introducing several new pilot’s watches. This year, it focused on diver’s watches, with eight new references in its Aquatimer collection. Of these, the Deep Three, comes equipped with a mechanical depth gauge that is water resistant to 100 meters. It is multi-functional, showing the current dive depth, the deepest dive of the session and, with the help of the seconds hand, it will also track ascent speed to a maximum of 10 meters per minute. The dive timer works by using an external ring that is indexed on an internal rotating bezel, which protects the scale against dirt and scratches. It works by means of a sophisticated sliding clutch system that transmits the rotations of the bezel to the interior of the case and the internal rotating bezel. The 46mm case is lightweight titanium. The caseback is engraved with a deep sea diver.
