IWC Schaffhausen Pilot’s Watch Double Chronograph Edition TOP GUN Ref. IW3799

The IWC Pilot’s Watch Double Chronograph Edition TOP GUN bears the name of the US Navy Fighter Weapons School, the elite academy that trains the very best fighter pilots in the world.

tWith a case made of hightech ceramic. The operating elements and the back are in matt grey titanium. Its mechanical internal workings are of the finest quality. And it is TOP GUN. That is to say, just as above-average skills are demanded of the graduates of the United States Navy Fighter Weapons School, so IWC has drawn its inspiration from this elite academy for pilots and in the TOP GUN has created a pilot’s watch for the highest echelon of professionalism.

The Pilot’s Watch Double Chronograph Edition TOP GUN takes its place in the Classic line from IWC, which concentrates optically on the reduced simplicity of the on-board aircraft instrumentation. The aeronautical know-how of IWC goes back more than 70 years, to a time when ambitious aviation was in its infancy.

The Pilot’s Watch Double Chronograph Edition TOP GUN features a high-tech ceramic case combined with titanium. The watch bears the TOP GUN logo not only discreetly on the case flank, but also boldly on the back of the watch. For this mechanical watch with its distinctive technical functions and its uncompromising cockpit design – even down to the date indicator resembling an altimeter.
The Double Chronograph in its 46 mm case is worn on a robust nylon strap. Standing out against the contrasting black and white of the dial and the hands are the small seconds hand and the rear counterweights of the two central seconds stop hands in signal red. The latter are in the form of fighter aircraft, as an additional small clue to the genealogy of this exceptional watch.

The two seconds stop hands, which lie one on top of the other in the rest position, nevertheless primarily draw attention to the particular horological speciality of the Double Chronograph with its rattrapante or split-seconds function: this permits the measurement accurately to the second not only of stop times, but also of any desired intermediate times within a given minute. This exquisite function, perfected by the engineers at IWC some years ago, is operated by the third chronograph button at “10 o’clock”.

It is used to stop the so-called fly-back hand separately, in order to record an intermediate time, while the central chronograph hand continues to run. A further actuation of the button brings the fly-back hand instantaneously into synchronization with the stop hand, whether it is at a standstill or in operation. The aggregate time recording by the totalizers on the black dial extends up to 12 hours.

TOP GUN, in relation to a pilot’s watch of this class, naturally also implies maximum protection of the movement against magnetic fields by an inner case made of soft iron. This special feature has characterized IWC pilot’s watches since the Mark 11 (1948), which saw service in the cockpit with the Royal Air Force, amongst others. As a matter of course, the sapphire glass of hardness grade 9 is coated on both sides and secured against displacement by a sudden drop in air pressure.
