The Big Pilot’s Watch Perpetual Calendar TOP GUN, the Big Pilot’s Watch TOP GUN and the Pilot’s Watch Chronograph TOP GUN combine the black-and-white instrument look of the classic Pilot’s Watches with the sporty design of the TOP GUN line. The cases made of black zirconium oxide together with the crown and push-buttons in titanium underscore IWC Schaffhausen’s pioneering role as one of the first companies in the watchmaking industry to use these materials. In the Big Pilot’s Watch Perpetual Calendar TOP GUN, the IWC-manufactured 51614 calibre with a 7-day power reserve drives a plethora of watchmaking complications. The perpetual calendar with displays for the date, day, month, year in four digits and perpetual moon phase takes into account all the leap years in the Gregorian calendar until 2100. The in-house 51111 calibre found in the Big Pilot’s Watch TOP GUN likewise builds up a power reserve of 7 days after just 1960 complete revolutions of the rotor or after being fully hand-wound. No Pilot’s Watch collection would be complete without a chronograph with down-to-the-second precision. Among the TOP GUN models in traditional cockpit design, this role falls to the Pilot’s Watch Chronograph TOP GUN. As only fitting, it comes equipped with an IWC-manufactured movement in the form of the further improved 89365-chronograph calibre. A soft-iron inner cage protects the precision movement against magnetism.

Perpetual Calendar

Analogue date displays with hands have a long tradition in IWC watches featuring perpetual calendars. In the case of the Portugieser Perpetual Calendar, for instance, the date, day and month are to be found on three subdials and, thanks to the clear layout, are extremely easy to read.

The classic moon phase display with discs is usually found at “12 o’clock”. The Ingenieur Constant-Force Tourbillon is one exception and displays the double moon at approximately “1 o’clock”. The moon phase display used in the Portugieser Grande Complication is astonishingly accurate and deviates by just 0.002 per cent, or 1 day, in 122 years. The Portugieser Perpetual Calendar is even more precise. Larger moon phase wheels with a higher number of teeth reduce the deviation so drastically that a future inheritor of the watch would theoretically need to take it to a watchmaker to have the moon phase display adjusted by only 1 day in 577.5 years.
