Perpetual Calendar

The design of the perpetual calendar was a feat of watchmaking genius that finally paved the way for IWC’s entry into the world of Haute Horlogerie. A mechanical masterpiece, it takes into account all the complexities of the leap years; in other words, it recognizes all the years that can be divided, without remainder, by four (e.g. 2012), as well as the centuries that can be divided, likewise without remainder, by 400 (e.g. 2400). These leap years all have a 29th day in February. Years at the turn of the century that leave a remainder when divided by 400 – the next ones are 2100, 2200 and 2300 – are not leap years. In cases like these, calendars with an analogue display will need to be advanced by one day on 1 March by a watchmaker. Calendars with a digital display can be adjusted by the owner. The perpetual calendar’s century slide with an analogue display turns each new century into a major event. The current century slide bears the numbers 20, 21 and 22 and will thus come to the end of its service life on 31 December 2299; but even now, IWC supplies the century slide bearing the figures 22, 23 and 24 for the years 2200 to 2499.


With their black, cockpit-style design and attractive mix of materials, the TOP GUN watches have carved out a name for themselves. The Top Gun logo on the reverse side is now engraved on the case back and is considerably more understated than the colour imprint. It is likewise impossible to imagine the Pilot’s Watch squadron without the military-look TOP GUN Miramar line, whose dial design was inspired by historic observer’s watches. Both watch lines are now supplied with an embossed black or green calfskin strap. In the case of the Big Pilot’s Watch Perpetual Calendar TOP GUN, the embossed calfskin strap is the only significant modification over last year’s model. The case diameter of the Big Pilot’s Watch TOP GUN models is now reduced by two millimetres and there have been slight modifications to the dial design. In the case of the Pilot’s Watch Chronograph TOP GUN and the Pilot’s Watch Chronograph TOP GUN Miramar, the ceramic case has been reduced to 44 millimetres. The designers have made the dial easier to read with the addition of a simplified date display. The analogue display of stop times between one minute and 12 hours is now found at “12 o’clock” in a totalizer that can be read like the time of day. Times under a minute are recorded by the central seconds stop hand. The new Pilot’s Watch Mark XVIII TOP GUN Miramar has a case measuring only 41 millimetres in diameter and is powered by the automatic 30110-calibre movement.

One of the most complex pilot’s watches ever built. The IWC-manufactured movement with its seven-day power reserve drives a whole range of watchmaking complications. These include a perpetual calendar with four-digit year display together with day, date and month displays as well as a moon phase indicator. All the displays are easily adjusted using the crown.
