All mechanical watches can be fascinating because of their intricate movements. Even simple watches, ones that only tell time, are extraordinarily complex mechanisms that have hundreds of miniscule parts that work harmoniously together. A complicated watch, one that performs additional functions, is by definition even more complicated.
A fabulous combination of sportiness and elegance, the Spitfire Perpetual Calendar Digital Date-Month is the high-flyer of the IWC Pilot's Watch collection. The date and month could not be easier to read and the mechanics inside the case are an endless source of fascination.

It’s no accident that this calibre has a gold medal
—Kurt Klaus, the legendary watchmaker who further improved this movement
Also rightly called the big IWC calibre. Manufactured in-house at the factory in Schaffhausen, it resulted from the first movement in the 5000-calibre family for a limited series of Portuguese watches in 2000. It also marked the revival of the Pellaton pawl-winding system at IWC. The version of the 51011 illustrated here, featuring circular graining, nickel plating and Geneva stripes decoration, is the driving force behind the Portuguese Automatic with small seconds, date and power reserve display.
