IWC Schaffhausen Big Pilot’s Watch Perpetual Calendar Boutique Edition (Ref. IW502639)

The red gold Big Pilot’s Watch Perpetual Calendar Boutique Edition comes with a perpetual calendar and the original 46.2-millimetre case diameter of the Big Pilot’s Watch launched exactly 10 years ago. An impressive time machine with a gold-plated dial featuring the time as well as displays for the date, day, month, year in four digits and double moon for the northern and southern hemispheres.

The 51614-calibre automatic movement has a 7-day power reserve. The time remaining is displayed on the watch dial. Equally unique and typical of IWC is the independent, mechanically programmed calendar with its complete, fourdigit year display, which will require no correction until the year 2100 and can be advanced, together with all the other calendar displays, in one-day steps via the crown. The Big Pilot’s Watch Perpetual Calendar Boutique Edition, the biggest of the three models in this special edition, also comes with a sapphire-glass back. It is limited to 250 pieces.
