International Watch Co. Schaffhausen ?Fliegeruhr 5026, Perpetual Calendar? Pièce Unique.

One-of-a-kind BIG PILOT?S WATCH PERPETUAL CALENDAR The watchmakers at IWC Schaffhausen are truly ?engineers of fine watchmaking?, creating intelligent designs in a timelessly classical style. These creations have a lasting reputation for elegance and practicality. And here, the watch designers at IWC Schaffhausen have drawn on all the expertise at their disposal. The Big Pilot?s Watch, limited to one unique piece, brilliantly combines two outstanding mechanisms. Its driving force is the large IWC 5000-calibre automatic movement with Pellaton winding, a seven-day power reserve and date ? the same one found in the classic Big Pilot?s Watch. Mounted on this is a perpetual calendar of the kind familiar to IWC devotees from the Grande Complication and Da Vinci. The calendar functions are virtually identical with those of the models mentioned above, except that the mechanism has been enlarged. This makes the individual displays easier to read. Three subsidiary displays tell the wearer the date (at 3 o?clock), the month (at 6 o?clock), the day (at 9 o?clock) and the year (in four digits) in a window between 7 and 8 o?clock.
