Most luxurious watches have a history behind them. The IWC Big Pilots Power Reserve watch is no exception. Before IWC produced the first Pilot’s watch in the 1930’s, pilots had used large pocket watches to tell the time. These timepieces were difficult to operate and access, so the Pilot’s wristwatch was a success with pilots. It was the largest watch in the world – its case measured 55mm in diameter and 16.5mm in height.
The modern day IWC Big Pilots Power Reserve is less large – it has a 46.2mm case with a 15mm height. The timepiece comes in two versions – either in white gold or stainless steel. The watch has the same black dial as in the original Pilot’s watch, but a few improvements were made: there is now an indicator of power reserve positioned at three o’clock and a date display window at six o’clock. The iron inner case of the watch provides a shield protecting it from magnetic fields.

The IWC Big Pilots Power Reserve watch is powered by Calibre 51111, an in-house self-winding movement. The most outstanding feature of this automatic movement is that it provides a seven day power reserve which is unusual in self-winding watches.
The maximum depth at which water will not penetrate the case and damage the movement is 60 meters, which means that it can be safely worn while swimming but is not suitable for diving.
The movement is equipped with the Pellaton winding mechanism, invented in the mid-twentieth century and named after its inventor Albert Pellaton, technical director of the company at that time. Thanks to this mechanism, the durability of the rotor wheel is higher.
The IWC Big Pilots Power Reserve is a highly reliable watch which even after all these years has not lost its appeal in the slightest.
