IWC Schaffhausen Iw503605 Big Pilots Watch Perpetual Calendar

Owners widely praise the IWC Schaffhausen Iw503605 Big Pilots Watch Perpetual Calendar's fascinating movement and dial layout, with one owner specifically noting the comfort of its lightweight black case and another highlighting the fully synchronized perpetual calendar complication and 7-day power reserve. The watch is considered by some to be one of IWC's best, possessing great wrist presence. However, opinions diverge on its size, with some finding the 46.2mm case too large for comfortable wear, describing it as a "comedy size" that detracts from the appeal. There is also a split view on the perpetual calendar and racing green dial, with some finding them visually interesting and impressive, while others feel these features detract from a pilot's watch focus on readability and simplicity.
