IWC Schaffhausen Iw329602 Big Pilots Watch Perpetual Calendar Proset

The IWC Schaffhausen Iw329602 Big Pilots Watch Perpetual Calendar Proset is widely praised for its innovative crown-operated perpetual calendar adjustment, allowing for both forward and backward setting without correction pushers. Owners and reviewers highlight the mechanical refinement of the calendar module, integrated into the automatic movement, and the improved 100-meter water resistance. Some find the 42mm case size a welcome downsizing for the Big Pilot line, with the stainless steel variant on a five-link bracelet and swappable rubber strap noted as a practical everyday option. However, opinions are divided on the dial's readability and busyness, with some criticizing the oversized crown's aesthetics on certain models and the moon phase indicators' appearance. Some owners also find the watch too large for regular wear, despite the 42mm dimension.
