IWC Schaffhausen Iw329602 Big Pilots Watch Perpetual Calendar ProsetvsZenith Pilot Big Date Flyback

Owners and reviewers widely praise the IWC Schaffhausen Iw329602 Big Pilots Watch Perpetual Calendar Proset for its innovative crown-operated perpetual calendar adjustment, which allows for both forward and backward setting and eliminates the need for corrector buttons. The 42mm case size is noted as more wearable than previous Big Pilot models, and the Bordeaux and gold color scheme is described as striking by some. However, opinions are divided on the dial's legibility, with some finding the maroon and gold combination busy and others appreciating the complications. Some owners find the watch too large for wrists under 7 inches, with lug overhang being a concern, and a few commenters dislike the appearance of the moon phase indicators. The watch has 100m water resistance and a 60-hour power reserve.

Owners and reviewers widely praise the Zenith Pilot Big Date Flyback's flyback chronograph execution—the column-wheel mechanism exhibits exceptionally smooth button action and activates with a super light touch—and applaud its functional pairing of high-frequency chronography with an instant big-date complication, particularly valued by pilots. The corrugated dial, lume-filled numerals, and striking case finishing (notably the cerulean blue ceramic variant) earn consistent appreciation, and the watch wears more compact than its 42.5mm dimensions suggest despite its ~14.5mm thickness. The El Primero 3652 movement delivers a 60-hour power reserve and 5Hz frequency, and the exhibition caseback showcases the mechanism beautifully.
