IWC Schaffhausen Iw329602 Big Pilots Watch Perpetual Calendar Proset

IWC Schaffhausen Iw329602 Big Pilots Watch Perpetual Calendar Proset owners and reviewers widely praise its innovative crown-operated perpetual calendar adjustment, which allows for bidirectional setting without correctors, simplifying operation. The 42mm case size is noted as making the complication more accessible, and the watch features a highly precise moon phase display accurate to one day in over 1000 years. Some owners find the Bordeaux and gold color scheme striking, while others criticize its readability as a pilot's watch, likening the moon phase indicators to "googly eyes" and feeling that covered hour numbers detract from simplicity. Several commenters noted the watch appears too large for many wrists, and one mentioned setting the perpetual calendar can be a struggle. On balance, owners and reviewers rate the IWC Schaffhausen Iw329602 Big Pilots Watch Perpetual Calendar Proset highly for its user-friendly perpetual calendar mechanism and more accessible 42mm case size.
