The IWC Big Pilot’s Watch Perpetual Calendar Top Gun combines the seven day power reserve found in IWC’s Big Pilots watches, with what we think is the grandest of all complications, the Perpetual Calendar.
The typical watch has enough reserve power to run 2 to 3 days without needing to be recharged by winding or the natural movement of the arm which winds automatic watches making the IWC’s 7-day power reserve more than a cut above the standard.
The perpetual calendar function removes the need to be adjusted every other month and takes into account that some months have 28 days and 30 days rather than 31 days, and also accounts for leap years. The movement in the IWC Big Pilot’s Watch Perpetual Calendar Top Gun will not pose an issue until the year 2100, a year that breaks with the conventional four-year cycle and will not be a leap year.
The 48 mm case is made out of a combination of ceramic and titanium and is finished with a soft synthetic material strap.
