Up for sale is the IWC Big Pilot's Watch Annual Calendar Spitfire in excellent pre-owned condition. In a history going back over 80 years, the Pilot’s Watch family has spawned many models that have long been among IWC’s most iconic models. The Big Pilot’s Watch is one of them – the uncluttered, classically simple dial and triangular index at “12 o’clock”, both typical features of the Pilot’s Watches, are unmistakably modeled on the 1940 original. This BP Annual Calendar was introduced in 2016, pairing IWC's new(-er) annual calendar caliber with the Big Pilot case. The annual calendar shows the month, date and day in three separate windows. The mechanism automatically takes into account the differing lengths of individual months. Unlike a perpetual calendar, however, the annual calendar is unable to make allowance for the leap days in February or the leap years. Once a year, then, at the end of February, it requires manual correction. In the case of IWC’s annual calendar, the correction is made simply, via the crown.
