IWC celebrated its 150th anniversary in 2018 with an expansive new collection that mostly focused on the classic design that has long defined the spirit of the Schaffhausen-based marque. Following that motif directly was the Big Pilot’s Watch Annual Calendar Edition “150 Years” (Ref. IW502708), which balanced IWC’S cherished pilot watch styling with the addition of an annual calendar complication to balance the dial’s appearance. IWC is no stranger to the annual calendar, having introduced it first in 2015 inside the Portugieser collection and slowly following it with various limited-edition releases in lines such as Le Petit Prince and Antoine de Saint-exupéry. The first model to bear the Big Pilot name uses the same movement, Caliber 52850, as the previous annual calendar models, displaying the month, date and day in the American format at the top of the dial. The movement uses IWC’S trademark Pellaton winding system to offer a seven-day power reserve. It comes in a stainless-steel model with an attractive blue dial and measures in at 46.2 mm. It is limited to 100 total pieces and is priced at $19,700.
