The Big Pilot’s Watch Annual Calendar Edition “150 Years” is available in a limited edition of 150 watches. It features a stainless steel case, a blue dial with a lacquered finish, and rhodium-plated hands. The IWC-manufactured 52850 calibre’s Pellaton winding system is fitted with virtually wear-free ceramic components and uses two barrels to generate a power reserve of 7 days. The movement and the rotor with an inlaid Jubilee medallion can be viewed through the see-through sapphire-glass back. The timepiece is equipped with an annual calendar; this convenient complication has an American-format display for the month, date and day in three separate windows on the dial, and requires adjustment only once a year at the end of February.
