IWC IW502618 Big Pilots Perpetual Calendar SS Black Dial

The IWC Big Pilot’s Watch Perpetual Calendar Limited Edition ref. IW502618, introduced circa 2010, represents a rare boutique-exclusive release with only 250 pieces ever produced. Housed in a commanding 46.2 mm stainless steel case with a thickness of approximately 15.8 mm, it showcases IWC’s in‑house calibre 51614 automatic movement with a seven‑day (168‑hour) power reserve and Pellaton winding system. The black dial is enlivened by bold orange hands and indices, complemented by a perpetual calendar that displays the day, date, month, four‑digit year, and moon phases for both hemispheres. Water‑resistant to 60 meters (6 bar), this model balances technical sophistication with practicality. The transparent sapphire caseback reveals the finely finished movement and rotor engraved “ONE OUT OF 250,” underscoring its limited-edition status. Offered on a black alligator leather strap with striking orange stitching, the watch merges pilot‑watch robustness with haute horlogerie complexity. For collectors, this edition stands out not only for its scarcity but for its masterful integration of a perpetual calendar in the iconic Big Pilot format, making it a compelling addition to any advanced IWC collection.
