IWC Big Pilot's Watch Perpetual Calendar

About this reference

The IWC Big Pilot’s Watch Perpetual Calendar reference IW5036-05 was introduced in 2021 as a core collection model and remains in current production. This reference is distinguished by its combination of a 46.2mm stainless steel case and a sunray-finished blue dial, a pairing previously reserved for limited editions like the "Le Petit Prince" series. It utilizes the IWC-manufactured caliber 52615, an automatic movement featuring a Pellaton winding system, ceramic components, and a seven-day power reserve via twin barrels. The perpetual calendar complication, originally engineered by Kurt Klaus, displays the date, day, month, and year in four digits, alongside a double moon phase for both hemispheres. On the secondary market, this reference typically trades between $22,000 and $28,000. While not a limited production, it represents the first time this specific blue and steel configuration entered the permanent Big Pilot catalog without boutique-exclusive branding.
