Big Pilot’s Watch Perpetual Calendar 46.5mm

The very first IWC Pilot’s Watches of the 1930s and 1940s set technical benchmarks, and the dial designs determined the instrument look that has remained characteristic to this day.

IWC’s Big Pilot’s Watch Perpetual Calendar features a stainless steel case, a blue dial, rhodium-plated hands and a blue calfskin strap. The perpetual calendar automatically recognizes the different month lengths and the leap years, and will not require a manual adjustment until 2100. Engineered from only about 80 individual parts, the calendar module is driven by a single nightly switching pulse from the IWC-manufactured 52615 calibre.

When fully wound, the watch stores a power reserve of seven days. The elaborately decorated manufacture movement is visible through the sapphire glass back.
