IWC Schaffhausen Pilot’s Watch Chronograph 41

IWC Schaffhausen's Pilot's Watch Chronograph 41, reference IW388101, has a stainless steel case measuring 41 mm across. The case stands 14.5 mm thick and carries a screw-down crown. A self-winding movement, calibre 69385, drives the watch and runs with 46 hours of power reserve. The blue dial sits under a convex sapphire crystal with anti-reflective coating on both sides, and a sapphire window on the back allows a view of the movement. As a chronograph, this piece combines that function with small seconds, a date display and a weekday indicator. Water resistance is rated to 100 metres. IWC fits this reference with a blue calf leather strap, fitted with IWC's quick-change system.
