IWC Schaffhausen Pilot's Watch Chronograph

The IWC Schaffhausen Pilot's Watch Chronograph IW378003 has a stainless steel case measuring 43 mm across. The case stands 14.8 mm thick, and the crown screws down against the case. 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 antireflective coating on both sides, and the case has a display back. This chronograph combines date and weekday displays with small seconds and hour, minute and second timing counters. Water resistance is rated to 100 metres. IWC specifies a blue calf leather strap, fitted with IWC's EasX-CHANGE quick-change system.
