The Pilot IW3718-10 (aka: IW371810, 371810), seen from the bench

The Pilot's Watch Chronograph IWC IW3718-10 is a sophisticated aviation instrument featuring a 44mm 18-karat red gold case and IWC caliber 79420 movement with rattrapante chronograph function. The 20mm lug width integrates harmoniously with the case proportions, while the approximately 15.5mm thickness maintains elegance despite the substantial diameter. This chronograph represents the contemporary evolution of IWC's Pilot watch tradition, combining modern technical mastery with refined construction.
