About this reference
Titanium gives the Pilot Watches IW377903 a lighter visual and material expression of IWC's chronograph-led aviation design. The black dial fills a 43mm case, with a black calfskin strap preserving the purposeful monochrome palette. Sapphire protects the display, while the see-through caseback brings the movement into the composition and the screw-down crown keeps the exterior firmly functional.
Automatic calibre 69385 provides chronograph timing, day, date and small seconds, using a column-wheel control system and automatic pawl winding. Its 33 jewels, 4Hz frequency and 46-hour power reserve support a technically serious specification. The discontinued case measures 14.8mm thick and carries 60m water resistance, giving the XL watch a strong, substantial stance on the wrist.
