About this reference
The Pilot's Watch Chronograph IW378004 gives IWC's 43mm aviation chronograph a cool blue focus. Its stainless-steel case and bracelet frame a blue dial beneath arched-edge sapphire, while the see-through caseback makes the watch's mechanism part of the presentation. Antireflective coating on both sides of the crystal and the screw-down crown keep the active reference grounded in practical, readable design.
Automatic calibre 69385 brings chronograph timing, day, date and small seconds together through a column-wheel control system and automatic pawl winding. It offers 46 hours of power reserve, runs at 4Hz and contains 33 jewels. The 14.8mm case is rated to 100m, and the stainless-steel EasX-CHANGE bracelet gives the substantial 43mm format a useful, adaptable finish.
