IWC Pilot's Watches IW378003 43 mm Blue Dial

Blue gives the Pilot Watches IW378003 a more vivid character while retaining IWC's unmistakable aviation layout. Its 43mm stainless-steel case carries a blue dial and matching blue calfskin strap, with sapphire and a see-through caseback balancing practical protection and mechanical visibility. The screw-down crown completes an exterior that remains direct, robust and clearly shaped around the chronograph display.

Automatic calibre 69385 drives the chronograph, day, date and small-seconds indications, with a column-wheel control system and automatic pawl winding. The movement beats at 4Hz, contains 33 jewels and stores 46 hours of power reserve. At 14.8mm thick and rated to 100m, the active reference has real wrist presence, while the 21mm lug width gives the blue leather strap appropriate scale.
