The IWC Pilot's Watch Chronograph Spitfire (ref. IW387901) channels the tool-watch DNA of IWC’s historic aviation chronographs, pairing wartime functionality with refined in-house engineering. Taking direct design cues from the original ref. IW3706, this 2019 release updates a classic silhouette with modern mechanical depth.

Housed in a 41mm stainless steel case, the watch features a black dial with luminescent Arabic numerals, syringe-style hands, and a compact day-date display at 3 o’clock – all elements developed for ultimate legibility under cockpit conditions. Power comes from IWC’s manufacture calibre 69380, a column-wheel chronograph movement with 46 hours of power reserve, visible through a sapphire caseback. The fluted screw-down crown and domed crystal underscore its 60m water-resistance, while a military green textile strap reinforces its utilitarian intent.

Positioned within IWC’s Spitfire sub-line, the IW387901 stands out for integrating the brand’s proprietary movement into a pilot chronograph format under 42mm – a compelling option for collectors seeking mid-century aesthetics paired with 21st-century internals.
