The IWC IW387901 goes by several names in the market: "Spitfire Chrono," "Spitfire Chrono 41," occasionally "Pilot Spitfire Steel" — depending on who you ask. The reference itself is fairly unambiguous: 41 millimeters of steel, pilot chronograph, inspired by the Supermarine Spitfire that became the most iconic British fighter of World War II from 1936 onward. IWC didn't invent this connection — they've been building on it methodically since the early 2000s.
## The Market Knows This Watch Better Than Its Name
On Chrono24 and across the secondary market, the IW387901 currently trades between 4,800 and 6,200 euros — depending on condition, papers, and whether the original box is included. That's a premium of roughly 15 to 20 percent over what buyers were paying three years ago. Not because the watch has suddenly become scarcer, but because buyers have caught on: a steel pilot watch with an in-house movement and a clean design language doesn't lose its footing in a portfolio.
## Why 41 mm Is No Accident
IWC staked out this case size deliberately, landing between the classic 40 mm dress watch and the 43 mm sport model. On the wrist, the watch wears universally — that's not marketing copy, it's something you feel after 20 minutes. The sapphire caseback puts the manufacture caliber on display, which at an entry price under 6,000 euros is anything but standard. Anyone familiar with the Spitfire line will recognize the pattern: IWC left very little here to chance.
Brand profile: IWC
IWC Schaffhausen produces high-quality pilot and sports watches. The Portugieser, Pilot's Watch (Big Pilot + Mark XVIII/XX), and Portofino are the most frequently faked references. Since 2025, APS Factory V3 has produced integrated 52010 super-clones with correct case thickness — classic tells (case thickness, movement visibility) are only partially reliable against these. Key checks today: engraving depth, seconds tick interval, thermally blued hand color, and sub-dial proportions.
- Serial number: genuine IWC serials are 6 digits, purely numeric, on the caseback — all serial numbers are verifiable in the IWC 'My IWC' portal. Fakes often have 7 digits or a mix of letters and numbers.
- Portugieser sub-dial seconds intervals: a GENUINE piece has exactly 3 mini-ticks between each seconds index (high beat rate of 28,800 vph) — fakes have 4 or irregular ticks (lower beat rate).
- Caseback engraving 'International Watch Company': genuine engraving is DEEP (perceptible with a fingernail) and sharp-edged — fakes are shallower, sometimes just laser-printed rather than truly engraved. Test: raking light and a loupe.
- Portugieser/Portofino blue hand color: thermally blued steel shifts from deep blue to light violet depending on viewing angle — painted fake hands show a flat, uniform blue.
Serial number format: IWC serial numbers: 6-digit numeric on the caseback. Verifiable online via the IWC My IWC Portal.
