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.

Buying guide: IWC Pilot's Watch / Fliegeruhr
Market situation and price range
At $11,583 the Pilot's Watch / Fliegeruhr sits in a segment where first owners sell regularly — clean pieces with box and papers are not uncommon. The jump from "good" to "very good" usually costs 1,000 to 2,000 euros more at purchase. You get that premium back on resale if the condition is preserved.
Where the price stands
The price has fallen by -16.3% over the past four months. No crash, but a clear downward trend. Buyers currently have room to negotiate; sellers are better off waiting for the market to bottom out — unless they have to sell.
Watch out for swings: This reference has an above-average volatility of 175.4 percent. In concrete terms: the price can move by several hundred euros within a few weeks. Check the current value before buying or selling — old listings or auction results from two months ago are of little help.
What to look out for when buying?
- Authenticity: The serial number and reference on the case must match the papers. A professional authenticity check of the IWC Pilot's Watch / Fliegeruhr reliably rules out counterfeits.
- Condition: Check scratches on the case and bezel — professional refurbishment can leave traces.
- Service history: A documented service by the manufacturer or a certified watchmaker increases the value.
- Scope of delivery: Box, papers and warranty card make a noticeable price difference on the Pilot's Watch / Fliegeruhr.
- Independent certification: The CPS-52 standard covers 52 checkpoints — from the serial number and the timing machine to water resistance. The result is secured on the blockchain and can be verified at any time.
