The IW377709 ran in IWC's lineup until 2022, after which Authorized Dealers spent well into 2023 clearing out their remaining stock. Collectors know the reference by several names — the 3777, the Flieger Chrono 43, the Pilot Chrono Valjoux, or simply the Pre-Manufacture Pilot Chrono. Power comes from caliber 79320, IWC's modified take on the Valjoux 7750, the movement base that had carried the entire Pilot Chrono line since the early 2000s.
## The 2022 Break
IWC retired the last Valjoux generation in 2022 with the arrival of the IW378003. In its place came the in-house caliber 69385 with column-wheel switching, along with a redesigned case and a new strap attachment. For the IW377709, that marked the end of an era that had lasted nearly two decades.
## Dial and Bezel Stay True to Form
The IW377709 shipped with a black dial and Arabic numerals, catalogued internally under the code IW377709-Dial-Black-Arabic. The bezel, fixed in stainless steel, carries the designation IW3777-Bezel-SS-Fixed. No special variant, no limited dial — and it's exactly that simplicity that makes the reference appealing to newcomers to the Pilot Chrono world, especially since it sits technically closer to classic chronograph construction than its successor.
## What This Means for Market Value
Buying an IW377709 today means buying a model with roughly 20 years of production history behind it: manufactured through 2022, available since 2023 only as leftover AD stock or on the secondary market. For ChronoCheck users, the takeaway is clear — lock in comparison values now, before the last new-old-stock pieces disappear from the market.
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.
