Serial numbers
- ? – ? (2023–?) — Modern Breitling watches (post-2009) use a 4-digit production date stamp system between the lugs at 6 o'clock (format: 'WWYY' — first 2 digits = calendar week, last 2 = year). No public traditional serial number year charts available.
Among Breitling collectors, reference A233802A1L1A1 goes by four names at once — Curtiss Warhawk, Warhawk, P-40 Warhawk, and Classic AVI Warhawk. Four names for one and the same watch, which says a lot about how firmly this model has lodged itself in collector memory. The name traces back to the Curtiss P-40 Warhawk, the iconic fighter plane famous for its painted shark-mouth nose. With the ClassicAVI line, Breitling poured that exact aviation history into watch form, and the A233802A1L1A1 is one of its clearest expressions.
## A Green Dial With Its Own Code
Internally, Breitling files the dial under the code A233802-L1-Khaki-Warhawk, known to collectors as Warhawk Green. Khaki instead of the usual black or white is a rare choice for ClassicAVI models, making this dial variant one of the most visually distinctive in the series. It's paired with a bezel carrying the code ClassicAVI-42-Ratchet-12H-Steel. The 42 in the code points to the case size, while 12H denotes the hour scale with its ratcheting mechanism — the kind familiar from military pilot's watches.
## The Caliber Under the Hood
Powering the Warhawk is the Caliber 23 ND. No showy modules, no complication for complication's sake — just a movement built to match the pilot's-watch philosophy: rugged, legible, stripped down to essentials. It's exactly this combination — khaki dial, ratchet bezel, and the 23 ND caliber — that makes the A233802A1L1A1 a reference collectors chase not for a rare complication, but for the coherent story that dial, bezel, and name tell together.
Brand profile: Breitling
Breitling is known for aviation and dive watches. Chronographs (Navitimer, Chronomat) are the most frequently counterfeited. Pay close attention to slide rule details and COSC certification.
- Wing logo: a genuine Breitling logo shows the anchor and wing tips that NEVER touch — precise negative space between them — fakes let the tips meet or overlap
- 3D 'B' crown: the 'B' on the crown must appear three-dimensional with a light reflection on the curve — a flat 'B' = fake
- Bezel scale vs. dial: the outer white bezel scale must align precisely with the inner black dial indices — fakes show misalignment
- Date disc depth: a genuine Navitimer date disc sits flush with the dial plane — fakes show the date window as a 'crater' (noticeably sunken or raised)
Serial number format: Breitling serial numbers: alphanumeric, located between the lugs at 6 o'clock. Format: one letter + 8 digits (e.g. 'AB012012'). Older models: digits only.
