Serial numbers
- ? – ? (2023–?) — Breitling has used individual serial numbers per piece since 2000. Year-based serial number decoding is not publicly documented for Breitling (unlike Rolex/Omega). Known example serial number: 3399627. Serial number engraved on the case back.
Breitling introduces reference AB0145221B1P1 completely fresh for model year 2023, with no earlier AB0145 variant behind it. The Premier B01 Chronograph 42 gets five new dial colors and syringe-style hands in place of the previous baton hands. Collectors searching under nicknames like Premier B01 42, Black Premier, or Premier Chrono 42 all land on the same watch: the black-dial AB0145-221B1-Black.
## The B01 Caliber Powers Every Dial Variant
The in-house B01 caliber delivers 70 hours of power reserve across all five colorways in the MY23 lineup, from Blue (AB0145-171C1) to Silver (AB0145-211G1) to Green (AB0145-371L1). A column wheel controls the chronograph function, a vertical clutch ensures clean starts and stops, and the 1/4-second function lets you read split times to the nearest quarter second. The copper-dial version (AB0145-331K1) stands out in particular as a collector's piece, known internally as the Copper Dial Premier.
## A Fixed Bezel, Deliberately Understated
The AB0145-101 bezel is fixed and smooth, in polished steel, with no tachymeter or scale. Breitling keeps the case edge deliberately restrained across the Premier line, putting all the technical detail on the dial instead. For buyers, that means the black-dial AB0145221B1P1 is the entry point among the five 2023 colorways, technically identical to rarer versions like the Copper or Green. 2023 remains the only year this particular combination of dial, hand style, and caliber was produced under the AB0145.
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.
