The Navitimer 1 B01 Chronograph 46 launched on February 6, 2019 as the AB0127 – flat sapphire crystal, no AOPA emblem, fully polished case. Three years later, in April 2022, Breitling rolled out the complete MY22 redesign: the AB0127 became the AB0137. The AOPA emblem is back, the sapphire crystal is now domed instead of flat, and the slide rule scale was flattened. Despite the identical 46mm case size, the watch wears noticeably slimmer on the wrist than its predecessor. The finishing shifted from all-polished to a mix of polished and brushed surfaces, and the date window moved to the 6 o'clock subdial.
## Green Navi: the Ref. AB0137241L1A1 in detail
Our reference AB0137241L1A1 carries the AB0137-241L1-Green-Sunburst dial, one of three new MY22 colorways alongside copper and light blue – collectors know it as the "Green Navi." Inside the case beats the in-house B01 caliber, the same manufacture movement that debuted in the AB0127 back in 2019. The steel Navitimer slide rule bezel remains the functional heart of the line, unchanged across both generations.
## Why "Big Navi" is more than a nickname
At Breitling, 46mm marks the large execution alongside 41mm and 43mm, hence the collector nickname "Navi 46" or "Big Navi." Anyone who's held an AB0137 next to a 2019 AB0127 immediately notices why the domed crystal was never just a cosmetic tweak. With identical case dimensions, the visual slimming makes the leap between the two generations obvious the moment you pick one up, not just on paper.
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.
