Serial numbers
- ? – ? (2017–?) — Modern Breitling uses random serial numbers; the production year cannot be derived from the serial number. Dating feature: 4-digit WWYR code (week + 2-digit year) engraved between the lower case lugs, e.g. '0317' = week 3, 2017.
The Superocean Heritage B20 Automatic 42 launched in 2017. Breitling fitted the Tudor-developed MT5612 — badged internally as Caliber B20 — rather than an in-house movement, a choice that initially met skepticism from the market yet earned the caliber a loyal following. 42 mm in diameter, polished ceramic bezel, and more dramatically raked lugs than its direct predecessor, the A17312. With that new case geometry, Breitling drew a clear line between generations.
## Why This Particular Dial Drives Secondary-Market Demand
The dial on reference AB2010121B1A1 comes in Blue Sunray, and that is no incidental detail. Across the Heritage line, buyers skew heavily toward blue dials; the silver variants consistently sit on the market longer. Caliber B20's silicon escapement and 70-hour power reserve stand as arguments in their own right — the movement is robust to service and backed by an established Tudor service record that prospective buyers can readily assess.
## What the AB3111 Transition Means for This Generation
Since 2025, Breitling has been transitioning the Heritage line to the AB3111: manufacture Caliber B31, 120 hours of power reserve, 120 clicks on the bezel versus the 60 of the B20 generation. The AB2010 is now a closed model. That status, as the market has shown time and again, initially creates price pressure before rising collector demand closes the gap. Current transaction data for the AB2010121B1A1 is available on ChronoCheck.
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.
