The Premier B25 Datora 42, reference AB2510201K1P1, launched in 2021 and brought Breitling back a complication that had been missing from the catalog: the Datora, meaning a full calendar with moon phase and chronograph in a single caliber. Collectors know the model under three names — Copper Datora, Salmon Datora, Heritage Datora — depending on how the copper-toned dial catches the light.
## A case that quotes four decades
The B25 caliber sits inside a modern Premier case that nods visually to the seventies. Lance-style hands, a fluted case border, and a sapphire caseback showing off the movement all echo the original Premier line. Arabic numerals in place of indices round out the vintage look. Alongside the steel version, 2021 also saw the release of an 18-karat red gold model with a silver dial, reference RB2510371G1P1 — the pricier sibling from the same launch.
## Four years on, a Singapore special edition proves the design still resonates
In 2025 Breitling followed up with a limited run marking the 60th anniversary of Singapore's independence: 60 pieces of reference AB25101A1K1P1, dial in burgundy, priced at S$20,950 including GST, sold exclusively in the city-state. The foundation stayed the same B25 Datora construction as the 2021 original — only the dial color sets the editions apart. For the AB2510201K1P1 itself, that means a case concept now backed by four years on the market and established as a distinct variant within the Premier family.
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.

Market situation and price range
At $12,245 the Premier B25 Datora 42 sits in a segment where first owners sell regularly — clean pieces with box and papers are not uncommon. The jump from "good" to "very good" usually costs 1,000 to 2,000 euros more at purchase. You get that premium back on resale if the condition is preserved.
Watch out for swings: This reference has an above-average volatility of 44.2 percent. In concrete terms: the price can move by several hundred euros within a few weeks. Check the current value before buying or selling — old listings or auction results from two months ago are of little help.
