Serial numbers
- ? – ? (2020–?) — Modern Breitling watches (from around 2010 onward) no longer carry a classic serial range. Dating is done via an engraved date code in the format WWYR (2-digit week number + 2-digit year, e.g. '4220' = week 42 of 2020) between the lower lugs – readable after removing the strap.
The A10380101C1A1 is the configuration with a smooth rider-tab bezel and blue baton dial — and the entry point into a reference system that Breitling has built out with real consistency across the Chronomat 36. Nine dial variants, three bezel configurations, one calibre. Anyone who knows this ref understands the logic behind it.
## Calibre B10 — Breitling's In-House Answer to the Movement Debate
Calibre B10 is a COSC-certified chronometer, developed and manufactured by Breitling. 38 hours of power reserve, automatic winding, ±4 seconds per day as the tolerance threshold — that's not a marketing claim, that's the COSC certification. For a 36 mm case, the technical specification is genuinely solid.
## Nine Dials, Three Bezels — Building One Reference for Nine Buyer Profiles
What Breitling has done with the A10380 is unusually thorough for the segment: the range runs from the understated Silver Dial through Mint Green and South Sea Midnight Blue all the way to the fully set South Sea variant with gem-set bezel. The latter retails at roughly 35 to 40 percent more than the base version. Anyone buying or valuing an A10380 therefore needs to read the dial code and bezel code together — the reference number alone doesn't tell you enough here.
## What the Market Does with This Reference
The Chronomat 36 trades pre-owned between approximately $3,734 and $8,052 depending on diamond setting, dial variant and condition. South Sea bezel examples hold their value more steadily — demand for fully set pieces remains consistent, even if trading volume stays modest.
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.
