The TAG Heuer Carrera Chronograph 44mm Steel & Ceramic is a family of watches, not one fixed specification. For the closest black-dial steel-bracelet match, reference CBN2A1AA.BA0643, TAG Heuer lists a Calibre 16 automatic movement, 48-hour power reserve, steel-and-ceramic bezel and 100 m water resistance. The blue-dial bracelet version, CBN2A1A.BA0643, instead uses the TH20-00 movement with an 80-hour reserve. Check the reference on the watch or listing before treating any specification as universal.
Which 44 mm Carrera Chronograph is this?
The title covers several configurations in TAG Heuer’s 44 mm Carrera Chronograph range. The closest match to a black-dial steel-bracelet watch with a steel-and-ceramic fixed bezel is CBN2A1AA.BA0643. TAG Heuer also lists a blue-dial bracelet variant, CBN2A1A.BA0643, as well as green-dial bracelet and rubber-strap variants. Dial, strap and movement can differ by reference, so the family name alone is not enough to identify a specific watch.

Why the reference number changes the movement verdict
The blue-dial bracelet reference CBN2A1A.BA0643 is listed with TAG Heuer’s TH20-00 automatic movement and an 80-hour power reserve. That differs from the black CBN2A1AA.BA0643’s Calibre 16 and 48-hour reserve. Do not use one variant’s movement or reserve to describe the whole 44 mm steel-and-ceramic range.
The extra reserve on the blue version means it can remain off the wrist longer before stopping, based on the manufacturer’s stated figures. Those figures are not a comparison of independently tested performance or accuracy.
How might the 44 mm case wear?
At 44 mm, this is a substantial case on paper, but diameter alone cannot establish whether it will fit comfortably. TAG Heuer’s listing does not provide an on-wrist assessment. Try the exact reference on, paying attention to how the case sits across your wrist, whether the lugs extend beyond it, and how the bracelet or strap feels during normal movement.
Rank #2
Also inspect the actual dial and bezel in the lighting where you expect to wear it. The listed material and color do not tell you how easily you will read the chronograph or how much the crystal reflects in person.

TAG Heuer’s US listing displayed $5,600 for CBN2A1AA.BA0643, while its UK page showed £4,950 for the corresponding reference. These are market-specific prices shown on manufacturer pages accessed in 2026, not a universal price guarantee; local availability, taxes and warranty terms need checking with the relevant listing. The US page advertises a five-year warranty.
Catalog status also varies by reference: TAG Heuer’s listing for one green-dial bracelet variant, CBN2A1N.BA0643, was marked discontinued. Check the exact model’s current listing rather than assuming every dial or strap option remains available.
Rank #3
Who should consider it—and what should they verify?
This Carrera merits consideration if you want a large steel chronograph with a ceramic element in the bezel and have identified the exact dial and bracelet or strap configuration you prefer. The listed 100 m water resistance and chronograph functions make the specification sheet versatile, but they are not substitutes for hands-on fit checks or independent performance evidence.
- Confirm the full reference number, especially if the movement or power reserve is part of your decision.
- Try the 44 mm case on and assess its proportions rather than relying on diameter alone.
- Check dial legibility and crystal reflections on the actual watch.
- Verify the local price, stock status, and warranty conditions for that specific reference.
On the available manufacturer information, the strongest buying advice is to choose by reference, not just by the Carrera Chronograph name. The product listings establish specifications and displayed prices; they do not establish real-world accuracy, durability, service costs or resale value.
