The 2021 TAG Heuer Formula 1 Senna Special Edition is reference CAZ101AJ.FC6487. Its quickest visual identifier is an embossed black leather bracelet with yellow stitching and a black steel clasp. TAG Heuer identifies it as a Formula 1 chronograph in its official Senna special-editions guide.
How to identify the 2021 Senna edition
- Reference: CAZ101AJ.FC6487.
- Collection and type: TAG Heuer Formula 1 chronograph.
- Bracelet: embossed black leather with yellow stitching, finished with a black steel clasp and double safety push buttons.
The strap detail is especially useful because “Senna Special Edition” refers to several different watches. TAG Heuer’s guide describes the leather as a reference to the S/EL style Senna wore. The guide does not state a case size, price, production limit, or current availability for CAZ101AJ.FC6487.
How it differs from other Senna editions
Check the reference number before relying on a listing’s “Senna” or “Special Edition” label. TAG Heuer documents distinct configurations in nearby model years:
| Model | Movement or type | Bracelet | Documented size and other details |
|---|---|---|---|
| 2021 CAZ101AJ.FC6487 | Formula 1 chronograph; movement type not stated in the official collector guide | Embossed black leather with yellow stitching; black clasp | Case size, price, production limit, and availability not stated in the guide. TAG Heuer collector guide |
| 2022 CAZ201D.BA0633 | Automatic Calibre 16 | Steel S-shape bracelet | 44 mm; 200 m water resistance. These specifications belong to this 2022 reference. TAG Heuer brochure |
| CAZ101AX.BA0637 | Quartz chronograph | Steel bracelet | 43 mm, 200 m water resistance, and limited to 3,000 pieces, according to its separate TAG Heuer product listing. TAG Heuer product page |
TAG Heuer’s guide also lists two 2020 Senna models: CAZ201B.FC6487 and CAZ101AF.BA0637. Neither is the 2021 CAZ101AJ.FC6487.

What the 2021 reference’s specifications do—and do not—establish
The official collector guide establishes the 2021 model year, reference, Formula 1 chronograph identity, and leather-bracelet details. It does not provide a case diameter, movement caliber, water-resistance rating, price, limited-run figure, or current stock information for this reference. Do not use the specifications of CAZ201D.BA0633 or CAZ101AX.BA0637 as substitutes: they describe different watches.
Likewise, the “Shop in Store” wording on TAG Heuer’s CAZ101AX.BA0637 listing concerns that separate product page. It does not establish whether CAZ101AJ.FC6487 is available from TAG Heuer or any retailer.

What to check when comparing a listing
- Match the complete reference. Look for CAZ101AJ.FC6487 in the listing details, not just a title that says “Senna.”
- Check the bracelet description and images. The 2021 guide identifies embossed black leather, yellow stitching, and a black clasp.
- Keep specifications attached to the correct reference. A 44 mm case, automatic Calibre 16, steel S-shape bracelet, or 200 m rating is documented for the 2022 CAZ201D.BA0633—not established for the 2021 watch.
- Verify availability and condition with the seller. The official collector guide identifies the model but does not confirm present stock, price, or the details of any individual listing.
Product prices and availability are accurate as of the date/time indicated and are subject to change. Any price and availability information displayed on Amazon at the time of purchase will apply.
