It is one model in a Senna Formula 1 family that also includes automatic alternatives, so the reference number matters when comparing specifications or prices.
Which TAG Heuer Senna Formula 1 chronograph is this?
The closest match to the product name is the Formula 1 Chronograph x Senna, reference CAZ101AJ.FC6487. TAG Heuer presents it as a special-edition racing chronograph honoring Ayrton Senna and the brand’s partnership with the Senna Foundation.
“New” in a headline does not establish a recent release date. TAG Heuer’s official magazine chronology identifies this specific black-strap model as a 2021 release. The brand says Senna Formula 1 models launched in 2020 in both automatic and quartz chronograph variations, and identifies a red-accented Formula 1 Senna release in 2022. Those dates refer to a wider family, not a single watch.
CAZ101AJ.FC6487: specifications and design
This reference combines a black dial and 43 mm black DLC-coated steel case with a fixed steel-and-ceramic bezel. Its black calfskin strap uses a Senna S-link motif, a design reference to the S/EL bracelet Senna wore; the clasp is sand-blasted steel and folding.

| Specification | CAZ101AJ.FC6487 |
|---|---|
| Movement | Quartz |
| Case | 43 mm black DLC-coated steel |
| Bezel | Fixed steel and ceramic |
| Dial and strap | Black dial; black calfskin strap with Senna S-link motif |
| Clasp | Sand-blasted folding clasp |
| Chronograph and display functions | 1/10-second chronograph, seconds, 30-minute counter and date |
| Water resistance | 200 m, according to TAG Heuer’s product specification |
The 1/10-second chronograph and 30-minute counter are the listed timing functions; the date and seconds complete the stated display functions. The design reference to the S/EL bracelet is expressed through the strap motif rather than a steel bracelet.
How the quartz and automatic Senna Formula 1 watches differ
“Senna Formula 1” covers multiple references. A documented automatic comparator is CAZ201D.BA0633, a 44 mm Calibre 16 chronograph with a fine-brushed steel S-shape bracelet and black ceramic tachymeter bezel. TAG Heuer’s 2022 brochure lists hours, minutes, seconds and chronograph functions for that model.

| Reference | Movement | Case | Bracelet or strap and bezel | Functions / water resistance |
|---|---|---|---|---|
| CAZ101AJ.FC6487 (2021) | Quartz | 43 mm black DLC-coated steel | Black calfskin strap with Senna S-link motif; fixed steel-and-ceramic bezel | 1/10-second chronograph, seconds, 30-minute counter, date; 200 m |
| CAZ201D.BA0633 (listed in 2022 brochure) | Automatic Calibre 16 | 44 mm; material not stated in the cited 2022 brochure | Fine-brushed steel S-shape bracelet; black ceramic tachymeter bezel | Hours, minutes, seconds and chronograph functions; 200 m |
The difference is not simply quartz versus automatic: the documented watches also differ in size, bracelet or strap, bezel and stated functions. Check the reference number rather than assuming every Senna Formula 1 has the same movement or design. The 2025 Formula 1 Chronograph collection article describes 44 mm grade 2 titanium cases, black DLC coatings and rubber straps, but does not identify those watches as Senna editions; those specifications should not be attributed to CAZ101AJ.FC6487.

What to check before choosing a reference
- Reference and date: Confirm the model number. CAZ101AJ.FC6487 is dated 2021 by TAG Heuer; “New” alone does not date a release.
- Movement and functions: Decide whether you want the quartz CAZ101AJ.FC6487 and its specified 1/10-second timing functions, or an automatic option such as CAZ201D.BA0633 with Calibre 16.
- Fit and materials: Compare the 43 mm black DLC-coated case and calfskin strap with the 44 mm automatic comparator’s steel bracelet. Case size is only one part of fit; try the watch if possible.
- Design: The CAZ101AJ’s S-link reference appears in its strap motif; CAZ201D.BA0633 uses an S-shape steel bracelet and ceramic tachymeter bezel.
- Purchase terms: Verify local price, stock, warranty and purchase channel directly with TAG Heuer or a retailer before placing an order.
