Frequently asked questions

What is the lug width of the TAG Heuer Formula 1 CAZ2018.BA0970?

The TAG Heuer Formula 1 CAZ2018.BA0970 has a lug width of 20mm. This measurement represents the distance between the two spring bar attachment points on the case and determines compatibility with any aftermarket strap. It is essential to verify this specification before ordering a replacement strap, as even minor discrepancies will prevent correct installation.

Which strap is most suitable for the TAG Heuer Formula 1 CAZ2018.BA0970?

For the CAZ2018.BA0970, we recommend a strap in black or deep blue alligator, which amplifies the sports heritage without compromising versatility. Alligator maintains refined texture and ages beautifully over time. Valid alternatives include vegetable-tanned calf for a more casual appearance, or woven NATO fabric for summer use and absolute water resistance. The choice depends on predominant use and personal aesthetic preference.

How do you change the strap on a TAG Heuer Formula 1 CAZ2018.BA0970?

To change the strap, remove the lateral spring bars using a spring bar tool—a specialised instrument with a curved tip. Position the tool in the small groove beside the bar, apply downward pressure to release the bar from its position, then extract it completely. Repeat on the other side. Insert the bars into the new strap, aligning them with the case lugs and press until you feel the locking click. If you are inexperienced, the Casati Milano atelier offers professional strap change by appointment.

Are there compatible aftermarket straps available for the CAZ2018.BA0970?

Yes, Milano Straps offers a complete selection of artisanal 20mm straps compatible with the CAZ2018.BA0970, available in alligator, calf, shell cordovan, NATO and rubber. All models are customisable in length, engraved initials and choice of stitch colour. The warranty covers 18 months and work status updates are provided via WhatsApp to ensure precision in execution.

How long does a leather strap last on a TAG Heuer Formula 1?

A quality leather strap, used daily, has an average lifespan of 2-3 years before requiring replacement. Longevity depends on the material chosen: alligator and shell cordovan age more slowly than calf. Humidity, perspiration and sun exposure accelerate wear. A rubber or woven NATO strap has more predictable service cycles, resisting moisture better but requiring replacement at regular intervals. With proper maintenance and seasonal rotation, even a leather strap can last beyond three years.
