What I'm asked about the TAG Heuer Carrera CAS2150.BD0731

What strap size does the TAG Heuer Carrera CAS2150.BD0731 take?

The TAG Heuer Carrera CAS2150.BD0731 needs 20 mm between the lugs, usually 16 mm at the buckle. It's the size I've been fitting on it for years.

Can the strap on the TAG Heuer Carrera CAS2150.BD0731 be changed?

Yes. It has spring bars between the lugs: with the right tool the strap comes off in a minute. If you'd rather not risk a scratch, I do it in the workshop.

Can I put a leather strap on the TAG Heuer Carrera CAS2150.BD0731?

Yes, in 20 mm leather. On a 41 mm chronograph I like box calf: it holds its shape and carries a substantial case.

Which strap do you recommend for the TAG Heuer Carrera CAS2150.BD0731?

A 20 mm box calf. You'll find it ready in the 20 mm collection. If you'd rather have something built on your wrist, the Casati atelier.

The Carrera CAS2150.BD0731, seen from the bench

The Carrera represents one of the historic collections of TAG Heuer, characterized by chronograph functions dedicated to the automotive world. This model mounts the automatic Calibre 16 movement with hours, minutes, small seconds, date, and chronograph. The CAS2150.BD0731 reference maintains the classic design of the Carrera line with essential complications for time measurement.

Frequently asked questions

Which strap is best suited for the TAG Heuer Carrera CAS2150.BD0731?

For a two-tone Carrera in stainless steel and yellow gold, we recommend straps in natural alligator or superior calf leather, which enhance the sporty elegance of the model. Alligator, with its geometric and regular grain, pairs beautifully with the aesthetic contrast of the case. For more versatile use and resistance to the elements, a robust NATO or FKM rubber strap offers practicality without compromising the identity of the chronograph.

Can I use an aftermarket strap on the TAG Heuer Carrera CAS2150.BD0731?

Yes, it is entirely possible to use an aftermarket strap compatible with a 20 mm lug width. Many artisanal strap manufacturers offer high-quality solutions, made to measure or from catalogue, that guarantee excellent construction standards, premium materials and customisation. Before purchasing, always verify that the lug width is exactly 20 mm and that the strap is designed for watches with a 41 mm case.

How long does a leather strap last on the TAG Heuer Carrera CAS2150.BD0731?

The lifespan of a leather strap varies depending on the material, frequency of use and maintenance. A high-quality artisanal alligator or calf strap can last 5–8 years with regular use and occasional cleaning. A less noble leather or one used in extremely humid conditions may show signs of ageing more quickly. However, natural patina is part of the character of leather and represents the passage of time. Proper maintenance—avoiding prolonged immersion and drying the strap after exposure to moisture—significantly extends longevity.
