FAQ

What is the lug width of the TAG Heuer Carrera CBN2015.BA0642?

The lug width of the TAG Heuer Carrera CBN2015.BA0642 is 20mm. This width is specific to the 42mm Carrera models featuring integrated bracelets and is compatible with all artisanal straps certified for this measurement. To measure correctly, place a digital calliper perpendicular to the longitudinal axis of the case, from the inner left margin to the inner right margin of the attachment shoulder.

Which strap is best suited for the TAG Heuer Carrera CBN2015.BA0642?

For the CBN2015.BA0642, we recommend an alligator strap with pronounced vertical grain, which emphasises sportiness without compromising the model's inherent elegance. Alternatively, taurine leather of high quality tanned traditionally guarantees a patina that evolves over time, whilst shell cordovan offers superior durability and tactile memory. For aquatic environments, vulcanised rubber resists thermal variation and moisture.

How do I change the strap on the TAG Heuer Carrera CBN2015.BA0642?

To change the 20mm lug strap, it is necessary to remove the lateral pressure springs that secure the lugs to the case attachment pins. Use a dedicated tool to gently release the spring, extract the old lug from the side, align the new strap to the pins, and reposition the spring until it clicks into place. It is advisable to have this operation performed by a professional watchmaker to avoid damage to the case finish.

Can I use aftermarket straps compatible with the TAG Heuer Carrera CBN2015.BA0642?

Yes, Milano Straps supplies artisanal aftermarket straps in 20mm size fully compatible with the CBN2015.BA0642. All our straps are verified for tolerances and fit, customisable in leather, colour, initials and stitching thread. Warranty is 18 months through the Casati Milano atelier, which also offers assistance with measurements and updates.

How long does a leather strap last on the TAG Heuer Carrera CBN2015.BA0642?

Durability depends on material and daily use. A high-quality alligator strap lasts 3-5 years with routine maintenance; taurine leather guarantees 2-4 years, whilst shell cordovan, thanks to its natural compactness, can exceed 5 years. Exposure to moisture, excessive heat and friction reduces longevity. Milano Straps recommends periodic cleaning with a soft dry cloth and storage in a controlled environment.
