The movement has a column-wheel architecture for the control of the chronograph functions.

Frequently asked questions

What is the lug width of the TAG Heuer Carrera CBG2011.FC6430?

The lug width of the TAG Heuer Carrera CBG2011.FC6430 is 20mm. This dimension is specific to this model and represents the standard chosen by TAG Heuer for this generation of Carrera. It is essential to respect this measurement within minimal tolerance to maintain the aesthetic balance and mechanical stability of the strap.

Which strap is recommended for the TAG Heuer Carrera CBG2011.FC6430?

For the CBG2011.FC6430, we recommend alligator straps with regular geometric grain for a timeless classic look, or vegetable-tanned calf leather if you desire a softer texture and natural patina development over time. For intensive sporting use, an FKM rubber strap in high density offers excellent grip and water resistance, whilst NATO fabric provides informal versatility without compromising the motorsport DNA.

How do I change the strap on a watch with 20mm lugs?

Changing the strap on a 20mm lug-width watch involves removing the spring bars that secure the strap to the lugs. Use a dedicated spring bar tool to depress the bar inward into the case, creating space to remove the old strap. Insert the new strap, aligning the holes with the lugs, then reinsert the spring bars until they click into place. Verify that the strap is stable and free from lateral movement.

Can I use an aftermarket strap on a TAG Heuer Carrera 43mm?

Yes, provided the strap is certified for the 20mm lug width. Quality aftermarket straps maintain the same dimensional tolerances as original straps and guarantee mechanical and aesthetic compatibility. Choose specialised suppliers who understand the geometric constraints of integrated Carrera cases and can customise the strap according to your material, colour, and finish preferences.

How long does a leather strap last on a wristwatch?

The lifespan of a leather strap depends on usage and tanning method. An alligator or vegetable-tanned calf strap, under average daily use and with proper maintenance, typically lasts between 3 and 5 years. Humidity, perspiration, and prolonged sun exposure accelerate ageing. Rotating between multiple straps extends the service life of each. Artisanal quality straps guarantee 18 months of coverage against manufacturing defects.
