Frequently asked questions

What is the lug width of the TAG Heuer Carrera CBN2018.FC6520?

The lug width (ansa) of the TAG Heuer Carrera CBN2018.FC6520 is precisely 20mm, measured between the inner shoulders of the lugs. This specification must be respected with millimetre accuracy when selecting an aftermarket strap. A narrower tolerance would create visible gaps between lug and strap; a wider tolerance would cause lateral movement of the case on the wrist. To measure correctly, use a digital calliper positioned perpendicular to the lugs, measuring from inner shoulder to inner shoulder.

Which strap is recommended for the TAG Heuer Carrera CBN2018.FC6520?

For the CBN2018.FC6520, we recommend materials that enhance the sporty-elegant character of the chronograph: structured alligator in dark tones (black, dark brown) for formal-business wear, grained calf for understated daily use, carbon or black rubber for sports and aquatic contexts, NATO in complementary colours (grey, navy) for versatility. Atelier Casati Milano offers personalised consultation with leather selection and WhatsApp updates during production, ensuring aesthetic coherence between watch and strap.

How do I change the strap on the TAG Heuer Carrera CBN2018.FC6520?

The TAG Heuer Carrera CBN2018.FC6520 uses bayonet spring bar lugs. Procedure: 1) Use a spring bar tool to apply inward pressure on the lug, freeing the mounting hole; 2) Extract the spring bar; 3) Repeat on the opposite side; 4) Insert the new strap, aligning it with the lugs, and verify the lock engages. We recommend performing this operation on a soft surface (microfibre cloth) to prevent scratches. If you lack experience, consult a certified horologist.

Is there a compatible aftermarket strap for the TAG Heuer Carrera CBN2018.FC6520?

Yes. All straps manufactured to the 20mm specification (lug width) are compatible with the CBN2018.FC6520, provided they meet the dimensional requirement. Milanostraps offers a complete collection of straps in natural leather, alligator, shell cordovan, NATO, and rubber, available in 20mm with personalisation options (length, initials, stitching thread colour). Each strap is handcrafted and accompanied by an 18-month warranty.

How long does a leather strap last on the TAG Heuer Carrera CBN2018.FC6520?

The lifespan of a leather strap depends on usage intensity, climatic conditions, and tanning quality. Quality calf leather resists 2–3 years under daily wear; vegetable-tanned alligator reaches 4–5 years; shell cordovan, with natural patina and curve, can exceed 7–10 years with minimal maintenance. Humidity is the critical factor: perspiration accelerates deterioration. We recommend rotating between at least two straps to extend longevity. Casati Milano provides exclusive maintenance guidance and can regenerate worn straps through buckle replacement or stitching renewal.
