The Carrera CAR5A80.FC6377, seen from the bench

The TAG Heuer Carrera CAR5A80.FC6377 is a chronograph featuring a hybrid case in titanium and stainless steel with a 45mm diameter and 20mm lug width. It houses the Heuer 02T caliber, a chronometer-certified movement with column-wheel chronograph and tourbillon escapement, ensuring precision of ±5 seconds per month. The sapphire crystal with anti-reflective coating protects the racing dial, while water resistance reaches 100 meters. This contemporary evolution of the iconic Carrera collection combines lightweight titanium on the external bezel with stainless steel on the case back.

Frequently asked questions

What is the lug width of the TAG Heuer Carrera CAR5A80.FC6377?

The lug width is 20mm. This measurement is standard for the CAR5A80.FC6377 model and cannot be modified. To verify it, measure the internal distance between the lugs with a digital caliper: you will obtain exactly 20mm. Always ensure the aftermarket strap is compatible with this measurement before purchase.

Which strap is most suitable for the TAG Heuer Carrera CAR5A80.FC6377?

For this chronograph, we recommend naturally tanned leather of the highest standards: genuine alligator with natural texture for a sophisticated look, or English calf with fine grain if you prefer versatility. Alligator enhances the technical vocation of the watch, whilst calf offers a compromise between formality and sportiness. Avoid low-quality synthetics; a chronometer-certified movement deserves excellence in leather.

How do I change the strap on my TAG Heuer Carrera CAR5A80.FC6377?

Remove the spring bars (lever-shaped tools) from the lugs of the case, gently prying to extract the pins that secure the strap to the lugs. Once the old strap is freed, align its lugs with those of the case and reinsert the pins, securing them firmly. If the lug geometry is non-standard, entrust the change to Casati Milano atelier for professional handling.

Can I use aftermarket straps on the TAG Heuer Carrera CAR5A80.FC6377?

Yes, but it is essential to verify the compatibility of the lug width (20mm) and the attachment geometry. Not all universal straps fit perfectly to this model. On milanostraps.it you will find tested and compatible 20mm straps, ready for shipment. For bespoke solutions and non-standard attachments, contact Casati Milano atelier.

How long does a natural leather strap last on a watch like the TAG Heuer Carrera CAR5A80.FC6377?

A quality leather strap, subject to regular maintenance, lasts 3–5 years in daily use. Alligator and shell cordovan are among the most durable, resisting continuous flexing. Longevity increases if you expose the leather to moderate humidity and clean it regularly with a soft brush. Casati Milano offers an 18-month guarantee and services for regenerating aged leather.
