Carrera CAR2A1AB.FT6163— lug 20mm

The lug width of the TAG Heuer Carrera CAR2A1AB.FT6163 is 20mm. This dimension is critical for aftermarket strap compatibility: any replacement strap must respect this exact measurement to mount correctly on the case lugs without play or misalignment. Always verify the lug width by measuring the distance between the two horizontal pins that traverse the case lugs.

Four primary materials are recommended for the Carrera. Alligator is the formal choice par excellence: natural grain is minimal and does not compete with the chronograph's visual density. Vegetable-tanned calf offers natural ageing and develops patina over time. Shell cordovan from equine croup generates unique organic lustre. NATO in cotton serge is ideal for summer configurations. Avoid pure rubber unless frequent aquatic immersion is required, as it flattens the aesthetic hierarchy of the piece.

Strap replacement is achievable with a spring bar tool (ring or fork-type implement) introduced horizontally beneath the case lug to compress the pin's spring retainer. Apply uniform pressure from both sides, removing the old strap. Position the new strap—with lugs oriented toward the case's diametral axis—and reinsert the pins until the retainers engage their sockets. Verify there is no residual play. If unfamiliar with this procedure, Casati Milano's atelier offers this service in person at their Milan location.

All straps with a 20mm lug width are compatible, provided they respect the attachment configuration (pin or cartridge). Milano Straps offers a dedicated collection of 20mm straps in alligator, natural calf, shell cordovan and technical textiles, all available online with personalisation of length, initials and thread colour. Compatibility is guaranteed by strict respect of lug width; however, always verify your case number with an authorised TAG Heuer retailer before ordering.

A leather strap's lifespan depends on material and usage. Quality alligator, used with moderate care (not in stagnant fresh water), lasts between 3 and 5 years. Vegetable-tanned calf resists 2-3 years under normal conditions, but develops aesthetic patina some collectors prefer to virgin appearance. Shell cordovan has greater longevity (5-7 years) due to fibre density. Typical wear manifests as internal stitching separation at lateral creases. Store the strap in a dry environment and avoid prolonged exposure to extreme humidity or heat. Casati Milano offers an 18-month warranty on its handcrafted straps and provides restitching service.
