Strap for Carrera Calibre Heuer 01 45 Stainless Steel / Skeleton / Alligator / Manchester United

The lug width of the TAG Heuer Carrera CAR2A1J.FC6400 is 20mm. This dimension is determined by the case geometry at 45mm and defines the space between the two side lugs where the strap is positioned. It is essential to verify this measurement before purchasing an aftermarket strap, as straps with a different width, even by just 2mm, will not fit correctly.

For the Carrera CAR2A1J.FC6400, we recommend alligator or dark calf leather straps for everyday elegance. Alligator creates sophisticated visual contrast with the ceramic and steel case, whilst calf offers a patina that evolves naturally over time. For intense sports activity, an FKM rubber strap ensures resistance to moisture and cleaning agents. All straps must have a 20mm lug width.

The strap is changed using a dedicated spring bar tool to remove the elastic pins (spring bars) that secure the strap to the case lugs. Position the tool beneath the lug, apply gentle pressure to compress the pin, then withdraw the strap. Repeat on the other side. To install the new strap, insert the spring bars into the strap holes, then secure to the lugs by applying pressure until you hear the click. If uncertain, this service can be performed at a specialist watchmaker.

Yes, aftermarket straps are compatible with the Carrera CAR2A1J.FC6400, provided they have a 20mm lug width. Artisanal straps from suppliers such as Milano Straps offer superior quality and customisation compared to OEM straps, with material options (alligator, calf, vegetable tanning, shell cordovan) and finishes not found in the official TAG Heuer catalogue. Always verify that the strap has been manufactured for the correct lug width.

A high-quality leather strap, such as alligator or calf, has an average lifespan of 3-5 years with daily wear, provided it is properly maintained. Vegetable-tanned leather ages elegantly, developing a desirable patina. Factors such as humidity, perspiration and sun exposure accelerate wear. To extend lifespan, avoid water immersion (unless specifically waterproof), clean periodically with a damp cloth and occasionally apply a protective balm. Rubber or silicone straps have a longer lifespan (5-7 years) and require minimal maintenance.
