Strap for Carrera Calibre 1887 43 Stainless Steel / Space X / Calf

The lug width of the TAG Heuer Carrera CAR2015.FC6321 is 20mm. This measurement refers to the distance between the two spring bars located inside the case, to which the strap is attached. It is essential to measure this distance with a ruler positioned on the inner face of the case to ensure correct compatibility with any aftermarket strap.

For the Carrera CAR2015.FC6321, an alligator strap with vegetable tanning represents the optimal choice due to its regular grain and natural patina that enhance the model's sporting heritage. Shell cordovan is the premium alternative for those seeking deep colours and superior durability. For daily wear, satinised calf offers formal versatility, whilst for sporting activities a cotton NATO or FKM rubber strap provides practicality without aesthetic compromise.

To change the strap on the Carrera CAR2015.FC6321, position the watch with the lug facing upwards. Use a dedicated tool (spring bar tool) to gently compress the internal elastic pin from one side, then remove the old strap. Repeat the operation from the other side. Insert the new 20mm strap, aligning it correctly in both slots, and release the pin. Verify that the strap is securely fastened before wearing the watch.

Yes, any strap with a 20mm lug width is compatible with the TAG Heuer Carrera CAR2015.FC6321. Quality aftermarket straps, such as those made from alligator, shell cordovan or calf, are mounted identically to original straps. We recommend relying on manufacturers who guarantee consistent thickness and finishing appropriate to the stainless steel case of the model.

The durability of a leather strap depends on the material and usage. A quality artisanal alligator or shell cordovan strap with vegetable tanning typically lasts 3-5 years of daily wear before requiring replacement. Calf has similar longevity, approximately 2-4 years. This period increases if the strap is used in rotation with other models. Regular maintenance (drying after humidity exposure, avoiding prolonged soaking) significantly extends service life.
