Strap for Grand Carrera Calibre 17 RS2 43 PVD / Black / Rubber

The lug width of the TAG Heuer Grand Carrera CAV518B.FT6016 is precisely 20mm. This specification is crucial for purchasing a compatible strap. To verify it yourself, measure the space between the two case lugs using a digital calliper or gauge: the distance between the centre of one bar and the other must be 20mm.

The ideal strap depends on your lifestyle. For formal wear: black alligator or vegetable-tanned calf leather in brown tones. For sports use: vulcanised rubber in anthracite or heavyweight canvas NATO strap. For versatility: Hermès calf with natural patina that develops over time. The 43mm case requires a proportionate strap: the 20mm lug width allows straps that do not appear undersized.

Position the watch on a soft surface with the caseback facing upwards. Locate the metal spring bars that connect the strap to the case lugs, inserted in small holes on both sides. Use an appropriate tool (spring bar tool) to compress the internal spring and slide it out of the hole. Repeat for the other side. Insert the new strap by clicking the spring bars into the appropriate slots. If you are not experienced, strap replacement is always recommended through a qualified watchmaker.

Yes, provided the strap is specifically manufactured for a 20mm lug width. However, it is essential to verify that the strap has a 20mm width at the attachment points, not only in overall width. High-quality straps produced by specialised manufacturers maintain the same aesthetics as the case and guarantee construction precision equivalent to the original.

A quality leather strap (alligator, calf, shell cordovan) has an estimated lifespan of 3-5 years with moderate daily use, assuming rotation with other straps. Durability depends on humidity, frequency of wear, sun exposure, and maintenance. Vegetable-tanned leather tends to develop a patina that improves over time. Rubber straps typically last 2-3 years before replacement is necessary. A specialised atelier can restore or replace worn sections without compromising the entire structure.
