Strap for Grand Carrera Calibre 17 RS 43 Stainless Steel - Titanium / Black / Bracelet

The lug width of the TAG Heuer Grand Carrera CAV511C.BA0904 is 22 mm, measured between the centres of the two holes intended for the spring bar pins. This dimension is specific to the model and is essential to ensure correct strap compatibility with the 43 mm case.

The best strap depends on intended use. For formal-sporting wear, we recommend alligator with vegetable tanning (Testa di Moro) or sun-aged calf leather. For a contemporary alternative, rubber or natural rubber straps with chevron texture offer grip and stability. On milanostraps.it you will find options developed specifically for the visual balance of this chronograph.

Strap replacement requires a spring bar tool (thin metal lever). Insert the tool into the small notch on the side of the spring bar to compress it, then remove the pin from its seat. Repeat on the other side. Insert the new strap by aligning the holes with the pins and press until it clicks into place. If you prefer, the Casati Milano atelier offers a fitting service in-house with material consultation.

Yes, it is possible to mount quality aftermarket straps with 22 mm lug width. TAG Heuer, like most Swiss manufacturers, does not apply patents that restrict this practice. The straps available on milanostraps.it are developed following the exact parameters of the CAV511C.BA0904 case, ensuring mechanical and aesthetic compatibility without compromise.

The lifespan of a leather strap varies depending on material, tanning and intensity of use. A high-quality vegetable-tanned leather (such as the Testa di Moro used on milanostraps.it) resists an average of 3–5 years with daily wear. Genuine alligator, being more durable, can last 5–7 years. Rubber or natural rubber straps easily reach 7–10 years. The Casati Milano atelier guarantees 18 months on their made-to-measure straps, with the possibility of regenerating aged leather.
