Strap for Grand Carrera Calibre 36RS Caliper Chronograph PVD / Black / Alligator

The lug width of the TAG Heuer Grand Carrera CAV5117.FC6237 is 22 millimetres. This dimension is specific to the Grand Carrera models of this generation and is essential for ensuring a correct fit without excessive play. We measure the lug using a digital calliper from the inner right shoulder to the inner left shoulder to obtain the necessary precision.

The best strap depends on the intended use and personal preferences. For daily elegant wear, we recommend vegetable-tanned leather in cognac or dark brown tones with a coarse grain that enhances the sporting character. For those desiring longevity and evolving patina, natural alligator is the premium choice. For intensive use, a technical NATO or structured rubber entirely eliminates maintenance whilst preserving sporting authenticity.

Changing the strap requires the use of a specialised lug remover to avoid scratching the polished steel lugs. Position the watch with the lugs perpendicular to the work surface, carefully insert the remover into the articulation between lug and existing strap, and extract by pushing with constant pressure. The new strap should be inserted by aligning the hole perfectly with the lug before pushing until a noticeable lock engages.

Absolutely. The TAG Heuer Grand Carrera CAV5117.FC6237 uses standard 22mm lugs, compatible with any artisanal strap of that measurement. Using quality aftermarket straps – in vegetable-tanned leather, alligator, or shell cordovan – does not affect the warranty and allows seasonal rotations without excessive investment.

Durability depends on the type of leather and intensity of use. A quality vegetable-tanned leather, with minimal maintenance (protection from direct rain, occasional balm application), lasts 2-3 years with daily use before requiring regeneration. Alligator and shell cordovan, thanks to superior fibre density, can last 4-5 years or beyond. The important factor is to rotate straps to allow fibre drying and rest.
