Strap for GrandeVitesse Chronograph Black Rubber

The lug width is precisely 20 millimetres. This dimension is model-specific and admits no variation: straps of 18mm or 22mm are not compatible. Measure between the inner margins of the two lug holes on the case.

This depends on intended use and aesthetic preference. Alligator in vegetable tanning is the most historically authentic choice: it offers pronounced texture and develops a caramel patina over time. Chromexcel calfskin represents a balance between elegance and versatility, with rich ageing characteristics. Shell cordovan guarantees structural rigidity and intrinsic brilliance. For demanding use, technical NATO textile or butadiene rubber preserves the original sporting spirit.

Remove the watch from your wrist. On each side of the case, at the lug attachment, you will find a small spring bar. Using a dedicated spring bar tool, push the bar inward to disengage the end, then extract the old strap. Insert the new strap by aligning its holes to the case lugs and reinsert the spring bar until you feel the locking click.

Yes, provided it is manufactured with a 20mm lug width. Many generic aftermarket straps are produced in 18mm or 22mm and are unsuitable. Bespoke artisanal straps guarantee mechanical compatibility and superior construction quality compared to universal mass-produced pieces.

A quality strap in full-grain leather (alligator, calfskin, cordovan) typically lasts between 4 and 7 years with moderate daily wear. Ageing is natural: the leather darkens, develops patina and becomes softer. Artisanal warranty covers construction defects and premature wear, but not the natural aesthetic deterioration. Factors such as humidity, sun exposure and perspiration accelerate the process.
