Strap for Souveraine Chronomètre à Résonance 40 Red Gold / Pink

The lug width of the Souveraine 1499.3 CAR 40 RG PI is 20 mm, measured from the inside of the lugs. This width accommodates standard 20 mm leather straps and ensures compatibility with most artisanal strap manufacturers offering bespoke solutions.

For the red gold Souveraine, alligator in dark cacao, shell cordovan in deep bordeaux, or vegetable-tanned calf in medium brown are recommended. These materials establish visual harmony with the gold, developing complementary patinas over time that enhance the depth of the metal.

Strap replacement is accomplished by removing the spring bars connecting the case lugs to the strap. Using a dedicated tool, compress the internal spring, extract the bar, insert the new strap, and reposition the bar. Precision is essential to avoid scratching the case.

Yes, quality aftermarket straps with 20 mm lug width are fully compatible. Verify the tolerance of the leather passage (approximately 0.5 mm per side) and select manufacturers guaranteeing dimensional precision and noble materials, given the horological significance of this timepiece.

A quality leather strap, with regular use, maintains functional and aesthetic integrity for 3–5 years. As red gold develops patina, vegetable-tanned leather and shell cordovan acquire character with age. Longevity depends on usage frequency, climate, and material care.
