The lifespan of a leather strap on the Breitling Colt A1731311.BE90.182A depends on the material and frequency of use. A quality vegetable-tanned calfskin strap worn daily typically lasts 2–3 years before showing structural wear. Shell cordovan, owing to the density of its fibres, can last considerably longer. Frequent exposure to water shortens strap life significantly; for intensive use, rubber or NATO straps are recommended.
