The lifespan of a leather strap depends on the material and usage. A quality vegetable-tanned calf strap, maintained regularly with a neutral leather conditioner, typically lasts 2–4 years of daily wear. Alligator, owing to the density of its skin fibre, generally lasts longer but is more sensitive to prolonged moisture exposure. Straps produced by Casati Milano for the Chronomat B01 42 carry an 18-month warranty against manufacturing defects.
