The lifespan of a leather strap depends on the material and frequency of use. A vegetable-tanned calfskin strap, with proper care, typically lasts 2–4 years with daily wear. An alligator strap, owing to the natural density of its scales, can last between 5 and 8 years. Regular exposure to water, perspiration, and UV light accelerates deterioration; rotating between straps and applying a leather conditioner periodically is strongly advised.
