The longevity of a leather strap depends on the material, care and frequency of use. A quality vegetable-tanned alligator strap, properly maintained with neutral wax and kept away from moisture, can last between 3 and 5 years with daily wear. Shell cordovan is notably more resilient and develops a distinguished patina over time. Calf leather straps generally have a shorter lifespan but offer excellent value when used in rotation.
