The lifespan of a leather strap depends on the quality of the material, the tanning method used, and daily wear conditions. A high-quality alligator or shell cordovan strap with vegetable tanning can last between 3 and 7 years with proper care. Standard calf leather typically requires more frequent replacement, generally within 2 to 3 years under intensive use. Avoiding prolonged contact with water and perspiration significantly extends the strap's service life.
