The lifespan of a leather strap depends on hide quality, frequency of wear, and exposure to perspiration and moisture. A quality vegetable-tanned calf leather strap worn daily under moderate conditions typically lasts 18–36 months. Alligator leather, owing to its scale structure, tends to offer greater longevity. Avoiding water immersion significantly extends strap life.
