The lifespan of a leather strap depends on leather quality, frequency of use, and exposure to perspiration and moisture. A quality vegetable-tanned calf strap worn regularly typically lasts between 18 and 36 months. Vegetable-tanned alligator, with its denser fibre structure, can exceed three years when treated with appropriate conditioners and kept away from water. Rotating between two or three straps considerably extends the life of each.
