In addition to softening and molding to your wrist, leather watchbands naturally stretch and flex as they break in. As a result, you will likely move to a smaller hole after a few weeks of wear. Tuck excess length back under the keeper loops for maximum comfort.To maintain the color and keep your watchband looking new, use a damp rag or leather conditioner to spot clean. Avoid excess water, which can darken the band and cause color transfer. Lightly oil your NATO when it begins to feel dry to avoid cracking.
