Bertucci® DuraForm™ leather bands have been carefully designed to offer outstanding durability and comfort. The DuraForm™ band will quickly custom form to your wrist – eliminating the watch rolling outward to ensure a perfect ergonomic Active Comfort™ fit to your wrist. Manufactured from the finest materials... using the legendary #1 ranked Horween® leather tannery of Chicago, and matte finished solid stainless steel buckle and dual loops. The combination tanned leather is designed to offer excellent durability, comfort and beauty. The leather is hand tanned by craftsman using century old techniques to create a vegetable or bark tanned leather that is then hot stuffed with natural oils... resulting in a matte slightly waxy pull up finish... that naturally distresses and discolors to create a unique patina over the years. One size fits all. Three year warranty.
