Our Seat Belt NATO Straps are comfortable, durable, waterproof, and washable. They are made from the strongest, softest nylon weave we could find, and finished with heavy duty stainless steel hardware. They have a handsome, luxurious sheen that will complement fine timepieces and beater military watches alike. Once you've removed your old band, you can swap them out quickly and easily, with no tools required. Length is one-size-fits-all and any excess length can be folded back and tucked away. If you have any issues with your strap whatsoever, we offer a full money back guarantee.
