Actually got this to replace the metal band on my new AMW330-1AV. Both the AMW320 and the AMW330 come with a 22mm wide band so they are interchangeable. For all day wear, I prefer the resin band over the Stainless Steel type. So now I have the watch I liked and the band I prefer. Don't know about durability yet, but I do have the Stainless Steel band as a backup. Easy to swap out bands with a jewelers screwdriver and the right amount of caution. You just have to be sure you don't shoot the spring clip/pin across the room as you compress it.
