Hmm, I should post pictures of my (fully working) replica of Edward Elric's pocket watch from Fullmetal Alchemist here.
Then don't get a leather watch band or metal watch band. Get a rubber one, like I have (I need one, since my skin tends to get allergic reactions to the other two types of armbands). They're water proof (obviously) and don't get soggy, and they're much more durable and don't flake or (easily anyway) tear. They're also not loose or jingly at all, are still light, and are comfortable.
