I must admit, I find cases, be they for watches, phones etc, just a means of keeping the device pristine for the next owner. One buys a beautiful phone/watch or whatever and immediately put it in a protective cover and don't get the benefit of the beauty of it. I don't really like the fact that I would be looking after it for the next owner. I buy it for me.
Edit; I do understand the need or desire to protect the device for specific activities that may damage it, such as the weight lifting bumper described by the gentleman above, that looks good.
Having said all the above, there is nothing wrong with someone wanting to keep their device that they spent good money on in a pristine condition. My comment wasn't a criticism, just how I see it and accept that the only right way, is that of the owner.
