I decided to wait a while on the new watch. I'm still happy with my current Apple Watch. While the GPS feature is cool, not sure it's something I need at the moment. Most of my running is on a treadmill
Stainless steel is stronger than aluminum but the surface scratches easier than the anodized finish on the aluminum Apple Watches. The black finished stainless steel Apple Watch models have a very durable finish that is almost impossible to scratch, but any deep scratches that do penetrate the finish are very visible.
