Hi everyone. Today I received a space gray and a space black apple watch series 2. I just couldn't decide so I ordered both. I really like both of them, but am having a hard time justifying the higher cost of the space black. I wanted the space black because I am concerned about the space gray getting a lot of scratches on the screen. That will drive me crazy. I also plan to keep this for a long time. Which one should I return?????
