Hi guys, So, the watch launched on April 24, 2015, which is almost a year now and I have the question of how are the materials doing? Specifically; the white sport band, is is dirty? broken? Does the SS version show scuffs and scratches? Does the black aluminium ones show major scratches like the iPhone 5? I am thinking on buying the second generation in September (?) but wanna now how are the materials holding out after a year of use. Thanks!
