Holding up great, no grease marks or other marks...but we will see after I work out in the garden.
It's funny, I would hate to work at apple store the next few months, iphone users are so fussy and use cases. So the smallest mark can freak them out.
These are watches, SS watches all get scratches, and bands especially get marked up, all the bands will show some wear, it's all good
But I'm feeling these space grey models may really show the wear, so I might just stick with the regular sport version.
This is why I went for the white one in the end. Bad memories of my iPhone 5 looking like crap as the black coating slowly chipped away.
