Before we knew the pricing, for me it was a choice between the Sport in space grey, or the SS with blue leather loop. Two things have changed. First, they've re-rendered the blue leather loop and now it really does look "bright" blue as they describe it. I don't like it. They've added a black one. Don't like that one, either. Second we now know there's £180 difference between the Sport with rubber strap and the SS with rubber strap. £180 for what? Different glass at the front (could I really tell the difference?) and different back (could I really tell the difference?). The Sport is lighter and the space grey carries no price premium. And I honestly don't like any of the straps for the SS. Oh, and there's no distracting shiny silver band around the screen. The whole thing's black and the screen just glows out of it. Lovely. Plus, I won't be too pissed off if the Apple Watch 2 comes out next year and is so much better. I will have spent £339 compared with £529. So Space Grey it is. 42mm. Two days late for my birthday Am I missing something here? What else does the SS have apart from what I regard as invisible cosmetic/psychological differences?
