I am going for the Sport the first gen being i am in the gym 6 days a week. So thats what i intend to use it for, Sport. And running around on the weekends. Man the thought to be able to leave my iPhone 6 plus in my gym bag is a dream lol. Now my idea is to possibly get a band to dress it up once and a while after i see the 3rd party bands come out. I dunno i already have some Heavy Hitter diving and aviation watches some 50mm plus for when i dress up. But for the possible 2nd gen get the more premium and still use the "sport" first gen for gym and everyday wear.
