Got a chance to try both on today. The Sport and the SS look beautiful, but there are definitely different "feelings" given for both. The Sport (to me) definitely gives off a fitness band vibe. It's significantly lighter and the aluminum well, looks very sporty. As someone who wears a suit and tie everyday, it would be tough for me to wear this as a daily driver. Maybe with a different (leather or milanase) band it would give a different vibe, but the watch is just pretty light overall. I am current larger face watch wearer and the lightness of the sport just felt more a fitbit I used to wear with a screen The SS, to me felt heavier and more substantial. It feels more like a formal watch. If you dress up everyday, I feel like this would be a better choice and would feel like you were wearing any other kind of watch. On the other hand, this really would not feel right as an everyday "gym" watch. I personally went with the SS since it would be the type I would most likely wear everyday. To each their own, but just wanted to put that out there.
