You're buying this because it's cheaper and want to know the differences between the versions.

USA perspective: This is the actual Samsung watch, it functions exactly like the US version. There are only minor differences and a few application limits depending on your location.
It's brand new and sealed in the original packaging.
First the units are set to Metric. Temperature is tracked in Celsius (which wouldn't kill you to learn) but it's trivial to set the notifications to your preference.
Second this unit doesn't indicate that it comes with the default warranty.
That's basically it. It functions very well, no lag, water resist is great (I shower and swim with it on) and it's quick to charge. It functions via bluetooth and can connect to wi-fi.
