I bought the original GT watch a while back but returned it as you can't export activities to other platforms (e.g Strava) which was important to me. I know its an old model but I imagine the same limitation applies. The screen was superb though.
I eventually went for the Garmin venu instead. Garmin watches are generally better for fitness tracking (if that's what you're into), but the screens on their entire range are rubbish apart from the venu.
It does have NFC but that doesn't interest me.
Yeah i did read about the Strava integration. However I think as long as I can still track my runs through the health app i am fine with that. At £95 I can always sell on and move on as and when I want to, but apart from a fitbit blaze which was terrible this will be my first decent smart watch.
