Unlike the Style, on the Sport the antenna extends into the strap, which means it only fits proprietary, non-changeable, bands. These are rigidly angled inwards, but while I found this a little annoying on the Asus ZenWatch 3, I see its merits for heart rate tracking on the Sport and generally making the watch feel snug on the wrist while exercising.
The Garmin Vivomove sport smartwatch barely classifies as smart. Rather than focusing on features, it emphasizes the appearance and function of a traditional watch, with smart features sprinkled on top. The hardware of the Vivomove won’t impress those interested in the latest and greatest Android Wear or Apple Watch devices. It doesn’t display much data beyond movement and steps taken.
