Yes, the Amazfit GTR has a built-in GPS+GLONASS receiver, which can be used in some of the 12 exercise modes, in addition to the optical heart rate monitor. The watch is water resistant up to 5ATM, so you can take it for a swim (Huami advertises both pool and open water swimming).
In terms of smartwatch functionality, the GTR will display notifications, event reminders, incoming texts and calls (but there’s no loudspeaker). It will also show weather information, the music info from your phone and a compass.
The Amazfit GTR 42mm standard edition starts at CNY 800 ($120/€105) and comes with 20mm silicone straps in Black, Pink or White. There’s also a special edition with 60 cubic zirconia and a white leather strap. This watch weighs 25.5g without a strap.
The Amazfit GTR 47mm starts at CNY 1,000 ($145/€130) for the aluminum and stainless steel versions (which come with a 22mm brown leather strap). There’s also a titanium version (with a fluoro-rubber strap), which will set you back CNY 1,400 ($205/€170).
The titanium model is the lightest at 36g, the aluminum version is 40g and the steel one has some more heft to it at 48g.
