Which one fits you
On wrists narrower than about 59mm, the Amazfit GTR 2 is the safer pick — it stays proportionate down to roughly 49mm, where the Amazfit Ares starts to hang over the edge. Above 59mm both sit cleanly, and the Amazfit Ares gives you more presence.
The Amazfit Ares and Amazfit GTR 2 share a near-identical 46.5mm case, so wrist presence comes down to thickness, lug-to-lug and weight.
The Amazfit GTR 2 is the slimmer of the two (10.7mm vs 14mm), so it slides under a cuff more easily.
On the wrist the Amazfit GTR 2 feels lighter (39g vs 48g, case only).
The Amazfit Ares is middle-of-the-pack for thickness among the 149 47mm watches in the database.
Among the 158 46mm watches we hold thickness for, the Amazfit GTR 2 is thinner than 93%, so it wears flatter than its width suggests.
