D2™ Mach 1 Pro
Which one fits you
On wrists narrower than about 54mm, the Amazfit Balance 2 is the safer pick — it stays proportionate down to roughly 50mm, where the Garmin D2™ Mach 1 Pro starts to hang over the edge. Above 54mm both sit cleanly, and the Garmin D2™ Mach 1 Pro gives you more presence.
The Garmin D2™ Mach 1 Pro wears larger than the Amazfit Balance 2 (51mm vs 47.4mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.
The Amazfit Balance 2 is the slimmer of the two (12.3mm vs 15mm), so it slides under a cuff more easily.
On the wrist the Amazfit Balance 2 feels lighter (43g vs 126g, case only).
Among the 83 47mm watches we hold thickness for, the Amazfit Balance 2 is thinner than 81%, so it wears flatter than its width suggests.
The Garmin D2™ Mach 1 Pro is middle-of-the-pack for thickness among the 48 51mm watches in the database.
