GTR Mini — Frequently Asked Questions
Will the Amazfit GTR Mini fit my wrist?
The Amazfit GTR Mini looks balanced on flat wrist widths of roughly 45–61mm (about 12.0–16.3cm circumference). Drag the slider above to check it against your own measurement.
What size band does the Amazfit GTR Mini take?
20mm. Any 20mm strap fits, so you are not limited to Amazfit's own bands — look for a quick-release fitting if you want to swap without tools.
How long does the Amazfit GTR Mini battery last?
Between 25 hours and 720 hours per charge, depending on the power mode. Amazfit rates Battery Saver at 720 hours and GPS at 25 hours; the chart above lists all 4 modes.
Is the Amazfit GTR Mini thick for a 43mm watch?
At 9.25mm, thinner than 99% of 43mm watches, so it slides under a cuff more easily than most of its size. Thickness, not case width, is what decides whether a watch catches on a shirt cuff.
What other watches are the same size as the Amazfit GTR Mini?
Garmin Bounce 2, OnePlus Watch 3 43mm, Oppo Watch X2 Mini, Omega Speedmaster Moonphase Stainless Steel / Black Meteorite / Bracelet all sit within half a millimetre of the Amazfit GTR Mini's 42.8mm case, so they cover the same amount of wrist.
