- Between 40 hours and 12 days per charge depending on the power mode — smartwatch at best, gps at worst.

- 48g on the wrist. Lighter than 82% of the 47mm watches we have weights for.
- 1.39 inches OLED/AMOLED display, always-on capable.
- Takes 22mm bands, so third-party straps fit without an adapter.
Does the GTR fit your wrist?
Drag the slider to your wrist width and see the GTR overlaid at true scale. Lug-to-lug — not case diameter — decides whether a watch overhangs your wrist.

GTR — Frequently Asked Questions
Will the Amazfit GTR fit my wrist?
The Amazfit GTR looks balanced on flat wrist widths of roughly 50–67mm (about 13.4–17.9cm circumference). Drag the slider above to check it against your own measurement.
What size band does the Amazfit GTR take?
22mm. Any 22mm 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 battery last?
Between 40 hours and 12 days per charge, depending on the power mode. Amazfit rates Smartwatch at 12 days and GPS at 40 hours; the chart above lists all 2 modes.
Is the Amazfit GTR thick for a 47mm watch?
At 10.75mm, thinner than 99% of 47mm 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?
Oppo Watch X3, Xiaomi Watch 5, CMF Watch 3 Pro, Garmin Forerunner® 570 - 47mm all sit within half a millimetre of the Amazfit GTR's 47.2mm case, so they cover the same amount of wrist.
