The GTS - global version in short
The figures that decide whether this watch suits you, pulled out of the full specification sheet further down.
- Between 25 hours and 1104 hours per charge depending on the power mode — battery saver at best, gps at worst.
- Water rated to 50 m.
- 24.8g on the wrist. Lighter than 89% of the 36mm watches we have weights for.
- 1.65 inches OLED/AMOLED display, always-on capable.
- Takes 20mm bands, so third-party straps fit without an adapter.
Does the GTS - global version fit your wrist?
Drag the slider to your wrist width and see the GTS - global version overlaid at true scale. Lug-to-lug — not case diameter — decides whether a watch overhangs your wrist.
Watch Fit Tool
For sports watches, lug-to-lug (L2L) is what matters most — it decides whether a watch overhangs your wrist. Bulky is fine; overhang is not.
Measure at the point where you wear your watch — typically just below the wrist bone.
Flat width — lay your arm on a table, palm facing up, and measure straight across the top of your wrist with a ruler. Bone to bone; do not follow the curve down the sides.
Around — wrap a tape measure snugly round the wrist. No tape? Wrap a strip of paper, mark the overlap and hold the strip against a ruler.
Width ≠ circumference. They are different numbers — around 170mm is about 64mm across — so set the toggle to whichever one you actually measured before you type it in.

Case 43.3mm · Lug-to-lug 43.3mm · Thickness 9.4mm · 25g
Balanced Fit
43.3mm on a 55mm wrist
Comfortably inside the edges of your wrist, and it seats and sits low enough to wear without thinking about it.
On a 55mm wrist the sweet spot is 47–53mm lug to lug. This one is 43.3mm, so you could go bigger.
Measure where you wear it, just below the wrist bone. Either of these works — the tool converts between them.
- 1. Flat width — arm flat on a table, palm up. Measure straight across the top of the wrist, bone to bone, ignoring the curve down the sides.
- 2. Around — a tape, or a strip of paper marked and held against a ruler, snug the whole way round.
Leather: Attaches at the lugs, so the case back rests on your skin. Thins and softens with wear. Typical figures, not this model’s own.

What size band does the Amazfit GTS - global version 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 GTS - global version battery last?
Between 25 hours and 1104 hours per charge, depending on the power mode. Amazfit rates Battery Saver at 1104 hours and GPS at 25 hours; the chart above lists all 3 modes.

Is the Amazfit GTS - global version thick for a 36mm watch?
At 9.4mm, middle of the pack for thickness at this width. 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 GTS - global version?
Zenith Defy Skyline 36 Stainless Steel - Diamond / Silver, Apple Watch Series 11 - GPS + Cellular · Aluminium · 42mm, TAG Heuer Aquaracer Professional 300 36 Stainless Steel / Blue Gradient - Diamond / Rubber, Tissot Seastar 1000 36 Quartz Stainless Steel - Rose Gold / Black / Bracelet all sit within half a millimetre of the Amazfit GTS - global version's 36.25mm case, so they cover the same amount of wrist.
What is the lug-to-lug of the Amazfit GTS - global version?
43.25mm, against a 36.25mm case width. Lug-to-lug is the measurement that decides overhang: if it exceeds the flat width of your wrist, the lugs sit past the edge no matter how modest the case diameter looks.
