Amazfit GTS Straps — What Fits
Whether you're searching for an Amazfit GTS 4 strap or Amazfit GTS replacement straps for an original GTS, every model in the line — GTS, GTS 2, 2 Mini, 2e, 3, 4 and 4 Mini — shares the same 20mm quick-release lug, so one strap size fits the whole family.
The GTS is Amazfit's square-faced sibling to the round GTR, aimed at a slimmer profile on the wrist, but the two lines don't share a width — GTR runs 22mm or 20mm depending on case size, while every GTS is 20mm regardless of generation.
Changing an Amazfit GTS strap needs no tools: push the lever on the back of the strap, slide the old pin out of the lug, and press the new strap's pin in until it clicks.
Because every GTS model listed above uses the same width, this is one of the simpler Amazfit families to shop for — there's no case-size chart to check first, unlike the GTR or Cheetah lines. That consistency also means a secondhand or hand-me-down GTS keeps whatever strap width you already own.
Why the Right Strap Matters on a GTS
Because the GTS runs continuous heart-rate and sleep tracking, a strap that's too stiff or traps sweat can affect both comfort and sensor readings. Rotating between a sport strap for the day and a lighter loop for sleep keeps the watch comfortable around the clock without ever touching the watch head.
A strap that's genuinely comfortable overnight is often the difference between a full week of sleep data and several skipped nights. The same logic applies during the day — a snug, breathable strap is less likely to be pulled off mid-workout.
Because these are third-party compatible straps rather than Amazfit's own single boxed strap, you get far more colors and materials to pick from than the one option in the box, without paying accessory-store prices for each additional style.
Strap Styles for the GTS
All six of our quick-release styles come in 20mm, so every GTS generation has the full range to choose from.
- Vornis silicone sport for training and swimming, since it sheds water instantly and rinses odor-free.
- Véllo and Voren nylon loops for lightweight all-day and overnight wear, especially if silicone runs too warm for you.
- Mavric braided loop for a casual everyday look with a bit more texture than plain silicone.
- Solin magnetic milanese for the office, where the metallic finish reads more formal.
- Rovan magnetic loop for fast on-and-off wear on busy days.
Sizing and Swapping Your GTS Strap
Because every GTS generation uses the same 20mm width, you don't need to double-check case size the way GTR or Cheetah owners do — any strap in this collection fits any GTS. Not to be confused with the Amazfit GTR line, which is a different case shape — see Amazfit GTR Straps if that's your model instead.
If the spring-bar lever feels stiff the first time, that's normal on a new strap and tends to ease after the first couple of swaps.
- Lay the GTS face-down and find the spring-bar lever on the underside of the strap.
- Push the lever in and slide that end off the lug.
- Repeat on the other side to remove the strap.
- Press the new strap's spring bar into the lugs until it clicks on both sides.
- Tug gently to confirm the strap is fully seated before wearing it.
Caring for Your GTS Strap
Treat each material a little differently rather than rinsing everything the same way.
- Silicone — rinse after workouts with mild soap and let it air dry fully before the next wear; don't leave it balled up while damp.
- Nylon — machine-wash cold inside a mesh laundry bag, then air dry rather than using a dryer, which can warp the weave.
- Magnetic or milanese — wipe with a damp cloth rather than soaking, and dry the clasp before reattaching so moisture doesn't sit in the closure.
Which Watches Don't Fit These Straps
These are 20mm GTS straps, so several other Amazfit models — some with easily confused names — need something different. It's worth checking even if you're confident in your model, since a few of these mix-ups come up often:
- Amazfit T-Rex 1, T-Rex Pro and T-Rex 2 use proprietary connectors — standard straps, including these, do not fit. Only T-Rex 3 and T-Rex 3 Pro moved to the standard 22mm quick-release system.
- T-Rex Ultra uses screwed 22mm bars rather than quick release, and T-Rex Ultra 2 is 26mm — neither works with the quick-release straps sold here.
- Amazfit Verge and Verge Lite have straps built into the case, so they cannot take a replacement strap at all.
- Cheetah width depends on the exact model: round Cheetah, Cheetah Pro and Cheetah 2 Ultra are 22mm, but Cheetah Square and Cheetah 2 Pro are 20mm — the wrong width will not seat in the lugs.
- Active Edge does not appear on Amazfit's official compatibility chart, so we do not recommend standard straps for it.
Shop Amazfit GTS Straps with Confidence
Every style here ships fast and comes with easy returns, so trying a new color or material for your GTS is low risk. If you also own another Amazfit model, browse the full Amazfit watch straps lineup to find the right width for it too. Since every strap shares the same tool-free fitting, there's no downside to keeping a couple of styles in rotation.
