The Gear Sport in short
The figures that decide whether this watch suits you, pulled out of the full specification sheet further down.
- Rated for 3 days of use per charge.
- Water rated to 50 m.
- 50g on the wrist. Heavier than 68% of the 43mm watches we have weights for.
- 1.2 inches OLED/AMOLED display, always-on capable.
- Takes 20mm bands, so third-party straps fit without an adapter.
Does the Gear Sport fit your wrist?
Drag the slider to your wrist width and see the Gear Sport 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.

Balanced Fit
44.6mm 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 44.6mm, 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.

Gear Sport — Frequently Asked Questions
Will the Samsung Gear Sport fit my wrist?
The Samsung Gear Sport looks balanced on flat wrist widths of roughly 47–64mm (about 12.6–17.1cm circumference). Drag the slider above to check it against your own measurement.
What size band does the Samsung Gear Sport take?
20mm. Any 20mm strap fits, so you are not limited to Samsung's own bands — look for a quick-release fitting if you want to swap without tools.
How long does the Samsung Gear Sport battery last?
Samsung rates it at 3 days per charge in everyday use.
How does the Samsung Gear Sport battery compare with other Samsung watches?
At 3 days in everyday use it ranks #4 of the 64 Samsung watches in our database — the top 6% of the range. The full ranking, including GPS and power-saving figures, is on our Samsung battery life comparison.
Is the Samsung Gear Sport thick for a 43mm watch?
At 11.6mm, thinner than 86% 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 Samsung Gear Sport?
Garmin Fenix 9 43mm, OnePlus Watch 3 43mm, Oppo Watch X2 Mini, Omega Speedmaster Moonphase Stainless Steel / Black Meteorite / Bracelet all sit within half a millimetre of the Samsung Gear Sport's 42.9mm case, so they cover the same amount of wrist.
What is the lug-to-lug of the Samsung Gear Sport?
44.6mm, against a 42.9mm 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.
