The Watch Lite in short
The figures that decide whether this watch suits you, pulled out of the full specification sheet further down.
- Rated for 10 days of use per charge.
- Water rated to 50 m.
- 35g on the wrist. Lighter than 99% of the 45mm watches we have weights for.
- 1.46 inches OLED/AMOLED display, always-on capable.
- Takes 22mm bands, so third-party straps fit without an adapter.
Does the Watch Lite fit your wrist?
Drag the slider to your wrist width and see the Watch Lite 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
45mm 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 45mm, 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.

Is the OnePlus Watch Lite thick for a 45mm watch?
At 8.9mm, thinner than 100% of 45mm 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 OnePlus Watch Lite?
Garmin D2 Air X15, Oppo Watch S, Google Pixel Watch 4 - 45mm, Tissot T-Race Chronograph PVD / Black / Rubber all sit within half a millimetre of the OnePlus Watch Lite's 45mm case, so they cover the same amount of wrist.
