OnePlus Watch 3 Bands (46mm & 43mm)

OnePlus Watch 3 Bands — What Fits

OnePlus Watch 3 bands on this page fit both case sizes released in 2025: the 46mm model, which takes 22mm bands, and the smaller 43mm model, which takes 18mm bands. Both use a standard quick-release spring bar at the lugs, so a compatible band snaps on without an adapter or specialty tools.

The two Watch 3 sizes look similar side by side, so it's worth double-checking which one you own — the case size is printed in the watch settings and on the original packaging. Ordering the wrong width is the single most common mistake with this watch.

Bands for Every Use Case

The 22mm Watch 3 46mm takes the full 22mm quick-release range: silicone sport, nylon and braided loops, magnetic milanese and genuine leather. The 18mm Watch 3 43mm takes the Rovan magnetic silicone sport band, the Jelli silicone sport band and the Tressa magnetic braided loop.

Sport and Everyday Training

For the 46mm case, the Vornis silicone sport band is built for running, gym sessions and anything sweaty — it rinses clean in seconds (see our full silicone watch bands range). The Véllo and Bravik nylon loops are lighter, breathable alternatives for warm-weather workouts.

Office and Dressier Looks

The Solin magnetic milanese swaps the sporty look for a polished mesh with a magnetic closure, good for meetings or evenings out. The Mavric braided loop achieves a similar dress-up effect with a woven texture and no visible buckle.

Sleep Tracking and All-Day Comfort

The Rovan magnetic silicone sport band is the pick for overnight wear — it closes with a magnet instead of a hard buckle, so there’s nothing to dig into your wrist, and it’s made for the 43mm case. It also comes in 22mm for the 46mm case, where the Voren nylon loop is a similarly soft, low-profile option for all-day comfort.

How to Swap Your OnePlus Watch 3 Bands

Before ordering, confirm your case size — this is the step people skip, and 46mm and 43mm bands are not interchangeable on the Watch 3.

• Lay the watch face-down and find the small lever on the underside of the band, right where it meets the case.
• Push the lever toward the center of the case to retract the spring bar and release the old band.
• Line up the new band's spring bar with the same lug holes and press until it clicks into place.
• Tug gently on both sides to confirm it's seated — the whole swap takes well under a minute.

Caring for Your Bands

Rinse the Vornis silicone band under water with a little mild soap and let it dry fully before wearing it again. The Véllo, Bravik and Voren nylon loop bands can be hand-washed and air-dried — avoid the tumble dryer, which can shrink the weave.

Wipe the Solin magnetic milanese and the Rovan magnetic silicone sport band with a soft, slightly damp cloth rather than soaking them, so the magnets and clasp keep working smoothly.

Which Watches Don't Fit

There's no compatibility issue with the Watch 3 itself — both sizes use standard quick-release bands. The trap is width, not fit: 22mm bands do not fit the 43mm case, and 18mm bands do not fit the 46mm case. If you're shopping for a different OnePlus model instead, the Watch 2, Watch 2R and original Watch (2021) are all 22mm — see the OnePlus Watch 2 Bands page for those.
