OnePlus Watch 4

Accessories for OnePlus Watch 4 — screen films and 22 mm straps

The OnePlus Watch 4 is the first OnePlus smartwatch with a titanium case, sapphire crystal and Wear OS 6.0 on the Snapdragon W5 Gen 1 chip. The round 1.5" LTPO AMOLED display (466x466 px, 3000 nits), 2 GB RAM, 32 GB storage and MIL-STD-810H certification make it one of the toughest watches running the full Google ecosystem.

Hydrogel screen film

Hydrogel film is a self-healing protective layer shaped for the round Watch 4 display. It guards the sapphire screen against scratches and scuffs without reducing touch sensitivity. It is worth replacing the film when it loses clarity.

22 mm straps — full quick-release compatibility

The OnePlus Watch 4 is great news for customisation fans: the watch uses standard 22 mm quick-release straps. No adapters or proprietary connectors needed. This means compatibility with straps from the OnePlus Watch 3, OnePlus Watch 2 / 2R and thousands of 22 mm straps on the market — silicone, nylon, leather, metal or fabric. At just 43 g case weight, a light nylon or silicone strap provides sporty comfort, while a metal bracelet adds elegance.

Frequently asked questions

Do straps from the OnePlus Watch 3 fit the Watch 4?

Yes. Both models use standard 22 mm quick-release straps. Any 22 mm strap — original OnePlus, third-party brand or universal — will be compatible with the Watch 4 without any modifications.

Does the titanium Watch 4 case need a protective cover?

Titanium is lighter and harder than steel, but not immune to micro-scratches. If you wear the watch daily and want to preserve the factory finish, a bumper case will protect the case sides.

What are the differences between the Watch 4 and Watch 3 for accessories?

22 mm straps are interchangeable. However, the Watch 4 case (47.4 x 47.4 x 11 mm, titanium) has different dimensions than the Watch 3, so cases and tempered glass are not cross-compatible. Screen films also differ in shape — both have a 1.5" AMOLED display, but with different edge curvatures. Accessories for the Watch 3 are available in a separate category.
