OnePlus Watch 4

OnePlus Watch 4 accessories — screen films and 22 mm straps

The OnePlus Watch 4 launched in April 2026 — 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. As a new model, the accessory range at homescreen.pl is still building — currently a Bizon HydroFlex screen film is available, with more products arriving regularly.

Bizon Watch Film HydroFlex screen film

The Bizon HydroFlex hydrogel film (25 PLN, set of 3) 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. Three films in the set last for many months — simply replace 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.

What to expect in the coming weeks?

The Watch 4 is a fresh launch and the homescreen.pl range grows every week. Planned additions include hybrid glass, protective cases for the titanium body and replacement chargers. If you are looking for accessories for older OnePlus models, head to the OnePlus Watch 3 category (26 products) or OnePlus Watch Lite (8 products).

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. Cases will appear in the range in the coming weeks.

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.
