OnePlus is making a serious push into premium smartwatch territory with its latest Watch 4. The company unveiled a device that trades the usual aluminum and plastic for titanium alloy construction, sapphire crystal glass, and software that’s ahead of early expectations.
This represents a clear shift in OnePlus’s wearable strategy. Where previous generations competed mainly on battery life and value, the Watch 4 targets users willing to pay more for materials that match flagship traditional watches. It’s a move that puts OnePlus in direct competition with Apple’s Ultra series and Samsung’s premium Galaxy Watch models.
The Watch 4 uses a full titanium alloy case with sapphire crystal protection and a fiberglass-reinforced back. The body measures 47.4 x 47.4 x 11.0 mm and weighs 43g without the strap, reaching 68g with it attached. OnePlus offers two versions: Midnight Titanium with a fluororubber strap and Evergreen Titanium with a mixed fluororubber strap.
Durability gets significant attention. The watch carries 5 ATM water resistance, IP68 and IP69 ratings, plus MIL-STD-810H military certification. This combination should handle everything from swimming to construction work, addressing a common complaint about fragile smartwatch builds.
The display stands out for outdoor use. OnePlus uses an LTPO OLED panel with 466 x 466 resolution and 310 PPI. Standard brightness hits 600 nits, rising to 1500 nits in bright conditions. The headline feature is peak brightness of 3000 nits during sports modes under direct sunlight.
That brightness figure matters for athletes training outdoors. Most smartwatches become difficult to read in bright sun, forcing users to shade the screen or move to darker areas to check metrics. A 3000-nit display should remain visible even during summer cycling or running sessions.
Hardware stays in flagship territory with Qualcomm’s Snapdragon W5 processor and BES 2800 co-processor, paired with 2GB RAM and 32GB storage. This combination has proven effective in other premium Wear OS devices for smooth performance and app switching.
Battery life targets one of Wear OS’s biggest weaknesses. OnePlus rates the Watch 4 at:
- Up to 16 days in power saver mode
- Five days in smart mode
- Three days under heavy use
Charging takes around 75 minutes with 7.5W support. These numbers position the Watch 4 well against typical Wear OS devices that often require daily charging.
Software brings a pleasant surprise. The watch runs OxygenOS Watch 8 with Wear OS 6.0, not the Wear OS 5 that earlier reports suggested. This gives buyers a more current software foundation and likely means longer update support.
Connectivity includes Bluetooth 5.2, dual-band L1 and L5 GPS, Wi-Fi on 2.4GHz and 5GHz bands, NFC, and Google Wallet support. The missing piece is eSIM support, which limits standalone functionality compared to cellular-enabled competitors.
Health tracking covers the expected basics: optical heart rate monitoring, blood oxygen measurement, wrist temperature tracking, sleep analysis, and OnePlus’s 60-second Wellness Overview. ECG support is included but depends on local regulatory approval.
Fitness features span over 100 sports modes with detailed metrics for running, skiing, tennis, badminton, and swimming. Advanced features include track running mode, aerobic training effect analysis, cardiopulmonary capacity measurement, and recovery time estimates.
The Watch 4 represents evolution rather than revolution for OnePlus wearables. The core experience remains familiar, but premium materials and improved durability should appeal to users who want smartwatch functionality in a package that feels more like traditional luxury timepieces. OnePlus hasn’t announced pricing yet, but the titanium construction and sapphire glass suggest a significant step up from previous generations.
This positioning makes sense as the smartwatch market matures. Early adopters focused on features and battery life, but mainstream buyers increasingly want devices that look and feel premium enough for professional settings. The Watch 4’s materials and build quality address that demand while maintaining the battery advantages that made previous OnePlus watches competitive.
