What we like about Oneplus Watch 3

  • Exceptional battery life, reaching up to 5 days in Smart Mode and 16 days in Power Saver Mode.
  • High-quality premium design featuring a titanium bezel and durable sapphire crystal glass.
  • Extremely bright 1.5-inch AMOLED display with a peak brightness of 2200 nits for excellent outdoor visibility.
  • Addition of a functional rotating crown for intuitive and tactile menu navigation.
  • Fast charging capabilities, providing a full day of use from just a 10-minute charge.
  • Accurate dual-frequency GPS that locks on quickly and performs well during outdoor runs.

What we don't like about Oneplus Watch 3

  • Large and bulky 46mm chassis (81g with strap) that can feel heavy or oversized on smaller wrists.
  • Lack of cellular (LTE) connectivity, requiring a paired smartphone for most smart features.
  • Advanced health features like ECG are region-locked and unavailable in several major markets like the US and UK at launch.
  • Inconsistent heart rate tracking during high-intensity interval training (HIIT) compared to chest straps.
  • No compatibility with iOS devices, limiting its use strictly to Android users.
  • Reported issues with water resistance and swimming durability despite the IP68 and 5ATM ratings.

Verdict

The OnePlus Watch 3 features a 1.5-inch LTPO AMOLED display with 2,200 nits of peak brightness and a durable titanium alloy bezel. It is powered by a dual-engine architecture comprising the Snapdragon W5 performance chip and the BES2800 efficiency chipset, paired with 2GB of RAM and 32GB of storage. Running Wear OS 5, it introduces a functional rotating crown, dual-frequency GPS, and a '60-second Health Check-In' that monitors heart rate, SpO2, and vascular age. Main pros include a class-leading battery life of up to 5 days in smart mode (16 days in power saver), military-grade durability (MIL-STD-810H), and exceptionally fast charging (a full day of use in 10 minutes). Primary cons include a bulky design that may overwhelm smaller wrists, the absence of an LTE version, and limited deep fitness analytics compared to dedicated sports trackers.
