Oppo, a name synonymous with cutting-edge smartphones, has also carved out a significant niche in the smartwatch market. Their past innovations, particularly the Oppo Watch X2, have showcased class-leading technology that pushes the boundaries of what’s possible in a wearable device. Now, whispers of its successor, the rumored Oppo Watch X3, are painting a picture of a device that could set a new standard for the industry and potentially challenge even the most established players, like Google’s Pixel Watch 4. Given Oppo’s close relationship with OnePlus, there’s a strong possibility that this new flagship wearable will eventually be rebranded for a global audience, making it the highly anticipated OnePlus Watch 4.
Next-Generation Performance and Enduring Power
The heart of the rumored Oppo Watch X3, which could be the OnePlus Watch 4, is its potential to combine a powerful main processor with an incredibly efficient co-processor. Leaks suggest the device will feature the same satellite-capable Snapdragon W5 Gen 2 Plus SoC found in the Pixel Watch 4. However, what could give the Oppo wearable a significant edge is the return of the BES2800 co-processor. This proprietary chip was a key feature in the Oppo Watch X2, helping it achieve an impressive battery life of up to 120 hours on a single charge. This would be a stark contrast to the Pixel Watch 4’s expected 30-hour battery life, positioning the Oppo Watch X3 as a clear winner in the endurance race.
Enhanced Features and Health Monitoring
Beyond its processing power and battery longevity, the Oppo Watch X3 is said to bring a suite of features that enhance user experience and health tracking. One notable addition is a rotating crown, a feature missing from the Pixel Watch 4. This could provide a more intuitive and tactile way to navigate the watch’s interface. Furthermore, the device is expected to reintroduce an ECG (electrocardiogram) sensor, allowing users to monitor their heart’s electrical activity—a feature seen in some of its predecessors, albeit in China-only versions. The potential for “all-day health monitoring” also suggests a comprehensive approach to wellness. While current leaks don’t mention dedicated stress or skin temperature sensors, the combination of a rotating crown and ECG functionality makes the Oppo Watch X3 a compelling option for those who prioritize advanced health features.
A Potential Partnership with a New Flagship Phone
The timing of the Oppo Watch X3’s launch is also a subject of speculation. Following the February 2025 debut of its predecessor, a respected leaker, Digital Chat Station, suggests the new smartwatch will launch alongside a new smartphone, tablet, and audio accessories. This points to a potential unveiling at the “Find X9 Ultra” event, which is anticipated to take place early next year. This integrated release strategy would align the new smartwatch with Oppo’s premium flagship smartphone lineup, ensuring a synchronized and powerful market entry. With its combination of a powerful processor, exceptional battery life, and enhanced health features, the Oppo Watch X3 (or OnePlus Watch 4) could truly be a game-changer in the wearable technology landscape.
