OPPO Watch X3: Dual chip and multi-day battery in Wear OS

The OPPO Watch X3 is among the nominees for best wearable at the 2026 La Razón Technology and Consumer Awards, alongside the Google Pixel Watch 5 and the Samsung Galaxy Watch Ultra 2. The nomination confirms it competes in that category, but it does not prove it is the best watch nor validate its health measurements. The ceremony is scheduled for October 28, according to the list published on October 10.

The proposal that distinguishes the Watch X3 in available information is a dual-processor architecture and above-average battery life for some Wear OS watches, according to independent reviews. The practical question is not whether a nomination equals an award, but whether the watch's duration and features fit the intended use and the price available in the local market.

The technical sheet published by Xataka identifies a Snapdragon W5 Gen 1 and a BES2800BP co-processor. Analyses describe a division of tasks between the main chip and the low-power one; this architecture can help extend battery life when the watch alternates between full functions and less demanding operations. However, this is not enough to conclude that it has solved the power consumption of all Wear OS watches.

Xataka reports more than four days of use with daily workouts and active background sensors. Revista Gadget also describes a usual duration of over four days in its test scenario. Battery life is a conditioned experience dependent on settings, notifications, workouts, and screen use: it should not be read as a guaranteed figure for every user. OPPO advertises up to 16 days on its Spanish page, but that maximum figure does not equate to the result of use with all functions active.

Data published by Xataka describe a 1.5-inch LTPO AMOLED display with a resolution of 466 × 466 pixels. The analysis also specifies sapphire crystal and a weight of 43 grams without the strap. Revista Gadget identifies the case as TC4 titanium alloy and notes IP69 and 5 ATM resistance. These features help assess size and materials, but a resistance rating does not mean the watch is indestructible nor does it replace the manufacturer's usage conditions.

For outdoor readability, Xataka distinguishes several brightness levels: 600 nits as the usual maximum, 1,500 nits in sunlight, and up to 3,000 nits in a sports mode. It is advisable to maintain that distinction: the highest value is associated with specific use, not a constant display measurement. The combination of large size and 47.4 mm case also makes it advisable to consider the wrist fit before purchasing.

El Grupo Informático lists among health features an eight-channel optical heart rate sensor, ECG, hypertension risk measurement, blood oxygen, and skin temperature. This list describes available functions; it does not attest to clinical accuracy nor prove the watch can diagnose diseases. The included sources do not provide independent medical validation or comparative accuracy data against reference equipment.

The distinction matters especially for ECG and blood pressure: a watch alert or estimate may be useful for observing trends, but it should not replace a professional evaluation. Blood glucose measurement should not be attributed to the Watch X3: a La Sexta note mentions that function, but other provided materials do not offer sufficient corroboration, and the official page consulted limits itself to describing health tracking and improved sensors. If clinical measurement is the priority, one must check the applicable authorization and usage conditions in the country, data not established by available sources.

MovilZona cites a price of 379 euros for Spain; Amazon shows an offer of 319.99 euros in the consulted sheet, although that page does not provide a dated and complete availability observation here. These are distinct references and should not be confused: a store's price can change, while a review's price does not necessarily match the current price. Check seller, variant, and final price before making a decision.

Available research does not allow a reliable comparison with Apple Watch Series 12 or Galaxy Watch Ultra 2: verifiable sources for their specifications, prices, and battery life in specific models and markets are missing. Therefore, it is not responsible to present a table of differences or claim the OPPO is cheaper or superior in features. The nomination does confirm the three models appear in the same award category, but it does not make them equivalent or provide a comparative proof.

The Watch X3 deserves consideration if you seek a watch with Wear OS, a large screen, and multi-day battery life according to independent tests. The dual chip is a relevant argument for those who want to reduce charging frequency without giving up connected watch features; real duration depends on the usage pattern and should not be automatically extrapolated to all scenarios.

Before deciding, it is advisable to check three aspects: compatibility with the phone and apps used, case size and comfort, and local availability of health features. If the main purchase reason is to measure blood pressure or perform an ECG with medical value, the gathered information is not enough to recommend it for that purpose. The supported conclusion is more limited: it is a 2026 candidate with a dual-processor configuration and reviews reporting several days of battery, not a demonstration of medical accuracy or general superiority over rivals.
