Oppo Watch 4 Pro: Company confirms skin temperature sensor, ECG and performance improvements for new smartwatch

On the one hand, the Watch 4 Pro will retain its predecessor's Snapdragon W5 Gen 1 SoC. Typically, that would seem like an unusual decision, but Qualcomm has yet to replace the Snapdragon W5 Gen 1 platform. The 4 nm chipset remains best-in-class for Android OEMs though, so much so that Google is also expected to utilise the Snapdragon W5 Gen 1 in the Pixel Watch 2.

On the other hand, Oppo will pair the Snapdragon W5 Gen 1 with 2 GB of RAM, a doubling from the 1 GB of RAM found in the Watch 3 Pro. Thus, the Watch 4 Pro is likely to feel snappier than its predecessor courtesy of faster app loading times and smooth animations. Additionally, Oppo will complement these components with a BES2700 Bluetooth SoC and an LTPO AMOLED display to maximise battery life.

Moreover, Oppo promises to include a 16-channel blood oxygen sensor in the Watch 4 Pro, an improvement over the 12-channel equivalent in the Watch 3 Pro. Elsewhere, the Watch 4 Pro will feature a stainless steel case, 10 professional sports modes, an 8-channel heart rate sensor, ECG capabilities and a skin temperature sensor. Oppo has not revealed the Watch 4 Pro's design yet, although we imagine that it will closely resemble that of last year's model.
