OPPO Watch 2 ECG Edition: the electrocardiogram reaches the most ambitious smartwatch of the brand

OPPO’s adventures in the smartphone field began last year with the OPPO Watch, which was later renewed by the OPPO Watch 2. The latter was a considerable leap at the hardware level and the brand now presents the OPPO Watch 2 ECG Edition, a new version that has an electrocardiogram function.

With this addition, OPPO places its most ambitious watch to date at the level of competing with the most complete smartwatches of the competition, since the ECG has been added and becoming one of the main claims of these devices, as in the case of the Apple Watch Series 7 or the Samsung Galaxy Watch 4. The rest of the configuration is already more familiar, although yes, the starting price is higher than the version without ECG.

Detecting the rhythm in large wrists

It does not have to be exactly like that, but OPPO’s movement with its Watch 2 is only framed in the 46 millimeter model, the largest of the sizes of its predecessor (42 and 46 mm). However, the design remains unchanged, with very Apple Watch corners and the same 1.91-inch AMOLED screen and 372 x 430 pixel resolution.

The new sensor is responsible for adding the function of performing a real-time ECG, being able to give some indication about cardiac anomalies, always taking it as a non-medical device and with the need to consult a professional in case something is seen irregular as well. The way to do it is similar to the ones we have seen in previous proposals: place your finger on the side button.
