Dizo is Realme's latest sub-brand for 'ecosystem' devices, mostly lifestyle wearables thus far. To this end, a Watch 2 and Watch Pro under this new name have been unveiled. They offer large displays and health-tracking tech such as SpO2 monitors, although the Pro has more sports modes and a larger battery. They will sell in India via Flipkart from late September 2021.
