Dizo is a relatively new spin-off of the globally recognized Realme brand. It mostly serves to sell tech from its original OEM with a cost-effective "TechLife" appeal. This strategy must be working, as one of its latest products is now dubbed the "fastest-selling" in its market.
The Dizo Watch 2 launched as a variation on Realme's own Watch 2, albeit with a 21% larger 2.5D curved display and a different choice of strap colors. The SpO2-tracking enabled wearable originally debuted at INR 1,999 (~US$27) in India.
Clearly, this price-point was a good choice, as Realme now estimates that Dizo has moved about 100,000 units of the Watch 2 since its release. This, apparently, makes it one of the best-selling smartwatches in history to date. The brand has also now hinted at a "surprise" for its fans to celebrate this achievement. It should presumably be unveiled in the near future.
