Yes, is it worth buying but keep in mind, this is just a fitness tracker with a bigger display. Its perfect watch if your budget is Under Rs 5,000 as it offers almost everything that budget watch should have.
Bluetooth calling is there and yes, its not the best. For ex, if you're in public place then its will be hard to hear someone on call because the speaker doesn't go too loud.
AT home, there won't be any sort of problems because mostly, there won't be too much noise when you're at your home.
The battery life is solid too, expect around 3 days with heavy usage while with normal usage, it will really last for 7 to 10 days.
It has built-in GPS with support for 5 satellite positioning systems, IP68 rating, heart rate monitoring, sleep tracking, SpO2 monitoring, step counting, and 110 sports modes.
The SpO2 doesn't work the best in a budget smartwatches and the same can be said for the heart rate as well.
Now, Nothing has used good quality sensors but in the end, they're optical sensors that are not great, if you have serious health issues and you're relying on this watch or any other budget smartwatch.
What I'm saying is, the CMF Watch Pro provides better accuracy compared to other budget smartwatch under 5k.
Now, yes, the accuracy will get better once Nothing updates this watch. Also, Notying has a good record of improving their products with OTA updates too.
By the way, the built-in GPS take 20 or even more second to locate the correct location which is odd and I'm hoping that it will get fixed every soon.
So yes, you can consider this watch if your budget is under Rs 5000.
CMF by Nothing Watch Pro is the first smartwatch from CMF by Nothing and it’s Nothing new, it’s a generic smartwatch that,
can make and receive calls with the help of Bluetooth while heart tracking is hit or miss. Nonetheless, Rs 4,499 ($69) is the justifiable price for what Nothing is offering.
