Nothing's sub-brand CMF launched the Watch 3 Pro at Rs 7,999 in India, featuring a new optical heart-rate sensor that the company claims is up to 7% more accurate during activity and 3.6% more accurate at rest than previous models. The 1.43-inch AMOLED watch includes dual-band GPS, 131 sports modes, sleep tracking, SpO₂ monitoring, and a 350mAh battery.
In testing, the heart-rate readings were similar to those from a pulse oximeter, and the GPS locked within seconds. Sleep tracking distinguished between REM and deep sleep stages, while the Activity Score converts heart-rate data into a daily measure over a seven-day view. CMF states all health features are for personal reference only, not medical diagnosis.
Indian Opinion Analysis
The smartwatch market at this price point is crowded, with the Samsung Galaxy Fit3 and Xiaomi Smart Band 9 Pro both offering heart-rate and SpO₂ tracking for around Rs 5,000-9,000. Mint's reviewer found CMF's optical sensor comparable to a pulse oximeter, which is a consumer device, not clinical-grade, the company's own disclaimer bars medical use. World Heart Day is an awareness event, not a regulatory deadline. The real benchmark will be long-term reliability: the Bureau of Indian Standards has no specific smartwatch accuracy standard, so any claim of improved tracking is self-reported by the manufacturer. Buyers should check the Nothing X app data consistency over weeks, not days.
