If you’re looking for a watch that is both stylish and useful, the CMF Watch 3 Pro is certainly worth a look as it is currently back to its lowest price (purchase link under the specs table down below).
One of the headline features here is the improved optical sensor. It captures more detailed light signals beneath the skin, which translates into more accurate heart rate readings. The company notes that during exercise, accuracy improves by around 7 percent compared to earlier models, and at rest, about 3.6 percent.
For sleep tracking, the Watch 3 Pro uses enhanced motion sensors and high-frequency heart rate sampling to better recognize short naps and distinguish sleep stages. Nothing says there"s a high-precision mode too for deeper analysis which could come handy if you’re trying to understand irregular sleep patterns.
On the utility side, the watch includes dual-band GPS. That’s useful if you’re outdoors often since it helps reduce signal drift compared to single-band systems. Bluetooth calling is supported too so you can take calls directly from the wrist without pulling out your phone.
The display is a 1.43‑inch AMOLED panel with Always-On options but despite that, battery life is quoted at up to 13 days under typical use. The full technical specifications of the CMF by Nothing Watch 3 Pro are given in the table below:
