Popular questions about CMF Watch 3 Pro

Verified 7 september, Serhii Shkurupii

How long does the battery last on the CMF Watch 3 Pro in real-world use?

The manufacturer claims up to 13 days in normal mode, while in an active usage scenario with the screen constantly on, workouts, and sleep tracking, the watch lasted just over four days. A full charge takes about 99 minutes, so you won’t have to charge them every night.Source:SpecificationsExpert reviews

Can I pay with my watch in a store?

CMF Watch 3 Pro do not support contactless payments because they do not have NFC. They can receive Bluetooth calls, display notifications, and control certain phone functions, but you will need a smartphone or card to make payments.Source:SpecificationsExpert reviews

Are the CMF Watch 3 Pro suitable for running without a phone?

Yes, you can record your route without a smartphone thanks to dual-band GPS with L1 and L5 support. The watch offers 131 sports modes and provides approximately 17 hours of GPS runtime, making it suitable for regular runs and long walks.Source:SpecificationsExpert reviews

How accurate are the heart rate measurements on the CMF Watch 3 Pro?

The watch is suitable for monitoring overall exertion, but its readings should not be regarded as an exact medical result. Compared with a chest-strap sensor, the peak heart rate usually differed by 1–2 beats per minute, while the average value sometimes differed by approximately 5 beats.Source:Expert reviews

Is it convenient to review your workout results after exercising?

On the CMF Watch 3 Pro, workout records can be viewed on the watch itself, but access to detailed workout history in the smartphone app is limited. For someone accustomed to analyzing pace, heart rate, and progress on a large screen, this will be a noticeable compromise.Source:Expert reviews

Can I swim in a pool?

The CMF Watch 3 Pro have IP68 protection, but are not designed for swimming in a pool or water-based workouts. They are suitable for running, gym workouts, walks, and everyday wear, while swimmers should choose a model with explicitly stated support for this use case.Source:SpecificationsExpert reviews
