CMF Watch 3 Pro

The CMF Watch 3 Pro features a 1.43″ OLED/AMOLED touchscreen with a resolution of 466 x 466 pixels and a pixel density of 326 ppi, and it supports an always-on display mode for continuous visibility. The watch body measures 45 mm in height, 47 mm in width, and 14.4 mm in thickness, with a total volume of 30.456 cm³ and a weight of 51.9 g, keeping it reasonably light on the wrist. It holds a 5 ATM water resistance rating alongside IP68 certification, making it capable of handling submersion and exposure to water, though it does not feature branded damage-resistant glass or sapphire glass over the display. The watch band is replaceable, offering some flexibility in customization, and the device is not designed for children.

The CMF Watch 3 Pro includes a solid set of onboard sensors suited for both everyday health monitoring and outdoor activity. It features a heart rate monitor and a pulse oximeter for tracking cardiovascular activity and blood oxygen levels, while a gyroscope and accelerometer work together to capture motion and orientation data accurately. A built-in compass adds directional awareness, and GPS is present for location and route tracking without relying on a paired phone. The watch does not include a body temperature sensor, barometer, cadence sensor, or perspiration monitor.

The CMF Watch 3 Pro covers a broad range of activity tracking capabilities suitable for varied training routines. It tracks steps, distance, pace, and elevation, and includes a route tracker for mapping outdoor sessions, while automatic activity detection means workouts can be logged without manual input. Sleep tracking is supported alongside detailed sleep reports, giving users a clearer picture of their rest patterns. The watch also features multi-sport mode with exercise tagging, and swimmers benefit from a built-in stroke counter. On the nutrition side, calorie intake tracking is available as well. It is not designed for diving or golf specifically.

The CMF Watch 3 Pro connects to smartphones via Bluetooth 5.3 and is compatible with both Android and iOS devices. For satellite positioning, it supports the Galileo navigation system in addition to its onboard GPS. The watch does not include a cellular module, so it relies on a paired phone for data connectivity, and it lacks Wi-Fi support as well. NFC and ANT+ are also absent from its connectivity feature set.

The CMF Watch 3 Pro is equipped with a 350 mAh rechargeable battery that is neither removable nor solar-assisted. Under standard use, it is rated for 13 days of battery life, while power save mode extends that figure significantly to 1,440 hours. In training mode the watch lasts up to 108 hours, and with GPS continuously active, endurance reaches 17.2 hours. Charging is done via cable — wireless charging is not supported — and a full charge takes approximately 1.65 hours.

The CMF Watch 3 Pro offers a well-rounded set of health and convenience features. On the health monitoring side, it tracks HRV, VO2 max, and resting heart rate, and sends fast and slow heart rate notifications, though it does not support ECG technology, irregular heart rate warnings, or fall detection. For daily use, the watch handles wrist notifications, call answering and call control, a silent alarm, vibrating alerts, a stopwatch, and voice commands, while a built-in camera remote shutter adds a handy utility function. A phone-finding feature is also included. Smart alarm is not available, fast GPS lock is not supported, and the watch has no front camera. It comes with a one-year warranty.

The companion app for the CMF Watch 3 Pro is available free of charge and is ad-free, though it does require an account to use. It provides activity reports, calorie burn tracking, an exercise diary, goal setting, inactivity alerts, and an achievements system to support day-to-day fitness habits. Water intake and weight tracking are also included, rounding out the lifestyle monitoring side of the app. For female health, the app covers period notifications, fertile window notifications, ovulation prediction, and cycle start date prediction. On the other hand, it does not support coaching, temperature tracking, route planning, calendar sync, music playback, email export, app personalisation, or a barcode scanner for food logging.

The CMF Watch 3 Pro includes a battery level indicator so users can keep track of remaining charge at a glance. It does not support passcode protection, auto pause during workouts, or pairing with external heart rate monitors. There is no external memory slot for storage expansion, and the watch lacks a 3.5 mm audio jack. In terms of desktop compatibility, it is not compatible with Windows or Mac OS X.
