CMF by Nothing smartwatch Watch 3 Pro

Key points

The 1.43-inch AMOLED display gives workout stats, messages, and health data a dedicated place on your wrist, while GPS and 130+ sport modes make the Watch 3 Pro more than a basic step counter.

It also supports Bluetooth calls through a built-in speaker and dual microphones. That can be handy when your hands are busy, though it’s still a watch-first way to stay connected, not a replacement for every phone task.

Health tracking includes heart rate, blood oxygen, stress, and sleep data. Treat those as everyday wellness insights, not a medical assessment, the product details don’t establish medical-grade accuracy.

How to use it

Pair the watch with an Android phone or iPhone through the Nothing X app, then choose the health tracking, widgets, reminders, and watch face that suit your routine. The listing also names Apple Health, Google Health Connect, and Strava for syncing, which may help if you already use one of those services to keep activity data together.

For a workout, select one of the available sport modes and use the activity tracking to review movement and training information afterward. At work or while cooking, Bluetooth calling and music controls give you a way to handle a quick task without reaching for your phone. You can sync up to 30 contacts for quick access.

The listing says battery life is up to 13 days for daily use and charging takes 2.5 hours. Actual runtime can vary with how you use the watch, so frequent calls, tracking, or other active features may make that maximum less relevant to your routine. On the spec sheet, it covers more than basic activity tracking, but it doesn’t explain how each feature affects battery life.

Practical tips

A useful test of fit is your own weekday: imagine checking a workout, glancing at a message, then taking a short call while your phone stays in a bag. The Watch 3 Pro’s mix of sport tracking and wrist-based calls is aimed at that kind of day. If you mostly want a simple step count and time display, its broader health and workout tools may be more than you need, a simpler band or watch could suit that lighter use better.

A solid pick if you want a single wearable for workouts, sleep insights, and quick Bluetooth calls, and you’re comfortable using an app to manage settings and data. It might not be a great match if you need confirmed medical measurements or detailed information about how tracking features affect battery life. The product name lists IP68, but the supplied details don’t explain care instructions or specific water-use conditions, so don’t infer more than the rating provided.

Before you decide

Does it work with iPhone? The product details say it supports Android and iOS, and name Apple Health among its sync options.

Can you take calls from the watch? Yes. It has a built-in speaker and dual microphones for Bluetooth calls, and supports syncing up to 30 contacts.

What workout tracking does it offer? The listing describes 130+ sport modes, activity tracking, and performance analysis, along with heart rate and sleep monitoring.

Final verdict

Choose the Watch 3 Pro if you’ll use its combination of GPS, broad sport tracking, wellness insights, and Bluetooth calling rather than just glance at the time. Its 1.43-inch AMOLED display and stated battery life make it suited to regular everyday wear, but the available information leaves some practical questions—especially around water-use guidance and battery impact from individual features. If those details are decisive, a more fully documented device may be the safer fit.
