CMF by Nothing Watch 3 Pro

Design that moves with you

With a precision-milled metal frame, Watch 3 Pro has a confident yet lightweight feel on the wrist. It's shaped to sit comfortably and styled to blend into any outfit, situation, or occasion. Paired with soft-touch silicone straps, it's made for all-day wear and effortless transitions.

Larger, brighter, better

The 1.43-inch AMOLED display is our most immersive yet. With a smooth 60 fps refresh rate, it delivers clarity and responsiveness at every glance. Auto-brightness adapts in real time, and with a 91 percent screen-to-body ratio, it feels more expansive without adding bulk.

Watch faces that reflect you

With over 120+ custom watch faces, including animated, interactive and Always-On Display versions, Watch 3 Pro becomes your canvas. Choose based on the day, your mood or your look. Every face is designed to feel personal and fluid.

Everyday health insights

Watch 3 Pro helps you stay aware of your body, day and night. From blood oxygen and stress levels to heart rate, it's designed to support you. All your wellness insights in one place, ready when you need them.

Advanced heart rate monitoring

A new optical sensor captures more detailed light signals and finer variations in blood flow from beneath your skin. That means more accurate heart rate tracking, especially during high-intensity workouts, light skin contact and across an array of skin tones. With better signal clarity, readings are up to 7% more accurate during exercise and up to 3.6% more accurate at rest compared to previous generations.

Smarter sleep monitoring

Rest is just as important as movement. Watch 3 Pro tracks your sleep more precisely thanks to enhanced motion sensors and high-frequency heart rate sampling. It recognises short naps, detects your sleep stages more accurately, and now includes a high-precision mode for even deeper analysis. Enable it when you need the most detailed sleep tracking and wake up with a clearer picture of your rest.

Active Score

Track your weekly activity with one simple number. Active Score uses heart rate data and MET values (Metabolic Equivalent of Task) to combine activity intensity and total movement, giving you a reflection of your overall physical activity.

The score updates every day and after each session, so you can see how each effort adds up. Whether it's walking, weight training or interval runs, it gives you a clear picture of progress. The weekly goal is 100, a simple benchmark aligned with global health standards to help keep you moving, consistently.

Expanded health tools

Stay on top of your wellness with 24/7 tracking of blood oxygen (SpO₂), stress levels and heart rate zones. Hold space for yourself with guided breathing sessions, while water and stand-up reminders encourage healthier daily habits. Women can also receive intelligent prompts to track and predict menstrual cycles, helping make everyday health feel more informed and intuitive.
