Everyday tools, always on hand

Designed to simplify daily life, Watch 3 Pro includes practical features like camera controls¹³, to-do reminders, weather updates and a world clock. You also get a flashlight, stopwatch, calculator and timer built in. Music controls with on-screen widgets make it easy to manage playback from your phone. And for peace of mind, Find My Phone and Do Not Disturb modes are just a tap away.

Bluetooth calling with noise reduction

Make and receive calls directly from your wrist with exceptional clarity. Watch 3 Pro features two high-performance MEMS microphones and a built-in speaker, enhanced by AI-based noise reduction trained on over 100,000 voice samples. Even in noisy outdoor environments, your voice stays front and centre. You can also sync up to 30 contacts for instant access to the people who matter

Quick replies and notifications

Stay connected without reaching for your phone¹⁰. Watch 3 Pro lets you send short messages directly from your wrist, using preset or personalised responses. Whether it’s a quick update on WhatsApp or a casual reply on Instagram⁶, it’s an easy way to keep conversations flowing throughout your day

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
