Not just a pretty face

With an understated metal frame and flat, circular display, your Samsung Galaxy Watch4 looks the business no matter what you’re doing – available in a variety of colours to suit your style. The display automatically adjusts its brightness for the best view, whilst also conserving power. And, with the screen’s improved clarity, you’ll see more crisp detail in all your favourite apps.

The health coach that never clocks out

The Samsung Galaxy Watch4 Series and Samsung Health invite you to learn more about your body so you can understand it better. With body composition, ECG and Blood Pressure measurements*, and blood oxygen level tracking, it’s never been easier to track your wellbeing goals and explore what’s going on under the surface. When you need a bit of motivation to get your trainers on, daily activity reports and group challenges provide that extra push. And, with exercise tracking, your PB won’t be your best for long. You can even work towards a healthier lifestyle when tucked up in bed, with advanced sleep insights and snoring detection. * ECG and BP feature only to be used by 22 years+. For accurate BP readings, monthly calibration is required by a GP or a BP monitor and arm cuff. Requires a Galaxy smartphone running Android 7.0 or above.

Do more with less

You’ll never need to rummage through your bag for loose change, thanks to Samsung Pay – just tap, pay and go. Receive or reject calls on your wrist and see all your social notifications at a glance. And with the 4G variant you can do it all without your phone. A long-lasting battery lets you go further between charges, and 16GB of internal storage offers enough space to play thousands of songs offline. Link up to your phone’s SmartThings app to wirelessly control your connected tech at home, no matter where you are. And, with SmartThings Find, you can keep tabs on your Galaxy Watch4 when it’s not wrapped around your wrist.

Our most powerful watch OS yet

The clean and simple UI provides fast access to all your favourite apps striking a fine balance between productivity and wellness. It also means seamless integration with your other Android-powered devices, with all your apps from the Play Store being automatically installed. This is the perfect partnership, for a smoother experience that runs on your time.
