Overview

Get to know what
makes you tick

Get to know yourself better than ever before with Galaxy Watch4. Onboard trackers let you build up an accurate all-round picture of your health - from new body composition measurements (BIA) and blood oxygen levels during sleep, to ECG and Blood Pressure monitoring1. And with enhanced screen quality and refined design, the range is more versatile than ever. Not to mention all the best bits of Samsung too, including SmartThings Find and Samsung Pay.

Not just a pretty face

With its slim profile, smooth lines and flush glass, Galaxy Watch4 is the perfect all-rounder. Designed for comfort during your workout and smart-casual dress in the evenings. With an understated metal frame and flat, circular display, 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, so you’ve always got the best view while conserving power. And with the screen’s improved clarity, you’ll see more crisp detail in all your favourite apps.

Health features
packed under
the hood

With Samsung Health, get to grips with how your body works and what it needs to maximise your health and wellbeing. Galaxy Watch4 helps you learn more about your body so you can understand it better. With body composition, ECG and Blood Pressure measurements1, and blood oxygen level tracking, it’s never been easier to track your wellbeing goals and explore what’s going on under the surface.

The fitness coach that never clocks out

When you need a bit of motivation to get your trainers on, daily activity reports and group challenges on Galaxy Watch4 provide that extra push. And with exercise tracking on board, your PB won’t be your best for long. You can even build towards a healthier lifestyle when tucked up in bed, with advanced sleep insights and snoring detection.

* Galaxy Watch4 Classic must be paired to a device with Android 8.0 or above and be in close proximity on a stable service.

Connectivity
on your wrist

Streamline your daily routine with a massive range of extra features, wireless connectivity for Buds and SmartThings Find. With Samsung Pay on board, you’ll never need to rummage through your bag for loose change - just tap, pay and go. Receive or reject calls on the wrist and see all your social notifications at a glance. And with the 4G variant you can do it all without your phone2. What’s more, a long-lasting battery lets you go further between charges, and 16GB of internal storage offers enough space to play thousands of songs offline.
