The perfect companion for your wrist
The watch that watches out for you. Galaxy Watch3 combines smartphone-level productivity and leading health technology in one premium and classic device. Our most advanced Galaxy watch yet, Galaxy Watch3 helps you effortlessly manage your life and health — putting your well-being in your hands.
Take your pick of two sizes, 45mm or 41mm, each with a face you won't soon forget. Available in premium Mystic Black, Mystic Silver, and Mystic Bronze hues, the elegant design is outlined in a unique rotating bezel for a look that works around the clock.
Outlined in a subtle rotating bezel, it's easier to see and focus on what matters with an even bigger screen. Galaxy Watch3 is thinner and smaller, yet about 15% lighter with a sophisticated look that's ideal for your wrist with its slimmed down frame.
Galaxy Watch3's design is polished off with a premium genuine leather strap. Aged leather creates a natural look, and when you turn it over, you'll see a strengthened leather which helps protect against discoloration.
Complete Galaxy Watch3's signature look with the largest number of watch faces to choose from, all designed to match its sleek body. Make your own combination with over 40 different watch faces. View the useful information you need at a glance, while easily accessing your favourite apps.
Take your health into your own hands, with your wrist

Galaxy Watch3 records your REM cycles, deep sleep, and total sleep time to score and help improve the quality of your rest. Samsung partnered with the National Sleep Foundation to include educational content and sleep tips right on your device, to help you understand and improve your sleep.
Equipped with over 120 home workout programs to choose from, Galaxy Watch3 helps you get your body moving on your time. Pick a routine from your phone and cast it to your TV. And, as you work out, the Watch3 will display your heart rate in real time. For even more accurate stats, use the Ridge Sport Band.
Galaxy Watch3's running guide lets you keep pace as you get tips on the go. The advanced algorithm analyses how you move to help improve your form and prevent injuries. You can even measure VO2 max values and keep up with your daily, weekly, and monthly performance right from your phone.
Smartphone-level power is now within reach
Your music doesn't stop as you go from one device to another. Play Spotify* on your Galaxy Note20, then open it with the Spotify app icon on your watch face to easily switch songs from your Galaxy Watch3. Or you can even touch and hold Galaxy Buds Live to get lost in the music.
Put together a team of Galaxy Apps to join you and your phone in your day-to-day. Find your phone and see your phone's photos from your watch, or switch between devices to control your music and check reminders. The perfect partners are all on your wrist.
Go out for new experiences without the weight of your phone. You can still call, stream, and check your steps — all from your watch. Disconnect from your phone, while staying connected with life.
