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, see strengthened leather that protects against discoloration.

Take your health into your own hands, with your wrist
Check your blood pressure via the Samsung Health Monitor App without regularly needing a cuff. Before first use simply calibrate with a cuff, then smart sensors measure your blood pressure through pulse wave analysis as you wear it. Check it daily to track trends and get reports right on your phone.7, 8, 9, 10, 11
Touch the watch's back button for up to 30 seconds to have its built-in electrode sensor measure your heart rhythm. This ECG on the go tests for atrial fibrillation (Afib), then shows your measurements at a glance. See results over time from your phone, get the report, and share for more insights.12, 13, 14
Galaxy Watch3 uses red LED and infrared rays to estimate your SpO2 levels, or the amount of oxygen in your bloodstream. Because this oxygen saturation is directly linked to physical performance, you can use Galaxy Watch3 to push your routine to the next level.15, 16, 17

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.38, 39, 40, 41
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.42
