A smartwatch with precision rotating bezel for app navigation

Pick between 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.5

Bigger display, but also lighter and slimmer for a comfortable fit.

Outlined in a subtle rotating bezel, it's easier to focus on what matters with a bigger screen. Galaxy Watch3 is thinner, smaller and about 15% lighter with a sophisticated look that's ideal for your wrist with its slimmed down frame.6

Premium quality, down to the strap

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.

When beautiful meets intelligent

The Galaxy Watch3's offers a large number of watch faces to choose from, all matching its sleek body. Make your own combination with over 40 combinations, your favourite apps are conveniently viewable with a quick glance.* *Accessories sold separately.

Equipped with over 120 home workout programs to choose from, Galaxy Watch3 helps you get your body moving on your time. Pick from your phone and cast to your TV – as you work out, it'll display your heart rate in real time. Use the Ridge Sport Band for even more accurate stats.13, 14, 15, 16, 17

The beat goes on and on

Your music doesn't stop as you go from one device to another. Play Spotify on your Galaxy Note20 5G, 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.28, 29, 30, 31
