The only smartwatch with precision rotating bezel for app navigation

  • 41mm


Bigger display, Yet lighter and slimmer for comfortable wear

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, 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.



Beauty with smarts to match

Fall detection that won't fall down on the job

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.11

Keep the conversation going

When you get a new text, Galaxy Watch3 shows your chat history so you can effortlessly follow the conversation. You can also see images without an extra tap, making it even easier to keep the mood going while on a run.18, 19



Add a little context with smart reply

Stay connected with others even on the go – and without wondering how to reply. Galaxy Watch3's smart reply analyses texts and photos you receive and gives you suggested replies, supporting different categories that include food, celebrations, selfies, and more.20, 21



More fun in your messages

Bitmoji stickers open up fun new ways to communicate. Personalise your Bitmoji to look just like you and use Bitmoji stickers to jazz up the way you talk to family and friends.22, 23, 24, 25, 26



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, 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.27, 28, 29, 30
