And with Galaxy Watch3 4G, you’re always connected, even when you don’t have your phone on you. Stream the latest Spotify tunes on your way to work, and call your friends to plan your next hangout – all with your watch. Galaxy Watch3 keeps you on top of it all, wherever you are. 1

As the 45mm Galaxy Watch3 in Mystic Black rotates, it turns into a 45mm Galaxy Watch3 in Mystic Silver with an Analog Modular watch face.

lighter design

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 lighter than its predecessor, with a sophisticated look and slimmed down frame.

BLOOD PRESSURE

Monitor and track your blood pressure3

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.
