Bigger display, Yet lighter and slimmer for comfort wear

Take your health into your own hands, with your wrist

Follow your heart rhythm with ECG monitoring

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.

*Requires Galaxy smartphone, running Android 7.0 OS or above, and Galaxy Watch Active2 or upcoming Galaxy Watch device(s) to be paired. *THE ECG RECORDING OR SAMSUNG HEALTH MONITOR APP IS NOT INTENDED TO DETECT A HEART ATTACK. IT IS NOT INTENDED TO REPLACE TRADITIONAL METHODS OF DIAGNOSIS OR TREATMENT.*Availability may vary by market. (Currently available in Korea. Will be available in the USA and other countries after obtaining regulatory clearance/approval/grant.)

Breathe easier with built-in oxygen measurement

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.

*Feature not supported in Japan, Angola, South Africa, Thailand, Iran, Libya, France, Algeria, and Brazil.
*Availability may vary by country or region.
*SpO2 is defined as saturation of percutaneous oxygen. Normal levels in humans are measured at approximately 95-100%. Factors like vigorous exercise, the amount of oxygen in the air, your elevation, and various health conditions can all result in lower readings.

Fall detection that won't fall down on the job

Explore fearlessly. Galaxy Watch3 automatically detects hard falls with its enhanced accelerometer, sending an SOS to your emergency contact with your location.

*Galaxy Watch3 can initiate Emergency call and message if you take a hard fall and don't seem to move.
*Galaxy Watch3 cannot detect all falls.
*The more physically active you are, the more likely you are to trigger Fall Detection due to high impact activity that can appear to be a fall.
*Sending SOS calls and messages requires network connection and smartphone pairing.

Get a better night's sleep

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.

*Sleep management functions (REM cycles, deep sleep, and total sleep time) on the watch can be used as standalone, but smartphone pairing is recommended in order to see sleep score. Insight only available on paired smartphone.

Hit your best, then do it again

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.

*Fitness tracking on the watch can be used as standalone, but data stored in the watch may only be partially displayed after a certain period of time. Smartphone pairing is recommended in order to keep all data stored.
*Intended for general wellness and fitness purposes only.
