Overview

Look good. Feel great.
We all want to know more about ourselves, so we can be the best version of ourselves. That's why we engineered the all-new Galaxy Watch4 Classic to be the stylish companion to your journey towards a healthier you.

All the data your heart desires
Be smart about your heart. Meet the Samsung BioActive Sensor that measures ECG in real time. You can check and monitor abnormal heart rate and rhythm through ECG and send data straight to a compatible Galaxy phone to be easily shared.

Measure blood oxygen levels from your wrist
Built-in blood oxygen measurement on Galaxy Watch4 lets you check the amounts of oxygen in your bloodstream at any time. Oxygen saturation is directly linked to physical performance, so monitoring your blood oxygen can help you maintain your health.

Better sleep starts here
Manage your overall sleep quality with an advanced sleep tracker that detects and holistically analyzes your sleep stages while you rest. Improved measuring options let you check your blood oxygen levels and detect if you are snoring.

Your coach to bedtime bliss
Learn how to develop healthy sleep habits with Sleep coaching. By tracking your sleep patterns and completing sleep surveys, our program assigns 1 of 8 sleep symbol animals that represents your sleep type. It then provides a 4 to 5 week coaching program with helpful sleep tips, missions and checklists.

Timeless style. Elevated design.
Some looks are timeless, like Galaxy Watch4 Classic’s rotating bezel and vivid screen. Stay comfortable and fashionable all day long with our stylish bands including the Ridge Sports Band.
