Samsung Galaxy Watch 4 44mm SM-R870 Silver White
Track your fitness progress with the first Samsung smartwatch that conveniently measures body composition, letting you know from your wrist your body fat percentage, muscle mass, the amount of water in your body and more.
The Samsung BioActive sensor and Samsung's fastest chip bring the most innovation seen in a Galaxy Watch to date.
Body composition measurement
The key to being the best version of ourselves is to keep getting to know ourselves every day. That's why Samsung has designed the new Galaxy Watch4, so that you can finally find the perfect travel companion for your healthiest self. Don't just listen to your body, get to know it! Samsung's new BioActive sensor captures your body composition in real time to inform you of your health goals. So you can get BIA measurement with just two fingers in as little as 15 seconds. Anytime, anywhere!
*Do NOT measure your body composition if you have a pacemaker or other implanted medical devices. Do NOT measure your body composition if you are pregnant. Measurement results may not be accurate if you are under the age of 20. BIA availability may vary by country or region.
Share your improvements with your loved ones and help each other advance through the Galaxy Watch4. Track your steps and challenge your friends to a fun competition via a live message board. Challenges include commemorative badges and a points system to make exercise fun, motivating and enjoyable together.
Daily activity and fitness tracking
Think of a workout: the Samsung Galaxy Watch 4 can track it. Track your activities and fitness results on your watch and phone! Count steps, check calories and locate yourself on the map with the GPS. Galaxy Watch4 detects physical activity to track your routines and supports over 90 exercises for more accurate reporting of your workouts.
Blood pressure and ECG
You know what else the Samsung BioActive sensor on the Watch4 does? It measures ECG and blood pressure in real time. Yes... After initial calibration, the sensors quickly check your blood pressure. In addition, it can check for abnormal heart rate and rhythm via ECG and send the data directly to your phone for easy sharing.
*Intended for general wellness and fitness purposes only. Not intended for use in the detection, diagnosis or treatment of any medical condition or disease. Measurements are for personal reference only. Consult a medical professional for advice. The ECG and BP features can only be used by persons that are 22 years old and older. To obtain accurate BP readings, calibration with monitor and blood pressure monitor is required every 4 weeks. Requires a Galaxy smartphone running Android 7.0 or higher. Users should measure their blood pressure at rest, as they would with a traditional blood pressure monitor, and refrain from measuring blood pressure when exercising, smoking or drinking.
The most comprehensive sleep analysis is on your Galaxy Watch
The sleep tracker also comprehensively detects and analyses the phases of your sleep as you rest. Enhanced measurement options let you check your blood oxygen levels and snoring patterns (but we're not saying you snore!). Plus, get advanced information from the National Sleep Foundation to improve your sleep quality and duration.
*The Advanced Sleep feature is for fitness and wellness purposes only and is not intended for the detection, diagnosis or treatment of any medical condition or disease. Consult a medical professional for advice. Galaxy Watch4 must be paired with a smartphone to use the sleep management feature. For best results in detecting and recording snoring, place the smartphone on a stable surface near your head with the bottom of the smartphone pointing towards your head.
Sleek, seamless, iconic
The Galaxy Watch4, on the other hand, features a simple design with its armoured aluminium metal frame, offering a high-end look for both your workouts and everyday tasks.
This model is accompanied by the Sport Band, a high-quality silicone strap with a comfortable fit and sweat-resistant surface. It can be easily replaced with a compatible strap for this model.
*Not compatible with universal bands. Watch4 uses a specifically designed strap.
A new watch with a new face every day
And if you wear different clothes every day, why not change the look of your smartwatch too? Choose from analogue or digital watch faces with a variety of backgrounds, fonts and colours to suit your taste, the weather or the occasion. Liven up your watch face with AR emojis to show off your style, while expressing what you're doing with animated graphics, such as running or listening to music.
Wear OS, the new operating system
As Samsung's first smartwatch with Wear OS, Galaxy Watch4 puts your favourite apps right at your wrist. You'll have a full selection of apps, from music players to any app you can imagine available in the huge library of health and fitness apps.
What's more, this also allows you to perfectly connect with other Samsung Galaxy devices: control the Galaxy Buds2's active noise cancellation or activate your phone's apps directly from the watch. Plus, additional features like the compass make the Galaxy Watch4 an endless source of ingenuity.
