They are the first smartwatches to feature the new Wear OS™ Powered by Samsung, designed in conjunction with Google™, and are equipped with One UI Watch, Samsung's most intuitive user interface yet. The Galaxy Watch4 series is bolstered with advanced hardware performance and delivers a more seamless and connected user experience than ever before. These new devices have been completely redesigned to offer consumers the best tools to manage their well-being.

“We have seen an incredible amount of growth for the Galaxy Watch series as consumers have discovered the health benefits and convenience of wearable devices,” said Dr. TM Roh, President and Business Leader of Mobile Communications at Samsung Electronics. “We understand that the path to wellness is different for everyone, so we've created a robust set of health and wellness features to give people a deeper, more useful understanding of their overall fitness.”

Samsung's most advanced set of health and wellness features
Galaxy Watch4 is equipped with Samsung's innovative BioActive sensor, which has a smaller, more compact design that does not compromise measurement accuracy. This new 3-in-1 sensor uses a single chip to precisely run three powerful health sensors – Optical Heart Rate, Electrical Heart and Bioelectrical Impedance Analysis – so users can monitor their blood pressure, detect an irregular AFib2 heartbeat, measure their blood oxygen level and, for the first time, calculate their body composition. Our new Body Composition measurement tool gives users a deeper understanding of their overall health and fitness, with key measurements such as skeletal muscle, basal metabolic rate, body water, and body fat percentage. Now, you can easily check your body composition from your wrist with just two fingers. In about 15 seconds, your watch's sensor will capture 2,400 data points.

These smartwatches come with a variety of wellness features to track your daily activities to keep you motivated to be your best self. Choose from a wide range of guided workouts, enjoy Group Challenges with your friends and family, or set up a home gym by connecting your Galaxy Watch4 to your compatible Samsung Smart TV, where calorie counts and heart rate metrics appear on the screen for easier tracking. And when you're ready to rest, the Galaxy Watch4 series offers our most complete picture of your sleep standards, with more detail than before. Your compatible smartphone detects the sounds of your snoring, while your smartwatch measures your blood oxygen level when you sleep4. Along with advanced Sleep Scores, you can learn more about your sleep standards so you can rest better.

The ultimate mobile experience, with One UI Watch and Wear OS Powered by Samsung
Simplicity, ease and efficiency are hallmarks of the Galaxy smartwatch platform, and with Samsung's new One UI Watch and Wear OS Powered by Samsung, we've made the smartwatch and Galaxy experience even more seamless. With One UI Watch, compatible apps are automatically installed on your watch when they are downloaded to your phone, and your important settings – like do not disturb hours and blocked calls – are instantly synced. Auto Switch ensures that the headphones can switch audio between the phone and the watch, depending on use. You can also effortlessly control your mobile experience with Bixby's voice, bezel, and gesture controls. Move your forearm up and down twice to receive calls and rotate your wrist twice to reject them or dismiss notifications and alarms.

The Galaxy Watch4 series is also the first generation of smartwatches to include Wear OS Powered by Samsung, a new platform that elevates all aspects of the smartwatch experience. Powered by Samsung and Google, this cutting-edge platform lets you access an expansive ecosystem right from your wrist, with popular Google apps like Google Maps, and beloved Galaxy11 services like Samsung Pay, SmartThings, and Bixby. The new platform also includes support for leading third-party apps12, such as adidas Running, Calm, Strava and Spotify available on Google Play. Coupled with our advanced hardware and an even more intuitive user interface, you can enjoy seamless and convenient integrated experiences with your Galaxy Watch4. For example, our refined built-in compass works in conjunction with Google Maps to make it easy to explore a new area.

Bringing powerful performance right to your wrist
This incredible experience is backed by major hardware upgrades, including improved processor, richer displays, and expanded memory. The Galaxy Watch4 series features the first 5nm processor in a Galaxy Watch, with a 20% faster CPU with 50% more RAM, and a 10x faster GPU than the previous generation. This means that scrolling and multitasking on the Galaxy Watch4 series is fluid and effortless. We've also increased the screen resolution, up to 450 x 450 pixels, to make images sharper and more distinctive. And with an impressive 16GB of memory, you'll have enough storage to download and store your favorite apps, music and photos, confident that they're safe thanks to Samsung's security platform, Knox.

Samsung's leadership in eSIM technology enables users to enjoy the freedom of forgetting their phone, knowing that their smartwatch will automatically sync and fill the gap. We also know that a reliable battery is essential for a smartwatch. It can have up to 40 hours[14] of battery life, which is more than enough to keep you charged on an overnight camping trip, even supporting the fastest processor, highest resolution display, expanded memory, and more sophisticated health features. And when you need more power quickly, 30 minutes of charging provides up to 10 hours of use.
