Galaxy Watch4 and Galaxy Watch4 Classic: Reshaping the Smartwatch Experience

Aug 11. 2021

The Galaxy Watch4 series delivers a holistic suite of health and fitness features, an all-new OS and UI and enhanced hardware performance

SINGAPORE – August 11, 2021 –Samsung Electronics today announced the launch of the Galaxy Watch4 and Galaxy Watch4 Classic— marking a new era for smartwatch innovation. They are the first smartwatches to feature the new Wear OS™ Powered by Samsung, built jointly 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 provide consumers with the best tools to manage their wellness.

“As we continue to adapt in the new normal, consumers are also prioritising their health and self-care. With the Galaxy Watch4 series, users can discover a holistic suite of features that make it easier for them to lead a healthy life and take better care of themselves. In addition, the Galaxy Watch4 series features a stunning new design that gives users infinite options for personal customisation to match their style. Whether it’s the premium Galaxy Watch4 Classic with its fan-favourite rotating bezel, or the minimalist look of the Galaxy Watch4, users can mix and match the colours and style of the strap as well as switch up the watch face to match their mood, outfit, or activity,” said Sarah Chua, Vice President of IT and Mobile, Samsung Electronics Singapore.

 

Samsung’s Most Advanced Suite of Health and Wellness Features

Galaxy Watch4 is equipped with Samsung’s ground-breaking BioActive Sensor, which boasts a smaller and more compact design that doesn’t detract from 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 pressure¹,², detect an AFib irregular heartbeat³,⁴, measure their blood oxygen level⁵, and, for the first time, calculate their body composition⁶.

 

Its all-new Body Composition measurement tool gives users a deeper understanding of their general health and fitness, with key measurements like 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 packed with an array of wellness features to track your daily activities and stay motivated to be your best. Choose from a wide range of guided workouts, or enjoy Group Challenges with your friends and family. And when you’re ready to rest, the Galaxy Watch4 series offers our most complete picture of your sleep patterns yet⁷, with greater detail than before. Your compatible smartphone detects the sounds of your snores⁸, while your smartwatch continuously measures your blood oxygen level when you sleep⁹.  Together with advanced Sleep Scores, you can learn more about your sleep patterns to get better rest.

 

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 brand-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 downloaded on your Galaxy phone¹⁰, and your important settings – like do not disturb hours and blocked callers – are synced instantly. Auto Switch¹¹ ensures your earbuds can toggle audio between your phone and watch, depending on usage. You can also effortlessly control your mobile experience with Bixby voice¹², bezel and Gesture Controls. Move your forearm up and down twice to receive calls and rotate your wrist twice to reject them — or to dismiss notifications and alarms.

 

Galaxy Watch4 series is also the first generation of smartwatches to feature Wear OS Powered by Samsung —a new platform that elevates every aspect of the smartwatch experience. Built by Samsung and Google, this cutting-edge platform lets you tap into an expansive ecosystem right from your wrist – with popular Google apps¹³ like Google Maps, and beloved Galaxy services¹⁴, like Samsung Pay, SmartThings and Bixby. The new platform also includes support for leading third-party apps¹⁵, like adidas Running, Calm, Strava, and Spotify available from Google Play. Along with our advanced hardware and even more intuitive user interface, you can enjoy smooth and convenient integrated experiences with your Galaxy Watch4. For example, our enhanced built-in compass works in tandem with Google Maps to make it easy to explore a new area.

 

Bringing Powerful Performance Directly to Your Wrist

This incredible experience is backed by serious hardware upgrades including the enhanced processor, richer displays, and expanded memory. Galaxy Watch4 series boasts the first 5nm processor in a Galaxy Watch – with 20% faster CPU and 50% more RAM, and a GPU 10 times faster than the previous generation. That means scrolling and multitasking on Galaxy Watch4 series is smooth and effortless. We also upped the resolution on the display, up to 450 x 450 pixels¹⁶, so visuals are crisper and more distinctive. And with an impressive 16GB of memory, you’ll have enough storage to download and store your favourite apps, music, and photos – with the confidence they’re secure, thanks to Samsung’s Knox security platform.

 

Samsung’ leadership in eSIM technology enables users to enjoy the freedom of being able to leave their phone behind, knowing their smartwatch will automatically sync up and fill the gap¹⁷. We also know a reliable battery is essential to smartwatch. You can have up to 40 hours¹⁸ of battery life, more than enough to keep a charge on an overnight camping trip – even as it supports the faster processor, higher resolution display, expanded memory and more sophisticated health features. And when you need more juice quickly, 30 minutes of charging provides up to 10 hours of battery.
