Not just evolved, transformed.
The largest Apple Watch display yet. New electrical heart sensor. Re-engineered Digital Crown with haptic feedback. Entirely familiar, yet completely new, Apple Watch Series 4 resets the standard for what a watch can be. Series 4 represents a fundamental redesign and re‑engineering of Apple Watch. From the curved corners of the larger, all‑new display to the architecture of the S4 chip, every detail has been thoughtfully considered. Apple Watch has always been a uniquely personal product. And now it’s even more powerful.
The largest Apple Watch display yet. This is huge.
The display is the defining feature of Apple Watch, and Series 4 pushes it further than ever. The challenge was to make it bigger without noticeably increasing the size of the case or compromising the battery life. Narrower borders enable a viewing area that’s over 30% larger, while a new display technology called LTPO improves power efficiency, helping you get through the day on a single charge.
A better experience all the way around.
Curved corners precisely match the radius of the case, creating a more pleasing, continuous appearance. This also allows imagery and the touch surface to extend to the farthest reaches of the screen.
More information in every millimeter.
To take full advantage of the new dimensions of the display, the entire interface has been redesigned to provide more information with richer detail. The new Infograph watch face can accommodate up to eight complications, so you can see more and do more at a glance.
Proactive Health Monitor
Part guardian, part guru.
ECG on your wrist. Low and high heart rate notifications. Fall detection and Emergency SOS. New Breathe watch faces. It’s designed to improve your health every day and powerful enough to help protect it.
Two sensors. A pair of eyes on your heart.
The optical heart sensor has been part of Apple Watch from the beginning, allowing you to quickly check your heart rate. Thanks to a new electrical heart sensor (made up of an electrode in the Digital Crown and electrodes on the back crystal), you can use the ECG app to generate an ECG, or electrocardiogram, at any time to share with your doctor.
All-new S4 chip. The S4 is more than just a processor. It’s a complete Silicon in Package (SiP), with the entire system fabricated onto a single component. This architecture allows Apple Watch to pack amazing capabilities into a tiny space. In fact, Apple Watch is the only product in the world that runs completely on a SiP. Up to 2x faster. This fourth-generation CPU is faster than ever. Apps open more quickly and performance is boosted across the entire system. 50 percent louder speaker. Bigger and even more powerful, the Apple Watch Series 4 speaker provides dramatically improved audio quality for Siri and Walkie‑Talkie. In addition, the microphone has been relocated to the opposite side to reduce echo for clearer phone calls.
