Apple Watch Series 4 40mm GPS NIKE+ Aluminum Space Grey/Black Band

All new. For a better you.
Introducing Apple Watch Series 4. Fundamentally redesigned and re-engineered to help you stay even more active, healthy, and connected.

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.



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.

Digital Crown. A breakthrough reborn.
The Digital Crown was invented to provide an easy way to navigate on Apple Watch without obstructing the display. With Apple Watch Series 4, the mechanism has been totally re‑engineered. Haptic feedback now delivers a precise, click-like feel as you scroll. And a titanium electrode built into the top allows you to use the ECG app simply by touching it with your finger.
ECG app coming later this year.



A miracle of miniaturization.
Already one of the most intricate systems Apple has created, the Digital Crown on Apple Watch Series 4 adds even more capability into significantly less space. The entire assembly is 30 percent smaller, yet it includes 21 percent more components.

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.

The biggest thinking happens in the smallest spaces.
Optimized in every way, the new Apple Watch is more powerful, yet even thinner than before. And it delivers up to 18 hours of battery life on a single charge.




All-new S4 chip. The S4 is more than just a processor. It’s a complete System 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.2 Apps open more quickly and performance is boosted across the entire system.

50 percent louder speaker. Larger and even more powerful, the Apple Watch Series 4 speaker provides dramatically bigger sound for Siri and Walkie‑Talkie. In addition, the microphone has been relocated to the opposite side to reduce echoes for clearer phone calls.



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.
ECG app coming later this year.
