Apple on Wednesday introduced a brand-new version of its best-selling smartwatch: the Apple Watch Series 4.
The new watch has new features like the ability to measure your heart rate with an electrocardiogram, and a hardware redesign that gives it a larger display.
The Apple Watch Series 4 will come in two versions — aluminum and stainless steel — and will come in gold, silver, and space gray. The watch will start at $399.
Here’s a rundown of the specs:
-A nearly edge-to-edge display — the screen is now 30% larger than previous versions.
-New watch faces, including one with up to eight customizable complications, or special features
-The digital crown now has haptic feedback
-The speaker is 50% louder, which means it’s better for making phone calls and using Siri
-The back is now made from ceramic and crystal, which means radio waves can pass through the front and back for better cellular reception
-A new S4 chip
-A faster, 64-bit processor
-A new accelerometer and gyroscope that let the watch detect falls
-New heart rate tracking, including a new low heart rate notification and atrial fibrillation detection
-Built-in sensors that let you take an electrocardiogram, or ECG. Apple says it has received clearance from the FDA for its heart rate tracking features
-Like the Apple Watch Series 3, it will be swimproof and have built-in GPS
18 hours of battery life
-It will run WatchOS 5, Apple’s new smartwatch operating system
The Apple Watch Series 4 will go on sale on September 14 and will be available September 21. Watch OS 5 will be available on September 17.
