Apple is launching a brand-new Apple Watch along with three new iPhones today. The company just took the wraps off the new Apple Watch Series 4, the fourth iteration to the Apple Watch line.

Apple Watch Series 4 brings radical improvements to the Apple Watch line. It now includes a larger display, with a nearly edge-to-edge design that looks way more immersive than ever before. Apple says the displays are larger by up to 35%. The larger display means the device is slightly bigger as well, increasing by 2mm — so the Watch Series 4 is only available in 40mm and 44mm sizes, as opposed to the previous 38mm and 42mm sizes.

Under the hood, Apple has included a new S4 dual-core 64bit processor to offer up to 2x boost in performance. The company is even including a “next-gen” gyroscope that can detect when you fall. For people with heart problems, the company is introducing new features like getting notified when your heart rate is low and detect heart rhythm like atrial fibrillation, both powered by the optical sensor. There’s a new sensor that now lets you take an electrocardiogram, aka ECG, right with your Series 4 Watch which is certainly a big step forward for the Watch.

In other parts of the device, Apple says the crown on the Watch has been completely redesigned, and now gives you haptic feedback, so you will get a mechanical feel when you scroll or whenever you interact with the digital crown. The speakers inside the Watch has been redesigned to be louder, too, helping with watchOS 5’s new features like Walkie-Talkie. The company’s moved the microphone around to make your voice sound clearer to Siri and on calls as well.

With the bigger display on the Watch Series 4, Apple is tweaking the OS powering the product itself. First things first, with watchOS 5, the watch faces will now make better use of the larger display. The default watch face, for example, now displays more complications (read: widgets), than ever before. There are a bunch of new faces like the new Fire watchface, and Breathe watchface coming with the new Series 4 Watch. With the larger display, you will get more information at a glance, as long as your favorite watch face gets updated to make use of the bigger display. This applies to regular apps, like Maps, Music, etc.

Despite all the updates and new sensors, Apple has somehow managed to make the watch slightly slimmer compared to the previous generations. Although the watch bands for the Series 4 Watch will likely be slightly different from the previous generations, you should still be able to use your old watch bands with the new models. As for the battery life, Apple says the new Watch will continue to provide the same 18 hours of battery life as the Series 3, despite all the new upgrades.

Apple Watch Series 4 looks like a solid upgrade for the Apple Watch. The company’s even launching a wide variety of Sport Bands, Sport Loops, Modern Buckles, Hermés bands, and Milanese Loops, with a new Milanese band available in gold for the first time. The device will be available for $399, with the cellular model selling for $499. Apple’s reducing the price of the Series 3 Watch to $279, too.
