Apple Watch Series 4

In addition to the iPhone XS and iPhone XS Max announcement in September, Apple announced the new Apple Watch Series 4. This is the biggest change in the watch so far, with a new design that allows the screen to curve along the edges of the face. This means the size of the screen has increased from a 38mm and 42mm display, to 40mm and 44mm. The physical size of the casing, however, remains similar to the previous iterations, so all of your existing watch bands will be compatible with the new version. Apple is taking advantage of the extra screen real estate to debut a brand new watch face: Infograph. This puts more complications on the face of the Apple Watch than ever before in a more circular layout.

Apple Watch Series 4 has also made great strides with heart tracking. Coming later this year, It will notify you of irregularities, and if your heart rate is too fast or too slow. It also will be able to take an electrocardiogram or ECG right from the watch. The new Digital Crown contains an electrode that reads the electrical heart impulses in your fingertip, and the back has a chromium silicon carbon nitride layer that can read the electrical heart impulses in your wrist. The ECG readings will automatically be stored in the Health app on the iPhone.

Apple Watch Series 4 has a new accelerometer and gyroscope that can detect falls. If you've fallen, it will give you a "hard fall alert" and you can easily initiate a call to emergency services or dismiss it. If you're unresponsive after 60 seconds, the emergency call is automatically placed and a message with your location will be sent to emergency contacts.

Apple Watch Series 4 starts at $399 for the aluminum GPS model, and $499 for the aluminum GPS + Cellular model. It's available in silver, space gray, and gold.
