The Apple Watch Series 4 gets a new dial, which can be expanded with eight complications and then displays a lot of additional information. In addition to the analog clock, Apple also places advertisements for the weather, upcoming appointments and the timer. Dynamic dials simulate elements such as fire, water or steam.
The Apple Watch Series 4 can detect a fall and – if you do not respond after a minute – automatically start an emergency call.
With an electric heart sensor, the new Apple Watch measures the heart rate and warns if it is too low. Cardiac arrhythmias can also detect the clock and immediately alert those affected. While the current series only measure heart rate, Series 4 models also support electrocardiography. Open the app and place your finger on the digital crown. The electrodes on the back of the watch measure electrical impulses from the heartbeat and send it to the S4 chip. After 30 seconds, users receive their heart rate analysis.
