The Apple Watch Series 4 is a smartwatch developed by Apple Inc. It was announced on September 12, 2018, alongside the iPhone XS and iPhone XS Max. It is the fourth generation of the Apple Watch, succeeding the Apple Watch Series 3.
The Series 4 features a new design with a larger display, slimmer body, and new user interface. It has a 30% larger screen compared to its predecessor, with a resolution of 448 x 368 pixels. The screen is also curved at the edges, which allows for a more seamless integration with the watch body. The body of the Series 4 is also slimmer than previous models, making it more comfortable to wear.
The Series 4 also has a new user interface, with a redesigned dock, new complications, and a new control center. The dock allows users to access their favorite apps quickly, while the complications provide quick access to important information. The control center has also been redesigned, with a new layout and easier access to important features.
In terms of functionality, the Series 4 has a number of new features, including a built-in electrocardiogram (ECG) monitor and fall detection. The ECG monitor allows users to take an ECG reading by placing their finger on the digital crown, while the fall detection feature can automatically send an alert if it detects a fall.
The Series 4 is available in two sizes: 40mm and 44mm. It is available in three finishes: aluminum, stainless steel, and ceramic. It is also available in a number of different bands, including sport bands, leather bands, and metal bands.
