Apple Watch Series 4 40mm black/red

The Apple Watch Series 4 is the fourth generation of Apple's popular smartwatch lineup, and it comes in a sleek black and red colorway.
The watch has a 40mm case, which is a great size for those with smaller wrists or who prefer a more compact watch. It's also available in a larger 44mm size for those who want a bigger display.
The watch features an all-new display that is over 30% larger than previous models, but the overall size of the watch is only slightly bigger thanks to reduced bezels. The result is a larger and easier-to-read screen that doesn't feel bulky on the wrist.
The Series 4 watch includes a host of new health features, including an ECG app that can detect irregular heart rhythms, fall detection that can alert emergency services if you take a hard fall, and a new activity tracking feature that allows you to compete against friends and family.
The watch also has built-in GPS and cellular connectivity, allowing you to track your workouts without needing to bring your phone along. With cellular, you can make and receive calls, send texts, and stream music even when your phone is not nearby.
The Series 4 watch includes a number of new watch faces, including ones that can display up to eight complications (i.e. widgets) at once, giving you quick access to important information like the weather, your calendar, and your fitness stats.
The watch is powered by Apple's new S4 chip, which provides faster performance and improved efficiency. This means you can expect a snappier experience overall, with apps launching more quickly and smoother animations.
The watch runs watchOS 5, which includes a host of new features like Walkie-Talkie, which allows you to send quick voice messages to other Apple Watch users, and Siri Shortcuts, which lets you automate tasks and control your smart home devices using your voice.
The watch is compatible with a wide range of third-party apps, allowing you to customize your experience to your liking. From fitness apps to productivity apps to social media apps, there's something for everyone on the App Store.
Overall, the Apple Watch Series 4 is a fantastic smartwatch that's packed with features and functionality. Whether you're a fitness enthusiast, a tech lover, or just someone who wants to stay connected on the go, the Series 4 is definitely worth considering.
