The Apple Watch Series 4 models look similar to earlier models, but have larger displays, more advanced input capabilities, more powerful internals, and more advanced sensors (most notably a new accelerometer and gyroscope that can detect falls and an electrical heart sensor)..

All cellular-capable Apple Watch Series 4 models, like this one, are capable of being connected to the Internet without a "tethered" iPhone, but it still requires an iPhone 6 or newer running iOS 12 or later for most functionality.

All Apple Watch Series 4 devices are controlled with a Digital Crown with haptic feedback and a Force Touch capable display. This particular Apple Watch Series 4, the Nike+ Cellular+GPS model in the 44 mm size, features a 368x448 LTPO OLED screen with "strengthened, lightweight Ion-X glass" packed in a 7000 series anodized aluminum housing with an "all ceramic and sapphire crystal back" that connects to the charger.

All Apple Watch Series 4 Nike+ models include unique Nike watch faces, a built-in Nike+ Run Club app, and "a new Audio Guided Run every week with the voice of a guest coach."
