Watch Series 4 40 mm

The Apple Watch Series 4 featured a significant redesign, and this Nike+ version integrates those advancements with exclusive Nike branding. This specific model (GPS, 40 mm) lacks cellular capability and requires an iPhone 5s or later with iOS 12+ for most features. It has a larger display, more powerful internals, and advanced sensors for fall detection and ECG. The 40 mm Nike+ GPS model features a 324x394 LTPO OLED screen with Ion-X glass, an aluminum case, and a ceramic/sapphire crystal back. All Nike+ models include unique watch faces and the Nike+ Run Club app. Battery life is rated for up to 18 hours. Four configurations were available, pairing silver or Space Gray aluminum cases with a choice of Nike Sport Band or Sport Loop.
