Watch Series 4 40 mm

This A2007 Apple Watch Series 4 Nike+ (GPS+Cellular, 40 mm) is the global version, for use on LTE/UMTS networks outside North America. It combines the larger display and advanced sensors of the Series 4—including fall detection and ECG—with exclusive Nike features. This cellular model can connect online independently but requires an iPhone 6 or later with iOS 12+. The device has a 324x394 LTPO OLED screen with Ion-X glass, an aluminum case, and a ceramic/sapphire crystal back. It includes unique Nike watch faces and the integrated Nike+ Run Club app. Battery life is estimated at up to 18 hours. Four configurations were offered, pairing silver or Space Gray aluminum cases with a Nike Sport Band or Sport Loop.

The Series 4 earned recognition as the first truly massive upgrade, delivering exceptional accuracy with its larger display and second-generation optical heart rate sensor. The Nike+ edition featured innovative reflective threads in Sport Loops for enhanced nighttime visibility, while exclusive watch faces seamlessly integrated fitness functionality. GPS precision frequently outperformed premium sports watches from competitors, with heart rate accuracy establishing new industry benchmarks for wrist-based optical sensors.
