Please note that this A2375 Apple Watch Series 6 (Nike GPS+Cellular, Global, 40 mm) model is compatible with LTE bands 1, 2, 3, 4, 5, 7, 8, 18, 19, 20, 25, 26, 28, 39, 40, 41, and 66 as well as UMTS 2100 MHz, 1900 MHz, 1700/2100 MHz, 850 MHz, and 900 MHz. It is not compatible with LTE bands 12 (700 MHz), 13 (700c MHZ), or 17 (700b MHz). It is sold globally (just about everywhere in the world except for the United States, Canada, Mexico, and Puerto Rico).

The Apple Watch Series 6 models look nearly identical to the Apple Watch Series 5 that they replaced, but they have a faster architecture, and add an "always-on" altimeter and a Blood Oxygen sensor (SpO2). They also offer a variety of new finishes and watch band options.

All cellular-equipped Apple Watch Series 6 models, including this one, are capable of being connected to the Internet without a "tethered" iPhone, but it still requires an iPhone 6s or later running iOS 14 or later for most functionality.

All Apple Watch Series 6 devices are controlled with a Digital Crown with haptic feedback and a touch capable display. This particular Apple Watch Series 6, the Global cellular-equipped Nike model in the 40 mm size, features a 324x394 LTPO OLED screen with Ion-X glass packed in an aluminum case with a ceramic and sapphire crystal back that connects to the charger.

Battery life is an Apple estimated "up to 18 hours" overall, but more specifically "up to 1.5 hours" of talk time connected to an iPhone (or to LTE), "up to 11 hours" of audio playback from Apple Watch storage, "up to 11 hours" working out indoors and "up to 7 hours" working out outdoors with GPS.

There are at least two aluminum options for this model available from Apple Authorized Resellers -- Space Gray with an Anthracite/Black Nike Sport Band and Silver with a Pure Platinum/Black Nike Sport Band (pictured, left). Numerous other body and watch band combinations are available from Apple via customization, as well.
