All Apple Watch Models
Please note that this Apple Watch Series 9 (GPS+Cellular, United States/Canada, 45 mm) model is compatible with LTE bands 1, 2, 3, 4, 5, 6, 7, 12, 13, 14, 17, 18, 19, 25, 26, 39, 40, 41, and 66 as well as UMTS 2100 MHz, 1900 MHz, 1700/2100 MHz and 850 MHz. It is not compatible with LTE bands 8 (900 MHz), 20 (800 DD), or 28 (700 APT MHz) or with UMTS 900 MHz. It is sold in the United States, Canada, and Puerto Rico.
The Apple Watch Series 9 models are quite similar to the Apple Watch Series 8 models that they replaced, but they have a new processor, a brighter display, support for a "magical new double tap gesture," and improved Siri capabilities.
All cellular-equipped Apple Watch Series 9 models, including this one, are capable of being connected to the Internet without a "tethered" iPhone, but it still is intended to be used with an iPhone XS or later running iOS 17 or later for some functions.
All Apple Watch Series 9 devices are controlled with a Digital Crown with haptic feedback and a touch capable display. This particular Apple Watch Series 9, the Cellular-capable model in the 45 mm size, features a 396x484 "Always-On Retina" LTPO OLED screen with "up to" 2000 nits of brightness and has either Ion-X glass packed in an aluminum case or sapphire crystal glass packed in a stainless steel case as well as a ceramic and sapphire crystal back that connects to the charger.
Battery life is an Apple estimated "up to 18 hours" overall in modest use; the "Low Power Mode" option can extend battery life to up to 36 hours by disabling the Always-On Display and other functions.
There are five aluminum body options that were offered by Apple Authorized Resellers -- pink, nearly black "Midnight", warm gray "Starlight" (pictured, left), silver, and (PRODUCT) RED -- as well as three stainless steel options -- gold, silver, and graphite (pictured, right). A variety of bundled bands in addition to a wide range of additional watch bands were available from Apple via customization, as well.
