Watch Series 9 45 mm

This is the North American version of the Apple Watch Series 9 (GPS+Cellular, 45 mm), for the US, Canada, and Puerto Rico. The Series 9 is a refinement of the Series 8, featuring a new processor, a brighter display, a new "double tap gesture," and enhanced Siri functionality. This cellular model can operate independently online but needs an iPhone XS or later with iOS 17+. The 45 mm version has a 396x484 "Always-On Retina" LTPO OLED display with up to 2000 nits brightness (Ion-X glass for aluminum, sapphire crystal for steel). Battery life is rated for up to 18 hours, or 36 hours in Low Power Mode. Five aluminum and three stainless steel case options were available.

The North American Apple Watch Series 9 was widely praised as a comprehensive smartwatch solution that successfully balanced advanced technology with practical everyday functionality, making it suitable for both tech enthusiasts and casual users. The enhanced Siri performance was specifically noted to be significantly faster and more reliable than previous generations, with on-device processing eliminating many connectivity issues. The cellular functionality was consistently highlighted for its seamless carrier integration across major North American networks, providing users with genuine independence from their iPhones during activities like exercising or running errands. The device's health monitoring capabilities, particularly the sleep tracking and fall detection features, were appreciated by users across various age groups for their accuracy and potentially life-saving applications.
