Apple Watch Series 12 and Ultra 4 Hit Retailers

The flagship Apple Watch Series 12 starts at $399, available in 42mm and 46mm sizes with a variety of aluminum, titanium, and ceramic finishes. For those requiring rugged performance, the Apple Watch Ultra 4 is positioned at $799, offering a 49mm titanium case and standard cellular connectivity. Retail availability spans major outlets including the Apple Store, Amazon, Best Buy, and Walmart.

Performance gains are driven by the new S11 chip, which powers a refined Health Sensing System. This hardware provides continuous heart rate monitoring and a new Readiness score designed to calibrate exercise intensity. Additionally, the chip facilitates on-device Audio Intelligence, enabling features like Sound Recognition and Live Rewind transcriptions without compromising user privacy. Battery life remains a key differentiator: the Series 12 offers 24 hours of use, while the Ultra 4 delivers 50 hours, extending to 84 hours in low-power mode.
