🕒 Last Updated on September 7, 2025, 1:44 PM IST

Ahead of the September 9 “Awe-Dropping” event, rumors suggest the Apple Watch Series 11 will boast a brighter screen, new colors, and AI workout tools, while the rugged Ultra 3 may offer satellite SOS, extended battery, and even blood pressure detection.

Series 11: Familiar Look, Smarter Features

Design-wise, the Apple Watch Series 11 is expected to closely resemble its predecessor—but with key upgrades. A brighter display will improve outdoor visibility, and new color options and straps should refresh the appeal. It’s powered by the new S11 chip, boosting efficiency and performance while running watchOS 26. New features like AI-based workout coaching and a refined Health app could make it the most intuitive Watch yet. Blood-pressure alerts might be included, though deep regulatory work remains.

Ultra 3: Powerhouse Upgrades for Outdoor Lovers

The Apple Watch Ultra 3 is shaping up to be a rugged powerhouse. It reportedly features a larger OLED display with slimmer bezels and could include satellite-based SOS, 5G RedCap support, and a thicker battery promising more than 36 hours of usage. Performance-wise, it’s believed to run on the S11 chip as well, possibly with a higher-resolution display and enhanced charging. High blood pressure monitoring may arrive here first, though precision remains uncertain.
