The Apple Watch Series 12 launched on Sept. 9 during Apple’s “Surprise and Shine” event, bringing a new Health Sensing System and faster charging speeds to the company’s flagship wearable lineup, according to a company press release. Apple’s Vice President of Worldwide iPhone Product Marketing Kaiann Drance called the device “the most advanced health and fitness companion we’ve ever created” in the announcement.
Apple Watch Series 12 Pricing and Model Lineup
The Apple Watch Series 12 starts at $399 for the 42mm aluminum case, matching the base price of the previous generation, according to hands-on reporting by Stan Schroeder for Mashable. However, the larger 46mm aluminum model costs $449, marking a $20 price increase over the Series 11. Titanium variants remain priced identically to their predecessors at $699 for the 42mm size and $749 for the 46mm version. Apple also introduced a new ceramic case option starting at $899 for the 42mm model and $949 for the 46mm model.
Design and Durability Updates
According to Mashable, the Series 12 retains the thin, lighter case design introduced with the Series 10. The wearable maintains IP6X dust resistance and water resistance up to 50 meters. For durability, Apple equipped the aluminum Series 12 models with Ceramic Shield 2 glass, which the company stated is 60 percent tougher than the Ion-X glass used on the Series 11.
Specs, Internal Memory, and Chipset
Powered by the new S11 chip, the Series 12 succeeds the S10 processor found in the Series 11. Citing Apple’s Xcode 27 developer tool, MacRumors reported that the Series 12 contains 4GB of RAM—double the 2GB of memory found in the Series 11. Storage capacity remains unchanged at 64GB.
Pro Tip: If you are upgrading from an older device, Apple introduced a range of new band colors and materials for the Series 12 starting at $49, which would also fit the Series 11, if you want to freshen up one you already own.
Battery Life and Charging Improvements
Both the Series 12 and Series 11 provide up to 24 hours of battery life on a standard charge, extending up to 38 hours when using Low Power Mode. The Series 12 improves on charging speed, delivering up to 12 hours of normal usage from a 15-minute charge, compared to eight hours for the Series 11.
Health Sensors and Exclusive Features
The Series 12 features a new Health Sensing System with upgraded optical and electrical sensors. According to Apple, the optical sensor measures heart rate every five seconds throughout the day and records heart rate variability (HRV) data up to 24 times more frequently than previous models. While both watches run watchOS and share core tools like Sleep Score, Hypertension and Sleep Apnea Notifications, and Fall Detection, the Series 12 adds exclusive audio intelligence tools—such as Sound Recognition alerts and Live Rewind transcriptions—alongside a revamped pedometer model for more accurate step tracking.
Did you know? The ceramic case option makes its return to the Apple Watch lineup with the Series 12, having previously appeared on much older models like the Series 2, 3, and 5.
