Apple Launches Apple Watch Series 12 and Ultra 4 With Advanced Health Tracking

Apple says the aluminum Series 12 models’ Ceramic Shield 2 glass is 60% tougher than the Ion-X glass used on the previous generation, adding durability without significantly changing the watch’s design.
The Series 12 lineup includes additional premium configurations not detailed in the summary: titanium models start at $699, ceramic models start at $899, and Hermès versions range from $1,399 for the Series 12 to $1,499 for the Ultra 4.
Apple has substantially refreshed the accessory range, including new Sport Band, Sport Loop, Milanese Loop, Link Bracelet, Modern Buckle and Solo Loop colors; the Ultra 4 also receives new Trail, Alpine and translucent Ocean Band options.
The watch’s battery improvements include up to 10 hours of outdoor workout use, compared with the stated 24-hour everyday rating, and Apple says a 15-minute charge can provide up to 12 additional hours of battery life.
Apple is also planning a redesigned Health app with an Insights tab powered by Apple intelligence, extending the new health and recovery tools beyond the watch itself.
Apple has launched the Apple Watch Series 12 and Ultra 4, focusing on health monitoring and on-device artificial intelligence rather than a major design overhaul. Geeky Gadgets reports the Series 12 starts at $399 and arrives September 18, while the Ultra 4 begins at $799. The new Health Sensing System and S11 chip enable heart-rate readings every five seconds and a 0-to-10 Readiness score that tells users whether to recover or train.
New Audio Intelligence features include Sound Recognition and Live Rewind, which can transcribe the previous 15 seconds of conversation. Dataconomy reports Apple processes all audio locally on the device and does not store recordings. Aluminum models now include Ceramic Shield 2 glass, which Gizmodo says is 60% tougher than the previous generation's Ion-X glass, adding durability without changing the watch's thin design.
The Series 12 measures heart rate every five seconds instead of the previous intervals, and adds separate recovery and overall heart-rate variability metrics. Geeky Gadgets notes the watch now captures more daytime and overnight vital signs. The new Readiness score analyzes this data to suggest whether users should rest or push harder in training. Apple also improved step and distance tracking with the upgraded sensor system.
These updates position the watch as a continuous health platform rather than just a fashion accessory. Users can now get granular recovery insights without wearing a separate tracking ring or armband. The Health Sensing System combines expanded electrodes for ECG readings with redesigned photodiodes to boost optical clarity. A redesigned iPhone Health app with an Insights tab will extend these tools beyond the watch itself.
Apple added three new audio features: Sound Recognition listens for specific noises, Live Rewind transcribes the last 15 seconds of conversation, and Siri Recap summarizes recent audio. Dataconomy reports the watch also speeds up Shazam song identification. Apple emphasized that audio processing happens on the device itself in a hardware-isolated Secure Exclave within the S11 chip.
The company states raw audio is "processed in complete isolation from the rest of the system and immediately deleted." No recordings are stored or sent to Apple's servers. This local processing reduces exposure of sensitive conversations compared to cloud-based systems, though users still need to grant microphone access and monitor nearby speech being analyzed on the device.
The Series 12 lineup now spans five material options, each at a different price point. Noypi Geeks reports the aluminum model starts at $399, while titanium models begin at $699 and ceramic models start at $899. Hermès editions range from $1,399 for the Series 12 to $1,499 for the Ultra 4. This segmentation lets Apple capture customers at multiple price points without redesigning the core watch.
Apple also refreshed its band lineup with new Sport Bands, Sport Loops, Milanese Loops, Link Bracelets, and Solo Loops in additional colors. The Ultra 4 receives new Trail, Alpine, and translucent Ocean Band options. Bands range from $49 to $349, creating recurring accessory revenue. This strategy encourages personalization and later purchases while deepening ecosystem lock-in.
The Series 12 delivers up to 24 hours of everyday battery life, matching the previous generation's endurance. For outdoor workouts using GPS, Apple guarantees 10 hours of continuous use. A 15-minute quick charge supplies up to 12 additional hours of battery life. The aluminum models gain Ceramic Shield 2 glass, which Gizmodo states is 60% more durable than Ion-X, improving everyday protection without adding bulk.
In the Philippines, Noypi Geeks reports Smart Communications offers the Apple Watch Series 12 through Smart Postpaid Plans starting at Plan 999. Smart Device Link costs ₱199 per month with a six-month trial for new users through September 30. The carrier also bundles the SE 3, Series 11, and Ultra 3 models. Availability begins September 18 globally and through local carriers in select markets.
