New biometric sensors measure recovery vitals every five seconds

The Takeaway

• The Apple Watch Series 12 revives an exclusive ceramic case edition finished in classic pearl white and night blue.
• Operating system upgrades to watchOS 27 arrive for previous hardware generations starting on Monday, September 14 across all eligible international regions.
• An on-device Live Rewind tool transcribes the final fifteen seconds of a spoken conversation.
• Users in the US can purchase optional routine lab panels featuring over fifty biomarkers for $119 through Quest Diagnostics.

Apple equips its newest smartwatches with an upgraded S11 processor built on the same core CPU and GPU architecture as the A20 Pro. Dedicated audio hardware processes data locally. The Series 12 offers aluminium bodies in dark bronze, black, light gold, or space gray. Shoppers can also select titanium cases in radiant gold and natural. Both metal variants come in 42mm and 46mm case sizes. For rugged outdoor demands, the Ultra 4 arrives in natural and black titanium, paired with an optional Hermès Grand H band. Battery refills speed up significantly on the base model, where a quick 15-minute charge supplies 12 hours of operational use.

The underlying Health Sensing System creates the genuine functional difference here. Upgraded green LEDs and broader electrodes capture pulse rates every five seconds throughout the day. Heart rate variability logs every five minutes to evaluate daily physical strain through Recovery HRV and overall HRV. That continuous telemetry powers a daily Readiness score from zero to ten, directing you to Recover, Pace Yourself, Ready, or Go For It. Furthermore, the accompanying Health app uses an iPhone camera to conduct on-device Movement Evaluations for physical balance and joint mobility without recording private video.

Apple Watch Series 12 and Ultra 4 specifications

Indian retail channels will carry both smartwatches alongside the wider international rollout. Shoppers looking for alternative straps can choose the new Apple Watch band designed to handle Indian heat, priced at Rs 4,500 with an 11-colour weave. On the software side, the Health app update brings menopause tracking and post-menopause bleeding notifications. Surprisingly, logged pattern deviations can flag perimenopause years before a final cycle occurs. Domestic buyers should remember that the on-device Audio Intelligence tools require an iPhone 16 or newer, and European Union regulations block those specific features initially.

The Unboxed Truth

Unbox Daily HQ rates the Apple Watch Series 12 as a worthwhile purchase if you want clinical-grade cardiovascular recovery telemetry on your wrist. The camera-driven mobility screenings let you track physical balance at home rather than booking clinic appointments. The confirmed Rs 56,900 entry price for the base model, rising to Rs 1,09,900 for the Ultra 4, matches the cost of a discounted iPhone 13 or a large smart television. That hardware lock is a genuine pain for anyone holding an older handset. You will also wait until later in the year for the redesigned Health app to arrive.

Best for: Athletes and fitness enthusiasts monitoring cardiovascular recovery.

Who Is This For: Health-conscious buyers aged 25 to 45.
