Apple Watch Series 12 at LEVIT online store

Apple Watch Series 12 brings one of the biggest health sensing upgrades to Apple Watch in recent years. The new Health Sensing System combines redesigned optical and electrical heart sensors, more frequent heart rate and HRV measurements and the new Readiness score for a clearer view of daily recovery.

At LEVIT, Apple Watch Series 12 is available in 42mm and 46mm sizes, with GPS and GPS + Cellular configurations and a choice of aluminum, titanium or ceramic cases.

The new Health Sensing System

Apple redesigned the sensors on the back of Series 12. Larger and more power-efficient green LEDs allow the optical sensor to measure heart rate every five seconds throughout the day.

Apple describes the new system as delivering the most accurate heart rate sensing in a wearable based on its study. More frequent readings also improve activity and fitness measurements and provide additional information about recovery.

Readiness Score

The new Readiness experience is designed to show whether the body appears ready for a demanding day or may benefit from more recovery. It turns several health and recovery measurements into an easier daily indicator instead of leaving users to interpret every metric separately.

More frequent HRV measurements

Series 12 measures heart rate variability more frequently and introduces Recovery HRV. HRV also becomes part of the Vitals overview alongside heart rate, respiratory rate, wrist temperature, sleep and other supported measurements.

Heart and sleep features

Apple Watch Series 12 supports the ECG app, high and low heart rate notifications, irregular rhythm notifications, Sleep Score, sleep stage tracking and sleep apnea notifications. Blood Oxygen, wrist temperature sensing, Advanced Cycle Tracking and hypertension notifications are also available where supported. Individual health features can vary by country or region.

Apple S11 chip

The new S11 uses a 64-bit dual-core processor and a 4-core Neural Engine. Apple Watch Series 12 includes 64GB of storage.

S11 also powers the new Apple Intelligence, Siri AI and Audio Intelligence experiences, giving the watch more capability without depending on the iPhone for every interaction.

Siri AI and Audio Intelligence

With watchOS 27, Siri AI brings more personal and contextual assistance to Apple Watch. Audio Intelligence adds features including Live Rewind, Siri Recap, Shazam and Sound Recognition. Some Audio Intelligence features are scheduled to arrive later in 2026 and availability can vary by language and region.

42mm and 46mm sizes

Series 12 comes in 42mm and 46mm case sizes. The wide-angle Always-On Retina display uses LTPO3 OLED technology and can refresh as low as 1Hz.

The 42mm version has a 374 x 446 pixel active area, while the 46mm model uses 416 x 496 pixels. Peak brightness reaches 2,000 nits and minimum brightness can drop to 1 nit.

Aluminum, titanium and ceramic

Aluminum finishes include Dark Bronze, Light Gold, Black and Space Gray. Titanium is offered in Radiant Gold and Natural. Series 12 also brings ceramic cases in Pearl White and Night Blue, both with sapphire front crystals.

Ceramic Shield 2

Aluminum Series 12 models now use Ceramic Shield 2. Apple says it is 60% tougher than Ion-X, improving protection for a device that spends most of its life exposed on the wrist. Titanium and ceramic versions use sapphire front crystals.

Up to 24 hours of battery life

Apple rates Series 12 for up to 24 hours of normal use and up to 38 hours in Low Power Mode. Outdoor workout battery life reaches up to 10 hours.

Fast charging can reach around 80% in approximately 30 minutes. A 15-minute charge provides up to 12 hours of normal use, while five minutes can provide up to 10 hours of sleep tracking.

Built for swimming and workouts

Apple Watch Series 12 is rated WR 50M and IP6X for water and dust resistance. It includes a depth gauge rated to 6 meters and a water temperature sensor.

Workout features cover running, cycling, swimming, hiking, strength training and many other activities, with metrics such as heart rate zones, Training Load, pace, distance and elevation.

Safety features

Emergency SOS, Fall Detection, Crash Detection, Check In and international emergency calling remain part of the Series 12 safety package in supported regions.

GPS and GPS + Cellular

Series 12 is available in GPS and GPS + Cellular configurations. Supported Cellular models add 5G RedCap alongside LTE, allowing more independent connectivity when carrier support is available.

What is actually new in Series 12?

The biggest Series 12 changes are focused on health sensing rather than a dramatic visual redesign. More frequent heart rate and HRV measurements, Readiness Score, the new Health Sensing System, S11 and the new intelligent features make it a more capable fitness and health companion.

Battery life of up to 24 hours, Ceramic Shield 2 on aluminum models and the return of premium ceramic cases add practical improvements around the new sensing hardware.
