Apple Watch Series 12

Apple's most advanced health companion yet. An all-new Health Sensing System pairs redesigned optical and electrical sensors with the S11 chip for higher-frequency heart monitoring and richer heart data — in an aluminum case that is brighter, tougher, and faster-charging than ever.

All-New Health Sensing System

Redesigned optical and electrical sensors work with the S11 chip to deliver higher-frequency background heart rate tracking, Recovery HRV, and richer heart data for more meaningful insights.

Health, Decoded

On-demand ECG, Blood Oxygen, irregular rhythm and high/low heart rate notifications, sleep apnea notifications, a nightly Sleep Score, and the Vitals app now tracking HRV — plus cycle tracking with improved period predictions and perimenopause support.

Tougher, Brighter Display

The Always-On Retina display uses wide-angle OLED (LTPO3) reaching up to 2000 nits. New Ceramic Shield 2 on the aluminum case is tougher than any smartwatch glass — 60 percent tougher than the Ion-X glass of previous aluminum models.

Faster Charging

Up to 24 hours of all-day battery (38 hours in Low Power Mode), 0–80% in about 30 minutes — and just 15 minutes on the charger now delivers up to 12 hours of use.

Frequently Asked Questions

GPS or GPS + Cellular — which should I get?

With GPS + Cellular and a wireless plan, your watch can take calls, send texts, stream music, and use 5G data with your iPhone left at home. The GPS model handles workouts, Precision L1 GPS route tracking, and everything else whenever your iPhone is nearby via Bluetooth or Wi-Fi.

What is new compared to Series 11?

The headline upgrades: an all-new Health Sensing System with higher-frequency heart monitoring and Recovery HRV, Ceramic Shield 2 on the aluminum case, Precision L1 GPS, Apple Intelligence with Siri AI on watchOS 27, and faster charging — 15 minutes now gives up to 12 hours of use.

42mm or 46mm?

Both sizes share every feature. 42mm suits slimmer wrists and is the lighter of the two; 46mm gives you a larger display for complications and easier reading at a glance.

Will my existing bands fit?

Yes — Apple kept the same band connector, so bands sized for your case (42mm or 46mm) from recent Apple Watch models carry straight over.

Is it genuine Apple?

Yes — 100% genuine Apple, supplied under official Apple part numbers (listed per configuration in the specifications), and covered by Apple's official 1-year limited warranty.
