Apple Watch Series 12 Aluminum Case with Sport Band

The Apple Watch Series 12 Aluminum Case pairs a matte aluminium finish and Ceramic Shield 2 with the new Health Sensing System, the S11 chip and an Always-On Retina display at 2000 nits.The Apple Watch Series 12 Aluminum Case is the lightest of the three Series 12 finishes and the only one you can buy with GPS only as well as GPS + Cellular. The case has a matte finish and the display is protected by Ceramic Shield 2 rather than sapphire crystal. At 42mm it weighs 32.2 grams on GPS and 31.5 grams on GPS + Cellular; at 46mm it weighs 39.5 and 38.6 grams. Inside, it is the same watch as the titanium and ceramic models: a new Health Sensing System paired with the S11 chip, Apple's most powerful wearable chip, with a 64-bit dual-core processor, a 4-core Neural Engine and 64GB of storage.The Health Sensing System measures heart rate and heart rate variability more frequently than before, which Apple describes as the most accurate heart rate sensing it has put in a wearable, and it feeds a new readiness score that tells you whether to push or take it easy. The Always-On Retina display uses wide-angle OLEDs with LTPO3 and drops to a 1Hz refresh rate to save power. It reaches 2000 nits at peak and dims to a single nit in the dark, running at 374 x 446 on the 42mm case and 416 x 496 on the 46mm, both at 326 pixels per inch.Health tracking covers the ECG app, the Blood Oxygen app, an always-on optical heart sensor, a temperature sensor, irregular rhythm and hypertension notifications, Advanced Cycle Tracking, the Vitals and Medications apps, and a Sleep app with sleep stages, a sleep score and sleep apnea notifications. Safety features include Fall Detection, Crash Detection and Emergency SOS. The case is water resistant to 50 metres under ISO 22810:2010 with an IP6X dust rating and a depth gauge good for 6 metres.Battery life runs to 24 hours of normal use, 38 hours in Low Power Mode and 10 hours of outdoor workout tracking, with fast charging reaching 80% in about 30 minutes. Connectivity covers precision L1 GPS across GPS, GLONASS, Galileo, QZSS and BeiDou, Wi-Fi, Bluetooth 5.3, a second-generation Ultra Wideband chip, Apple Pay and GymKit, with 5G and LTE on the GPS + Cellular models. It runs watchOS 27 with Siri powered by Apple Intelligence, and pairs with an iPhone 11 or later on iOS 27 or later.Apple Watch Series 12 Aluminum Case Key Features: Matte aluminium case with Ceramic Shield 2 - the lightest Series 12 finish, from 31.5 grams at 42mm, with the display protected by Ceramic Shield 2.

Four colours - Dark Bronze, Light Gold, Black and Space Gray, chosen from the product options. All-new Health Sensing System - the most accurate heart rate sensing Apple has put in a wearable, with higher-frequency heart rate and heart rate variability measurements. Readiness score - a single daily number built from your sleep, heart data and recent activity, so you know whether to train hard or hold back. S11 chip with a 4-core Neural Engine - Apple's most powerful wearable chip, with 64GB of storage on board. Always-On Retina display at up to 2000 nits - wide-angle OLED with LTPO3, dropping to 1Hz to save power and to 1 nit in the dark. Two case sizes, 42mm and 46mm - 374 x 446 and 416 x 496 respectively, both at 326 pixels per inch. ECG app and Blood Oxygen app - alongside irregular rhythm notifications, hypertension notifications and the Vitals app. Sleep stages, a sleep score and sleep apnea notifications - a full picture of the night rather than a simple hours count. 50 metre water resistance and IP6X dust resistance - swimproof under ISO 22810:2010, with a depth gauge and a water temperature sensor. Up to 24 hours of normal use and 38 hours in Low Power Mode - with fast charging to 80% in about 30 minutes. watchOS 27 with Siri powered by Apple Intelligence - personal context and world knowledge answered from the wrist.
