Apple Watch Series 12 Titanium Case

The Apple Watch Series 12 Titanium Case pairs polished aerospace-grade titanium and a sapphire crystal display with the new Health Sensing System and the S11 chip.The Apple Watch Series 12 Titanium Case is built from polished aerospace-grade titanium and covered by a sapphire crystal display, which resists scratches better than the Ceramic Shield 2 used on the aluminium case. It weighs 36.5 grams at 42mm and 44.9 grams at 46mm, sitting between aluminium and ceramic, and it comes with GPS + Cellular as standard rather than as an upgrade. Inside, it is the same watch as the other finishes: 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, plus 5G and LTE. 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 Titanium Case Key Features: Polished aerospace-grade titanium - a harder, more scratch-resistant case than aluminium, with a polished rather than matte finish. Sapphire crystal display - more scratch resistant than the Ceramic Shield 2 fitted to the aluminium case, which is the main practical reason to pay more for titanium. GPS + Cellular as standard - 5G and LTE are built in, so the watch stays connected with the iPhone left at home. Two colours - Natural and Radiant Gold, chosen from the product options. 36.5 grams at 42mm and 44.9 grams at 46mm - heavier than aluminium and lighter than ceramic. 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. 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.
