Apple Watch Series 12 (GPS + Cellular) 42mm Natural Titanium Case with Natural Milanese Loop

The new Apple Watch Series 12 (Titanium case, 42 mm) puts the all-new Health Sensing System in a polished titanium case with a sapphire front crystal. Redesigned optical and electrical sensors read your heart rate every five seconds all day and measure heart rate variability up to 24 times more often than before, and every morning a Readiness score tells you how much your body has to give, adjusting as your day unfolds. Every titanium model comes with cellular built in.

Series 12 is made for every kind of training, from running and cycling to swimming, yoga and HIIT. Workout Buddy, powered by Apple Intelligence, now works even when your iPhone is nowhere nearby, giving you spoken, personalised encouragement based on your heart rate, pace and progress. Activity rings, trends and awards keep the everyday motivation going, and up to 10 hours of outdoor workout tracking covers the long sessions.

Titanium gives Series 12 a harder, more scratch-resistant finish than aluminium, protected by a sapphire crystal front, in a case that still weighs only 36.5 grams. This is the thinnest Apple Watch ever made, and the wide-angle always-on Retina display reaches 2,000 nits in bright sun and dims to a single nit at night. Battery life runs to 24 hours of normal use, 15 minutes on the charger adds up to 12 hours, and water resistance to 50 metres means pool lengths and open water are both fair game.

watchOS 27 brings Siri AI, with broad world knowledge and an understanding of your personal context, along with Audio Intelligence features such as Live Rewind and Siri Recap. A dynamic app grid surfaces the apps you actually need, and a single-handed tap gesture moves you through the Smart Stack. With 5G and LTE built in, you can leave your iPhone behind and still take calls, stream music and use Apple Pay.
