Apple Watch Series 12 (GPS + Cellular) 42mm Black Aluminium Case with Black Sport Band, M/L

The new Apple Watch Series 12 (Aluminium case, 42 mm) is built around the all-new Health Sensing System, which delivers the most accurate heart rate sensing in a wearable. 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, so the picture of your health is far more complete. Every morning a Readiness score tells you how much your body has to give, and it keeps adjusting as your day unfolds.

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.

This is the thinnest Apple Watch ever made, with a larger always-on display than before. The wide-angle Retina display reaches 2,000 nits in bright sun and dims to a single nit at night, and Ceramic Shield 2 makes the front tougher than any other smartwatch glass, 60 per cent tougher than Ion-X. 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. GPS models keep you connected through your iPhone for calls, messages and Apple Pay, while GPS + Cellular models stay connected on 5G and LTE on their own.
