Apple Watch SE 3 (GPS + Cellular) 44mm Starlight Aluminium Case with Sand Sport Band, M/L

The new Apple Watch SE 3 (Aluminium case, 44 mm) brings the essentials of Apple Watch to the most accessible price in the range, on the larger of the two case sizes. An always-on Retina display with 977 mm² of screen means a glance is all it takes to see the time, your rings or your next notification, and the second-generation optical heart sensor keeps an eye on your heart rate through the day, with alerts if it goes unusually high or low and notifications for irregular rhythms.

SE 3 is a capable training partner across running, cycling, swimming, yoga and HIIT. Workout Buddy, powered by Apple Intelligence, gives you spoken, personalised encouragement based on your heart rate, pace and progress, and the Workout app makes it easy to build custom sessions, follow your goals and stay motivated with Activity rings, trends and awards. Up to 7 hours of outdoor workout tracking covers the long ones.

The 44 mm aluminium case weighs 32.9 grams, fits wrists from 140 to 245 mm and stays comfortable enough to wear overnight for sleep tracking. Tough Ion-X front glass stands up to knocks four times better than before, water resistance to 50 metres covers pool lengths and open water, and the wrist temperature sensor adds overnight insights and retrospective ovulation estimates. Battery life runs to 18 hours of normal use, or 32 hours in Low Power Mode.

The S10 chip with its 4-core Neural Engine keeps everything quick, and watchOS 27 adds Siri AI, Audio Intelligence features and the dynamic app grid. GPS models keep you connected through your iPhone for calls, messages and Apple Pay, while GPS + Cellular models stay connected on 5G and LTE without your phone. Emergency SOS, Fall Detection and Crash Detection are there when they matter.
