The latest Apple Watch features the biggest and most advanced display yet. It’s the thinnest Apple Watch ever—10% thinner than Series 9—and significantly lighter. Phone calls sound better in loud environments, and you can play media through the built-in speaker. A powerful new health feature—Sleep Apnea Notifications—helps you track breathing disturbances while you sleep. And a new depth gauge and a water temperature sensor make it even more capable in water. See Create a custom workout.
