The Apple Watch SE 3 redefines value in Apple’s smartwatch line by bringing several premium features into the entry-level tier. Released September 2025, it includes an always-on Retina LTPO OLED display for quick glanceability without raising your wrist. Powered by the new S10 chip, the SE 3 delivers smoother performance and faster app launch times.

You’ll enjoy fitness and health features including heart rate monitoring, sleep tracking, fall detection, crash detection, and water resistance up to 50 meters—so whether you’re swimming, running, or going about your daily routine, it’s built for it. The SE 3 also supports eSIM/5G in select models, bringing more independence from your phone. Battery life is still “all-day” (~18-24 hours depending on usage) with faster charging improvements over previous SE models.
