The model that introduces an always-on display as a new feature is the Apple Watch SE 3. This model is powered by the S10 chip, which enables the Always-On display for the first time in the SE line. It allows users to conveniently view the time and glance at notifications without raising their wrist or tapping the display. This feature is part of the recent update announced by Apple in September 2025, alongside other enhancements like fast charging and advanced health features.
