The display reaches up to 1,000 nits peak brightness and can dim to 2 nits. Apple also uses tough Ion-X front glass with 4x improved crack resistance compared with the previous generation.
Series SE 3 remains available in familiar 40mm and 44mm sizes.
Apple S10 Chip
Apple Watch SE (3rd Generation) is powered by the S10 chip with a 64-bit dual-core processor and 4-core Neural Engine.
It also includes 64GB of storage, providing plenty of capacity for watchOS, apps, music, and other supported content.
The S10 enables features including the Always-On display, faster on-device Siri processing, gesture controls, and improved everyday performance.
Double Tap & Wrist Flick
Apple Watch SE 3 supports both Double Tap and Wrist Flick gestures.
Double Tap allows users to tap their thumb and index finger together twice to perform the primary action in supported apps and notifications.
Wrist Flick provides another one-handed control method, allowing users to dismiss certain notifications and calls or interact with supported watchOS features without touching the display.
Temperature Sensing
Apple Watch SE 3 introduces wrist temperature sensing to the SE family.
Apple uses two temperature sensors and algorithms designed to compensate for environmental temperature. Wrist temperature information can contribute to supported wellness insights and advanced cycle-tracking functionality, including retrospective ovulation estimates for eligible users.
Heart Rate Monitoring
The watch features a second-generation optical heart sensor and supports the Heart Rate app, high and low heart-rate notifications, and irregular rhythm notifications.
Unlike higher-end Apple Watch Series models, SE 3 does not have an electrical heart sensor for the ECG app.
Sleep Score & Sleep Tracking
Apple Watch SE (3rd Generation) introduces Sleep Score, providing users with an easier way to understand their overall sleep quality.
It works alongside existing sleep features such as sleep duration and sleep stages. The watch also supports sleep apnoea notifications for eligible users in supported regions.
Fitness & Activity Tracking
Apple Watch SE 3 supports a broad selection of workouts and everyday activity tracking.
Depending on the activity, it can track metrics including heart rate, calories burned, pace, distance, workout duration, elevation, and GPS route information.
Apple’s Activity system also tracks daily Move, Exercise, and Stand goals.
Safety Features
Apple Watch SE (3rd Generation) includes important safety capabilities such as Fall Detection, Crash Detection, Emergency SOS, and Check In.
These features can help users contact emergency services or keep selected contacts informed in supported situations.
GPS & 5G Cellular Connectivity
Apple Watch SE 3 is offered in GPS and GPS + Cellular versions.
Cellular models introduce 5G cellular capability, providing improved cellular performance and faster downloads when used with a compatible carrier and active plan.
GPS + Cellular models can support calls, messages, streaming, and other connected functions when the paired iPhone isn’t nearby, subject to carrier support.
Compass & Always-On Altimeter
Apple Watch SE 3 includes a built-in compass and always-on altimeter, providing direction and elevation information for compatible workouts and applications.
These features are particularly useful for outdoor activities such as walking, running, cycling, and hiking.
Water Resistance
Apple Watch SE (3rd Generation) has 50-metre water resistance, making it suitable for supported shallow-water activities such as swimming.
It is not intended for scuba diving or high-velocity water activities. Water resistance is also not permanent and can decrease over time.
Battery Life & Battery Health
Despite adding an Always-On display, Apple rates Apple Watch SE 3 for up to 18 hours of normal use.
Our Open Box Apple Watch SE (3rd Generation) units come with 85%–88% Battery Health.
Actual battery runtime varies depending on battery condition, display usage, cellular connectivity, workouts, notifications, applications, settings, and network conditions.
Fast Charging
Apple Watch SE 3 is the first Apple Watch SE generation to support fast charging.
Apple states that it charges up to 2x faster than the previous generation. Around 15 minutes of charging can provide up to 8 hours of normal use, while approximately 45 minutes can charge the battery to around 80% under Apple’s testing conditions.
Open Box Condition
The Apple Watch SE (3rd Generation) is available in Open Box condition with 85%–88% Battery Health.
