Retina LTPO OLED Display

Apple Watch SE (1st Generation) features a bright Retina LTPO OLED display that provides clear visibility for notifications, workouts, messages, apps, watch faces, and activity information.

It comes in 40mm and 44mm case sizes, allowing users to choose a size according to their wrist and display preference.

Unlike Apple Watch Series 5 and Series 6, the first-generation Apple Watch SE does not feature an Always-On display. The screen activates when you raise your wrist, tap the display, or interact with the watch.

Apple S5 SiP Performance

Apple Watch SE (1st Generation) is powered by the Apple S5 SiP with a 64-bit dual-core processor.

The S5 provides responsive everyday performance for opening apps, tracking workouts, receiving notifications, controlling music, using Siri, checking activity information, and accessing supported watchOS features.

Heart Rate Monitoring

The watch features a second-generation optical heart sensor for heart-rate tracking.

It supports high and low heart rate notifications and can provide irregular rhythm notifications where the feature is supported.

Apple Watch SE (1st Generation) does not include the electrical heart sensor required for Apple’s ECG app and does not include the Blood Oxygen sensor found on certain higher-end Apple Watch models.

Fitness & Activity Tracking

Apple Watch SE can track everyday movement and a variety of workouts. Apple’s Activity system tracks movement, exercise, and standing throughout the day.

During compatible workouts, the watch can record information such as heart rate, calories burned, workout duration, pace, distance, and GPS route information.

This makes it suitable for activities such as walking, running, cycling, swimming, and many other supported workouts.

Built-In GPS, Compass & Altimeter

Built-in GPS/GNSS allows Apple Watch SE to record location and route information during outdoor activities.

It also includes a built-in compass for direction information and an always-on altimeter for tracking elevation changes.

These features are particularly useful for outdoor workouts, walking, running, hiking, and compatible navigation applications.

Fall Detection & Emergency SOS

Apple Watch SE includes important safety features such as Fall Detection and Emergency SOS.

Fall Detection can detect certain hard falls and provide options to contact emergency services. Emergency SOS provides a quick way to request assistance when required.

Availability and functionality of emergency features can vary depending on location, connectivity, carrier support, and other conditions.

GPS & GPS + Cellular Models

Apple Watch SE (1st Generation) was offered in both GPS and GPS + Cellular configurations.

The GPS model can use a paired iPhone and Wi-Fi for supported connected functions.

With a compatible carrier plan, the GPS + Cellular version can provide additional connectivity when the paired iPhone isn’t nearby, including supported calling, messaging, and other online functions.

Water Resistance

Apple Watch SE is water resistant to 50 metres under ISO standard 22810:2010.

It can be used for shallow-water activities such as swimming in a pool or ocean. However, Apple does not recommend it for scuba diving, waterskiing, or activities involving high-velocity water or submersion below shallow depth.

Water resistance is not permanent and can decrease over time.

Battery Life & Battery Health

Apple rated the Apple Watch SE (1st Generation) for up to 18 hours of battery life under its standard usage testing.

Our Open Box Apple Watch SE (1st Generation) units come with 85%–88% Battery Health.

Actual battery performance can vary depending on battery condition, cellular usage, workouts, notifications, applications, display usage, settings, network conditions, and other factors.

Charging

Apple Watch SE (1st Generation) uses Apple Watch magnetic charging.

Unlike newer Apple Watch models such as Series 7, the first-generation SE does not support Apple’s newer USB-C magnetic fast-charging system at Series 7 charging speeds.

Connectivity & Storage

Apple Watch SE supports Wi-Fi and Bluetooth 5.0, along with built-in GPS/GNSS. Cellular models additionally support compatible mobile network connectivity.

The watch includes 32GB of storage, providing space for watchOS, apps, and supported media and content.

When paired with a compatible iPhone, it integrates with Apple’s ecosystem for calls, messages, notifications, Siri, Apple Pay, music controls, activity information, and supported applications.

Open Box Condition

The Apple Watch SE (1st Generation) is available in Open Box condition with 85%–88% Battery Health.

This provides an option for customers who want the core Apple Watch experience without purchasing a new sealed device. Cosmetic condition and included accessories can vary between individual Open Box units.
