Apple Watch SE 3 (44 mm, GPS) / Apple Watch Series 10 (46 mm, GPS, aluminium)

A 40 mm version also exists with different size, display and battery values.

The aluminium version uses Ion-X glass; the titanium versions have sapphire crystal.

Because the LTPO panel can lower its refresh rate, the display keeps showing the time and notifications with the wrist down; this is the first SE with Always-On.

Up to 2000 nits and down to 1 nit. Apple says the wide-angle OLED looks up to 40% brighter when viewed at an angle, making the watch easier to read without raising the wrist.

Apple claims 4x better crack resistance than the SE 2.

The S10 enables the Always-On display, double tap and wrist flick gestures, on-device Siri and fast charging.

There is no ECG or blood oxygen sensor. The temperature sensor is not intended for medical use.

Feature availability varies by country.

Wrist flick dismisses notifications and calls, silences alarms and returns to the watch face with one hand.

This is single-frequency (L1) GPS; position can drift under trees and between tall buildings.

In Apple's test the watch stays connected to an iPhone over Bluetooth throughout; results vary with use and settings.

Times are with the included Apple Watch Magnetic Fast Charger to USB-C Cable; no adapter is included.

An iPhone is required for setup and use; it does not work with Android phones.

The electrical sensor enables ECG recordings and the optical sensor continuous heart rate. Availability of health features varies by country.

Suitable for shallow-water activities such as swimming, not for scuba diving or high-velocity water sports. The depth gauge is for snorkelling down to 6 metres.

This version has no cellular connection, so calls and data away from the phone need Wi-Fi. Location uses only the L1 band; there is no dual-frequency GPS.

Fast charging uses the included magnetic fast charger to USB-C cable; the adapter is sold separately.
