Apple Watch SE 3 - 40mm - GPS

A powerful and affordable smartwatch experience is offered by the Apple Watch SE (3rd generation). Equipped with the latest S10 chip, it delivers smooth performance for day-to-day tasks, fitness tracking, and notifications. With both GPS and Cellular options, users may stay connected even when the iPhone is left behind. Fitness and health tracking including heart rate, sleep stages, and noise monitoring are enabled, and safety-focused features like fall detection, crash detection, and Emergency SOS are included for peace of mind.

The display is always on, using an OLED LTPO Retina screen that adjusts brightness up to 1000 nits in bright conditions and lowers to just 2 nits in dim light. Case sizes are available in 44 mm and 40 mm, each with lightweight aluminum finish in colors including Starlight and Midnight. Durability is built in: the device is water resistant to 50 meters for swim use, supports a suite of sensors (compass, altimeter, ambient light, accelerometer, gyroscope) and is designed with crack-resistant front glass. Battery life is optimized for all-day use and extends further when Low Power Mode is used.
