Apple Watch SE 3 44mm Midnight

The Apple Watch SE 3 (44mm, Midnight Aluminum) offers a larger viewing area, enhanced text legibility, and all the core Apple Watch health, fitness, and safety capabilities. Encased in 100% recycled midnight aluminum with a nylon composite and sapphire crystal back, this 44mm model is tailored for wrist sizes ranging from 140mm to 245mm.

Powered by the Apple S10 chip, the device integrates a 64-bit dual-core CPU, a 4-core Neural Engine, and 64GB of onboard storage for offline apps, audiobooks, and music. It brings native support for Apple Intelligence and Siri AI, delivering contextual assistance along with touch-free gestures including double tap and wrist flick. Its larger Always-On Retina LTPO OLED display spans 977 sq mm with a crisp 368 by 448 pixel resolution, reaching up to 1000 nits for outdoor clarity while dropping to 2 nits in dim environments, shielded by Ion-X front glass engineered with 4x improved crack resistance over Apple Watch SE 2.

The watch features a second-generation optical heart sensor alongside a wrist temperature sensor, providing vital metrics such as nightly temperature tracking, sleep staging, sleep apnea notifications, irregular heart rhythm alerts, and retrospective ovulation estimates. Safety systems include Crash Detection, Fall Detection, Emergency SOS, and Check In. Delivering up to 18 hours of all-day battery life and up to 32 hours in Low Power Mode, the SE 3 supports fast charging to reach 80% capacity in about 45 minutes.
