About the Apple Watch SE 3 40mm
Apple Watch SE 3 is Apple's most affordable current watch, and this generation adds features previously reserved for higher models. It runs on the same S10 SiP as Series 11, now has an Always-On Retina display, and supports fast charging. Apple rates battery life at up to 18 hours, or up to 32 hours in Low Power Mode.
SE 3 tracks heart rate, sleep with Sleep Score, wrist temperature for cycle tracking, and offers sleep apnea notifications, fall detection and crash detection. It does not include ECG or blood oxygen measurement. The 40 mm case suits smaller wrists, and storage is 32GB. SE 3 is offered in GPS and GPS + Cellular models; check the box for the model in stock.
