Apple Watch SE (3rd gen)

The SE 3 closes most of the distance to the Series line without moving off $249. It gains the always-on display the SE has always lacked, the S10 chip, wrist temperature with retrospective ovulation estimates, sleep score, sleep apnea notifications, and charging that reaches 80% in 45 minutes — the SE 2 took two and a half hours to fill. What is still absent is the electrical heart sensor and the pulse oximeter, so no ECG app and no blood oxygen, and hypertension notifications need a newer optical sensor than this one has. Irregular rhythm alerts, fall and crash detection, and Training Load are all here. Battery stays at 18 hours.
