Apple Watch SE 3

Xiaomi Smart Band 9
At just $49, the Xiaomi Smart Band 9 is the pound-for-pound champion of ultra-budget fitness trackers, upgrading to a sandblasted aluminum alloy frame, a 1,200-nit 60Hz AMOLED pill screen, a linear vibration motor, and a 21-day battery life. An upgraded dual-LED PPG module improves heart-rate accuracy by 16% over the Band 8, making it an unbeatable impulse buy for sleep and step tracking.
