Garmin CIRQA Smart Band
It lasts up to 10 days, and the module weighs 14.8 g. It has no GPS of its own, and Garmin Coach and guided workouts need a Connect+ plan.
6.9/10
This score is my reading of published evidence, since I haven't worn the band. I scored it conservatively: no 30-day test or sleep-lab study turned up, and testers hit real gaps in wrist intervals and workout detection.
