I see nothing about whether the dial illuminates. Assuming that means it doesn’t?
Does the activity meter do anything if you don’t install the app on a smartphone? Does the watch function independently at all? I’ve found virtually all activity trackers want you to install their info-stealing insecure app that leaks your data even if they hold to their privacy promises (which many don’t). If this ran on its own, and defaulted to some rough metric (20 steps = 1% kind of thing) when not paired, I’d be in for one. Or two, you don’t know.
