I just have yesterday to report on, but it seems to work as advertised. Best I can tell, it’s only active from sunset to sunrise, at which point it’s dependent on ambient light.
I do wish, though, that it had a bit of “smoothing” built into its algorithm. That is, I don’t want it changing based on the instantaneous ambient light, but based on the average ambient light over the past fifteen minutes or so (but with a bit of flexibility). That is, if it’s been bright but somebody turns out the lights, I don’t want to be squinting to read night mode. But, at the same time, if it’s been dark and somebody turns on the lights, I may well have my eyes screwed shut and don’t want the watch to think that it’s now supposed to add to my retinal burn when the lights go out again a moment later.
And, of course, I wish it applied to the entire UI, not just the Wayfinder face. This is especially since the new smart stack widget thing (with the crown rotation) has me quite surprised to be seriously considering moving away from Wayfinder. It was my unexpected go-to from when I got the watch … I had preferred minimalist faces until then, but I got really hooked on Wayfinder. Now, though … the stack seems to be giving me the best of both worlds: a simple, elegant minimalist face (such as Contour) for most of the time, but far more than I could get from complications with a quick turn of the crown.
