I don’t follow watchOS updates closely so I only just discovered it. I think it’s wonderful. I love the original Solar Graph face but this one is on a whole ‘nother level. During the winter it helps to know how much sunlight there is left in the day (if any) when I finish at work.
I fell in love with my watch all over again just because of it…
It is both useful and pretty but more than that, it makes you really look at the time from another perspective.
I also like how it manages to remain pretty sober while showing 4 complications on top of all the watchface-specific interactions (day length, seconds ticker, daylight scroller).
