I suggest installing Sun Dial on youres smartwatch. Especially when daytime is 4 hours, it somewhat aleviates the "eternal darkness" brain fuzz. I try to be awake on those few hours, and do not care about those other dials.
There is Sun Dial right there on Zepp Watchmaker on "editable components". From 9 to 15 seems to best amplitude as it reflects the sun's movement on the skies.
