For me, day/night indicators make watches feel that they are "Alive" haha.
I like how they slowly change its face throughout the day in sync with the actual sun and moon, different face different feeling.
I have a JLC M8D, however its day/night indicator has a more simpler design: Day with it's brass Sun gives the watch a warm and bright feel. And the Night with its stars on a dark blue background gives it a calming feel, it's like telling me that the day has ended, it's time for me to rest and relax ^^
Once again, that's a nice watch with a great design.
Have a great weekend=)
Best Wishes,
