Clock system in my fantasy world

I didn't want the time-measuring system of the fantasy world to be a copy of ours, with 24 hours per day, 60 minutes per hour, and so on. It is very arbitrary and precise. However, I do want towns to have clock towers, and people to have an established way to communicate about time.

Halving, powers of two, and so on have always felt like a very natural way to divide up quantities of things to me. Dividing up the clock face, each half being divided into eighths seemed like a good place to stop. I want it to be something just about anyone (who has been measuring time that way their entire life) could glace upward (or at a shadow) and figure out correctly.

Putting noon at the top and midnight at the bottom means a vertical clock face becomes a representation of the height of the sun, which makes the whole system more intuitive.

I used "Morn" and "Eve" for the morning and afternoon/evening signifiers because they are both one syllable and they aren't the names of noon and midnight. "Half Noon", for example, might be less intuitive about whether that meant half a day past noon, or half a day until noon, or half of some other unit of time past/until noon. "Half morn", however, pretty easily expands to "Half way through the morning."
