It's kinda crazy that in following the circular motion around the numbers go upside down from the perspecitve of the reader. I've never owned a watch that does that.
yeah it's weird when you think about it because you're looking at it from a certain view, however, a reasonable explanation is that if you change the way the numbes are, then you would have to do it for all of them or it would create confusion. It's weirder even to see that roman numbers came into clocks long after the romans, or so I've read.
I read a chapter on a book about time and human perception of it, I can't remember the name and it was in Spanish, but it had all kinds of cool little stories and facts about time and when humans started to keep track of it, initially days and nights, season for crops, then developing a calendar, revising it a few times, and nowadays that we track milliseconds. Long story short, the first chaper was about clocks, watches, its evolution, why we have the numbers that we do, when they were implemented, etc.
