There are several presets and controls to create other layouts. You can set 11 or 13 hour markers yourself and see how it looks. The controls on the page are simple, with only one number and a few toggles. But those are enough to create all valid layouts. When first exploring the idea, I had low-level controls to set angular size for each set of marks. All layouts other than what the current controls allow would have issues - several alignments that make time ambiguous or minute marker not aligning at 12 after an hour passes. The preset where the ring rotates once in a week has both hours and minutes in order. But because of the extremely slow rotation, the minute indicators take less than a half of the circumference.
