I appreciate the detailed analysis. The base of the letters and where they start, the A, is UTC. A is UTC +/-0. The idea isn’t the letters, which seem to be the main point in the comment, the idea is the rotating UTC (represented by letters to distinguish local from UTC times) instead of having am extra hand moving. An extra Hand moving will make the clock more complex to read. We’d have 4 hands moving. I think a rotating UTC makes it easier to read. As for the letters, it’s easy to change back to numbers which is then simply UTC itself. It’s an experiment with letters, if it doesn’t work, it can be changed.

Would love to hear your thoughts on the rotating UTC layer vs an extra UTC layer + hand.
