I love the originality of this, so 5*! It looks like a chaotic intersection…

A leather strap might work well, good idea. I tried at first to continue the design on the metal strap, but it looked too “busy.” Maybe it can be done, but I didn’t find a solution I liked myself.

And I also tried using four long thin lines for the extra minutes, as you said, but it became too crowded. One of the challenges of this idea was finding a permutation where there is a pleasing distribution of negative space. Many permutations result in one large region of negative space and many tiny regions, so, although I said in the description that the clock positions were paired randomly, what I really did was to select the best permutation from among several random ones.

Other visual considerations for selecting the permutation were to avoid parallel lines, avoid pairings going straight across the watch, and avoid obvious symmetries. There are still symmetries in this permutation, and it’s an interesting mathematical problem to characterize the types of symmetries that arise from all designs like this.

Anyway, thanks very much for your support!

Thanks, Lloyd!
