Hours and minutes- you’d only need two. Make the gears coaxial, hours on outer gear and minutes in five minute intervals on inner gear.

It’s Catena, and I made a typo when I wrote this post halfway in my sleep. I’ll correct this now

Is it Cantena or Catena? You’re using both spellings.

“The only numbers on the chain are the hours, so any attempt to figure out minutes is a crap-shoot.”
That depends, how many chain links are between each of the hour numerals, you could probably suss it out that way.

Someone needs to put 4 of these together and make them tell the whole time
or even five 4 digits one am and pm one. but of course they need to make them extremely cheap first.
