There are watches that have an actual 24hr face as you describe the normal 6 position is 12 and 12 becomes 24. Which I think are fairly uncommon, I don’t recall ever seeing one in person.
More common to just see analog watches with dual time markings say a 24 under the 12.
An image search along the lines of “24hr watch face” will show some examples.
We’ll see son. We’ll see.
