Clocks should use 24h format. AM/PM is completely useless.
No it's not, with a 12h format on an analog watch you can use the sun to find true north. It is also easier to read it when the hands have double the amount of degrees to indicate the number.
Edit -- digital watches should use 24h, I fully agree, maybe there was a misunderstanding because it's analog watches we're talking about here and these could stay 12h IMHO
How do you find north on a 12h face that wouldn't work with a 24h face? Because the method I know, requires correcting for the 12h circle.
I have never seem a 24h wrist watch (I know they exist) aside from extremely seldom as wall clocks

How the heck do you find north based on your watch? I’m pretty good at knowing where north in based on where I am.
I live in north Manchester so I know Manchester is south. Or I can look at the sun if not midday and figure it out.
Like this
What if you go on a trip to Thailand and get turned around in the jungle?
That gives you a very approximate direction.
Thanks.
I don’t generally go places like that, but if I needed to be aware of north I would take a compass.
Still good information though.
It's the same method.
The distance between the sun and 12 is divided by two, because the clock face only shows half the day.
If we had a clock with 24 hours in the circle and used the same method, it'd be the same as pointing at the sun and saying: South is where the sun will be at noon.
