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.

Yeah, that's the method I know.
And that's how you correct for the 12h face.
Thought as much but never had any experience with 24h watches, so no comment on this from my side :)
With a 24h watch, you line up the hour hand with the sun. Because the sun does a full circle in 24h and the hour hand does the same, lining them up will always make 24 point north (on the northern hemisphere).
A compass is still the better option, because the magnetic field also points north in the southern hemisphere and doesn't have to be recalibrated when you move too far east or west.
I have never seem a 24h wrist watch (I know they exist) aside from extremely seldom as wall clocks
I've looked for them, but they're very hard to find and expensive too. You can't just slap a 24h face on a 12h mechanism, so it's all custom and produced in low volumes. (I think it's technically possible to convert a 12h period into 24h by switching out a single gear, but that might ruin your minute hand too? I'm no clock maker.)
They don't have to be expensive, though such watches are less popular for everyday use. In fact I'm wearing a Vostok Kommendurski with a 12/24 hour dial. When I was a medic, I needed to record all my times in 24hr format on my run reports. I think I paid $35US delivered from Russia 15 or so years ago.
And no extra gear is needed to make an analog watch/clock indicate 24 hour time. Time doesn't change. You simple have one scale that reads from 12AM through 12PM and then at the next hour, (1PM) it simply gets renumbered to 13, 14, 15, 16 and so on until you reach 24 on the inside scale. Easy peasey.
But it is possible to build a watch/clock that the movement does move in 24 hour time and you would be correct it would a couple of extra gears to accomplish. But, it would also be a real pain to create a legible watch face with all those numbers on a reasonable sized watch. Far simpler and easier to print the two scales on the face and call it good.
You paid $35 for the watch, the delivery or both? Because I saw those Vostok watches with proper 24h faces, which is exactly what I'm looking for, but they're $140. I guess that's not super expensive for a watch, but I can get a much nicer 12h watch for that money.
And a double numbered clock face is the simple solution, probably more convenient to read, but also not really a conversation starter :)

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.
It's useless in the jungle, as you can't see the sun.
You don't need to stare directly into the ball of fire to determine where the Sun is. All you need is the flashes of light through the leaves - and you CAN see that in the jungle.
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.
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.
