This is basically the same system as the regular 12:00 clock except noon and midnight are 00:00 instead of 12:00.
Seems functionality the same to me.
24 hour is the only way. If only I could convince people to stay saying “15 O’Clock”. That would be neato. People know what it is, just not used to it
I have one, and that they do, except for the people trying to sneak a glance of the time haha. “Huh?”
I rather love mine, to me there’s little reason to prefer a 12 hour clock when you have minute and second hands on the 24 also (my version does, it’s not a “slow watch”)
