You know what my biggest problem with clocks is? That they just don't require enough effort. Not the case with the manual digital clock, which requires you to update the time manually every minute.
Sure, you'll need a second, real clock on hand to know when to update it. But still, won't it feel good to get back in control of time and the scheduling in your life? Just don't blame the clock when you're late all the time. That one will be all on you.
