I had a notion to make a 24 hour clock with just one hand. There is actually a watch company selling such a device and their tagline is that the watch "will change your conception of time". I'd like to see if that is true.

Making a 24-hour clock looks to be relatively straight forward. Most clocks rely on pulses from a piezo electric crystal. Divide the pulse frequency by two with a D-flip flop and the clock goes half as fast.

I assume you’re talking about Slow Watches? I actually have one and while I love the simplicity of it, it turns out the minute hand is actually the more useful hand. Trying to figure out if you have 10 or 20 minutes until your next appointment on a Slow Watch is extremely painful, so much so that I only wear it if I don’t think I’ll need to know the time behind if it’s “roughly between 1 and 2 pm”.
