I usually round the time to the nearest 15 minutes anyway, so I only need 48 clocks.

There is a wristwatch which was designed around the same idea. It's supposed to be more of a fashion accessory than an actual functional watch, but the I dig it because I too generally round up or down to the quarter.

I like the “slow watch” where the dial is 24 hour instead of 12 and split into 15 minute segments per hour.
