Instead of making you select the hour and minute in two separate steps like most appliances do, you do it in just one. Press the up/down buttons once, and the clock will increment/decrement by one minute. Hold the buttons down, and it moves in ten minute steps for as long as it's pressed.
I thought that was kind of clever. It keeps the task of "Setting the Time" consolidated into a single step, as opposed to breaking it up into as many as three (setting the hour, minute, and am/pm).
