The three top sides are touch sensitive, the top one is a Qi compatible wireless charger that will enable compatible devices to be charged just by placing them on the clock. The left one acts as a snooze button and the right one stops the alarm from ringing. There are no markings on the clock that would indicate this, but for me it was a design choice. Less is more. Relation with Nespresso? The bedside clock will wake you up just in time for that cup of coffee that will jump start your day!
