'Real' moon clock. It's largely based on its predecessor the Panel-meter-moon-phase-clock with the big difference that instead of a panelmeter it has a rotating moon which depicts the phase of the moon.
Installing the back panel a fiddly job because it's a little cramped inside. The top row of buttons are (ltr) set/next, up, down and esc. the bottom row are daylight saving switch, time set potentiometer – because the clock works with UTC time you can adjust the time with the potentiometer to your local time – and the last switch on the row turns the full-moon light on or off.
