I found it - the table clock Roman by Arne Jacobsen.
The clock was created for Aarhus City Hall in 1942, it features snooze, light sensors and an alarm.
It somehow reminds The Ant and Seven chairs.
A fantastic design object!
It was love at first sight when saw it in a German lifestyle magazine Couch.
I was so sure that can't find it in Budapest, but how wrong I was...found it at Aron Design Store in Mammut 1 and they had all the other models as well in black and white.
