Designed by Marti Guixe for Alessi blank wall clock has no markings at all. It has a write-able surface that can be wiped clear. You can write on the face of the clock with a wipe clean pen. Different hours are represented with the help of words and IS is written in the middle of the clock. The IS helps you connect two words, making a sentence, so that you have a new sentence every time you see the clock. It is a perfect design to have fun with time.
