For today, we gathered up a bunch of chalkboard clocks, some of them with simple messages  like “see you later”, some of them more fancy. However, they all have something in common: the possibility of bringing your own contribution. Whether it is a note you wish to leave behind for your loved one that day, or a crazy doodle, these interesting wall clocks can get your creativity going. Large or small, round, oval or square, they all feature a writing space and a sponge in order to erase the things you want and renew your “creations”.
