What a clever idea:
The chronotebook was a judges’ prize winner in last year’s Muji Award International Design Competition and is available in Muji stores across the globe. The notebook chucks out the gridularity of the typical day planner and puts an analog clock in the middle of the page.
It’s the simplest manifestation of what a day planner is all about: time on paper. The clocks occupy a small amount of space on the page and rest is completely flexible. You can write in your own dates at the top of each page, and you can treat the rest of the space like a blank page.
