Designed by Wonjune Song, from Connect Design – the Watch Diary is a hardback paper notebook with an analog clock sitting in the middle. Like the Hungry Caterpillar book, which has holes punched in its pages, the Watch Diary has a circle punched through from front to back, allowing the clock to peek out. This, combined with a clever page design, makes for a rather intuitive scheduling tool.

If you like it, you can have it! It is available for 17.00USD.

It is really a useful book for those who always have to deal with various tasks.
