The Calendar Watch is a simple smartwatch that uses an E Ink display below analog clock hands to show what parts of the day are busy. The watch is controlled by your smartphone - both the calendar display and the clock itself.
The Calendar Watch was originally crowdfunded in 2016, but is now available at retailers such as Amazon starting at $230.
