TIL - this is very cool. It looks like somebody actually put together a wari-koma (temporal) watch in 2011 as well.

If you want to look at some old ones the Seiko museum in Tokyo has a few. Entry is free and I can only recommend it.

Thanks for the tip! The wadokei clocks on the museum's site look incredible.
