years ago in Japan daylight and nighttime were each given 12 hours and clocks were made to adhere to this ... throughout the year as summer days grew longer and nighttime shorter their clocks adjusted to make an hour longer or shorter self adjusting

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.
