Reference photography not yet on file

The 56KS: an automatic King Seiko, and a Suwa product rather than a Daini one — the internal rivalry blurred as the lines consolidated. The 5625 is the date-only sibling of the day-date 5626.

Some specifications for this reference require verification against manufacturer documentation.
