Reference photography not yet on file

Released on 25 December 1969 as the world's first production quartz wristwatch, in a limited run in 18k gold. Because of its significance, provenance documentation carries unusual weight on this reference and any example should be assessed with reference to Seiko's own archive rather than to market comparables.

Some specifications for this reference require verification against manufacturer documentation.
