One of the key aims of this site is to be a source of information for those who collect vintage Grand Seiko. We don’t just list the watches that we have for sale in the anticipation that customers will add them to their collections – we also list watches that we have never had in stock, along with as much data about those watches as we can glean. The intent is to be a reliable source of information about exactly which references were created by Grand Seiko, and to provide data on those references.
We are confident that currently this site contains the most complete, accurate and detailed information on the historical Grand Seiko references that you will find anywhere.

The Seiko 1967 no. 2 supplement catalogue
We have not been able to track down an original example of this publication. Even the Seiko Museum in Tokyo only have a photocopy, and it is from this photocopy that the scan shown in this article is taken from.
This catalogue marks an important milestone in the history of vintage Grand Seiko, as it introduces the first watch in the 44GS series – the 4420-9000, famous for introducing Taro Tanaka’s legendary “Grammar of Design”.

Grand Seiko 4420-9000
There are actually two dial variants of this reference, with this catalogue featuring the reference with the earlier “Diashock” dial. The later dial design, that makes a single appearance in volume 2 of the 1968 catalogue, removed the line of text “Diashock” and replaced it with the logo for the Daini-Seikosha factory.
Today, given its relatively short lifespan and seemingly low production quantities, this reference from the 44GS series is extremely collectible.
