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 November 1967 issue of Seiko Sales features the 5722-9991 on page 10. From the image, one can clearly see that the watch has the fine knurled crown.
Both stainless steel and gold cap cased versions of the reference are detailed.
