Starting in 1966, Seiko began to publish catalogues detailing their range of watches. Over the course of several years, I have been able to build up a complete collection of catalogues covering the vintage Grand Seiko years (and indeed beyond). On starting this Substack I thought it was a good opportunity to re-publish a series of articles I have written on the catalogues. These articles first appeared on The Grand Seiko Guy website, but here I have the chance to publish them in chronological order.
