Since there are over 40 pieces in the collection, it makes sense to break this “state of the collection” write-up over several articles. Each post will cover a specific movement – or set of movements – from the vintage Grand Seiko releases, and include photos of the watches I have that utilise that movement.
Whilst I don’t intend these articles to provide a comprehensive and thoroughly researched scholarly history of vintage Grand Seikos, I will share some knowledge on the pieces that I have picked up over the course of the last year. If I get anything wrong, please don’t hesitate to let me know!
The 45GS series started production in 1968, continuing through until the early 1970’s. Like the earlier and short-lived 44GS series, they were produced by the Daini factory.
Whilst utilising only three different movements – the dateless 4520A; the 4522A with a date complication; and the incredibly rare 4580 Very Fine Adjusted, there were a good variety of case and dial designs created over this period.
