State of the collection – the 56GS movements

A write up of the vintage Grand Seiko watches in my collection that utilise the 56GS movements.

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 56 series of vintage Grand Seiko is second only to the 61GS with regards to the diversity of the watches produced. Whilst utilising only three different movements (there are no “special” or “VFA” examples in this series), there are over 40 variations with differing cases or dials.

State of the collection – the 45GS movements

A write up of the vintage Grand Seiko watches in my collection that utilise the 45GS movements.

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.

State of the collection – the 61GS movements (part 2)

Part 2 of a write up of the vintage Grand Seiko watches in my collection that utilise the 61GS movements.

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.

The 61GS series started production in 1967, running all the way through until 1974.

With seven different movements, there are as many calibers being utilised within this single series as in all earlier series combined. Not only that, but numbering over 40, there are more individual 61GS watch designs than existed across those earlier series (the Grand Seiko First, 57GS, 44GS and 62GS).

Given the extent and diversity of the 61GS series, it is not feasible to discuss all the examples from my own collection in a single post, and as such, I have split the write-up of the 61GS over two separate articles.

A link to the first article – covering the watches in my collection that utilize the 6145A and 6146A movements – can be found here.

In this article, I will be covering the watches in my collection that utilize the remaining 5 movements from the 61GS series – the 6155A, 6156A, 6185A, 6185B and 6186B.

State of the collection – the 44GS movement

A write up of the vintage Grand Seiko watches in my collection that utilise the 4420B movement.

Note quite sticking to my original planned schedule, I will continue to be posting articles on my collection of vintage Grand Seikos.

Since there are over 40 pieces in the collection, it makes sense to break this 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!

Developed from the 44 King Seiko Chronometer that used the earlier 4420A movement, the Grand Seiko 44 series were the first Grand Seikos from the Daini Seikosha company, and launched in 1966.

State of the collection – the 62GS movements

A write up of the vintage Grand Seiko watches in my collection that utilise the movements from the 62GS series

Between now and the end of the year I will be posting articles on my collection of vintage Grand Seikos.

Since there are over 40 pieces in the collection, it makes sense to break this 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.

Grand Seiko 6245-9000

Traditionally following the 57GS series would be the 44GS, but since all my 44’s are from 1967, and I have two 62’s from 1966, it’s the 62GS that is up next.

Starting its life as a “regular” Seiko, the 6245 movement was first introduced in the Seikomatic Chronometer. In the second half of 1966, Seiko had to drop the use of the term Chronometer due to objections from the Swiss COSC, and thus the first automatic Grand Seiko was born.
