Grand Seiko 6146-8000

Grand Seiko 6146-8000 in cap gold with early Grand Seiko dial.
The earliest 61GS series watches – this one is from December 1967 – had dials that were laid out in the same way as the late 57GS’s, 44GS’s and 62GS’s. That is, with Seiko up top, and the GS logo and Grand Seiko text down bottom.
Then, just a few months later, the dial layout was changed – the Grand Seiko text was removed, and replaced with the movement description (“Hi Beat 36000”), and “Automatic” added under “SEIKO”. Apart from the VFA’s, these early 61GS models were the last vintage Grand Seikos to actually include the full branding anywhere on the dial or case.
For more background to the dial layout changes that happened during the lifespan of the vintage models, check out my website (link in bio) and click on the “General articles” menu option.
It is extremely rare to come across a cap gold 61GS with the Grand Seiko dial. As such, I snapped this one up despite the fact it wasn’t in top condition – although to be fair, it was an absolute bargain because most people were put off by the apparent state of it.
Ideally needs a new crystal, and a bit of TLC to remove the remainder of the tarnishing on the case (I’ve got rid of the worst of the tarnishing – you should have seen the state of it when it first arrived!). Very happy to have been able to secure one of these for the collection.

Grand Seiko 6146-8010

Grand Seiko 6146-8010.
The 6146-8010 doesn’t turn up very often. It can be easily distinguished by the graphic on the dial around and under the GS logo, often referred to as ‘Arabesque’. Though thought to be a precursor to the 615x “Special” watches, whose movements were regulated to +/-3 seconds per day, this particular example is from February 1971 – fully six months after my earliest Special.
Any contemporary documentation on this watch would be most appreciated!

This one is unique amongst all that I have seen in that it has an factory original custom engraved caseback. As per the engraved dedication, the watch was produced for the 60th anniversary of the Idemitsu company. No other engraving appears on the outside caseback around the gold GS medallion. The model number and serial number both appear on the inside of the caseback.

A most intriguing watch!

Grand Seiko 6145/6-8000

On the left, the Grand Seiko 6145-8000, and on the right, the 6146-8000. Both early variants distinguished​ by the “Grand Seiko” text printed on the dials. Except for the VFA’s, these were the last Grand Seikos to actually mention the brand in full on the dial until the quartz models launched in 1988. All subsequent 61GS, 45GS, and 56GS only featured the “GS” logo on the dial.

The 6146 is from the very first month of production, October 1967. The 6145 from January 1968.

On the block – 12

A weekly series of posts highlighting interesting Grand Seiko watches on the market

“On the block” is the section of the website where I share some examples of vintage Grand Seikos currently available on the Japanese market.

This week continues the normal format of highlighting one watch available from each of the three main channels that it is possible to remotely source watches from Japan – Yahoo Japan auctions, Rakuten, and websites of individual dealers. But with a catch…

In a departure from the usual posts, this week the item highlighted from Yahoo Japan Auctions will be one that I recommend you do not buy.

To discover how to remotely acquire watches from these channels, check out my article on Zenmarket on the “Buying from Japan” page of this site.

As usual, I will be using photos of watches from my own collection to illustrate what is available, but do of course click through the links to check the specific details of the watches being sold.

Yahoo Auctions

After a fairly extended lull in interesting pieces coming to Yahoo Auctions so far this year, this week things have really picked up. There are some great watches across much of the vintage Grand Seiko range to be found, but also a small handful that should be avoided. And for a change, I thought it would be interesting to focus on a watch that you shouldn’t be considering.

A weekly series of posts highlighting interesting Grand Seiko watches on the market

The vintage Grand Seiko market

Each week, I am highlighting one Yahoo auction; one Rakuten listing; and one watch at a Japanese dealer, that I would be happy to add to my own collection, were it not for the fact that it would be a duplication, or a near duplication of a piece I already have.

The Yahoo and Rakuten pieces will be linked through Zenmarket – see my post on them here for details as to why I use this service. Watches available with dealers will be linked to directly, and again – refer to my ZenMarket post linked above to see how to purchase those. Images used will be from my own collection to give an indication as to the watches being highlighted, but of course click through the links to see images of the actual watch being offered.

Each week I try to mix things up a little with regards to the watches that I highlight to ensure there is not too much repetition compared to the previous week. Since there are only seven series of vintage Grand Seikos (3180, 57GS, 62GS, 44GS, 61GS, 45GS and 56GS), this does limit somewhat the pieces that I can select from for the post.

Additionally, you will have noticed – or will start to notice – that the same sellers (be it on Yahoo, Rakuten, or their own websites) crop up with some regularity. This is simply down to two reasons – firstly, because I am limiting myself to recommending “decent” pieces, and these dealers specialise in the mid-upper end of the market; and secondly, because these dealers are the ones who turn over the most watches and hence have the most variety available.

Yahoo Japan Auctions

This week’s pick from Yahoo auctions is an absolute beauty.
