The Seiko 6139 – 600X Collectors Guide
The Seiko serial number decoder Find the manufacture date of any Seiko watch Seiko watches have a 6 or 7 character serial number on their casebacks. The second character can be a letter but the rest are all numbers. You can use the Seiko serial number in conjunction with the movement number to calculate the year of manufacture. The month and last digit of the Seiko’a date of manufacture is calculated using the serial number and then narrowed down to a decade using my database of Seiko movement manufacture dates.
You will be given an eBay link to check the value, useful links such as manuals, etc and for quartz models the battery information. If more than one date is returned then either I lack data for that Seiko movement or it was made for over a decade.
It may not be the most glamorous or original in terms of design, but the Seiko Some will take issue with the black-on-white day/date indication (pedants like.
In a previous article that detailed the different variants of the reference that were produced over its production lifespan, we mentioned that it is generally believed no more than 36, units were produced of the model. Since the publication of that article, we have continued to undertake research to try to establish a better estimate of production numbers, and also try to get a more accurate handle on the relative numbers produced across the three major dial configurations of Printed, Carved, and Raised logo dials.
One result of this research is that we are extremely confident that we have now also successfully decoded the logic behind the movement serial numbering, something that has — to the best of our knowledge — never been documented before. Stamped on the inside of the case back of the watches can be found the case serial number. Comprised of seven characters, we explained in the previous article how the first two characters of the serial number can be used to determine the month and year of production.
Excepting production in the months of November and December where the year and month codes are reversed , the first character of the case serial number indicates the year of production, and the second the month January through to October are identified by the numerals 1 through 0, November and December are identified by the letters N and D. We discussed in the previous article how, from an examination of many examples of the reference, we had for the first time been able to establish some logic behind the counter part of the case serial number.
We also explained that it appeared that the case number counter was increasing at a faster rate than the movement counter number, thus questioning whether or not it could be used to provide a reliable estimate of production numbers. The movement serial number can be found engraved on one of the bridges of the movement.
Previously it has been suggested elsewhere that the first two digits of the movement serial number can be used to provide an indication of the year the movement was manufactured. However, as we will prove for the very first time in this article, this is not the case. It is clear that at least some of the digits of the movement serial number are a counter, but to-date we believe that no-one has ever managed to crack exactly how that counter functions over the production life-span of the reference.
Without a clear and logical explanation behind the movement serial number counter, we are reliant on the case serial number counter to estimate production numbers. The initial production of the reference — stock manufactured for the launch of the watch — took place between April and June of

Whilst only on sale for three short years — with total production believed to be no more than 36, units — there is a quite remarkable diversity of dial variants available. The purpose of this article is to provide some insight into the dial variations that exist — or at least, the ones that we are aware of at this present time that exist — as well as touch on some other notable differences in features of the watch.
Where stock is available, we will provide links to watches that are for sale. Firstly, the case serial number on the inside of the case back tells us the year and month from the first two digits of the serial number of completion of the watch. In addition, the movement also has its own serial number, and from that number we can get a rough idea as to when the movement was created.
There are three main variants here — printed, carved, and raised. But even within those three core categories, there are sub-variants, some of which have only come to light relatively recently, as interest in collecting vintage Grand Seiko grows substantially with the marketing of the modern brand gaining significant traction globally. Whilst it was originally believed that the printed logo dials were the first to be produced, then followed by the carved dials, and finally the raised dials, it is now clear from having examined multiple examples of the printed and carved logo dialed watches, that these first two methods for creating the Grand Seiko logo on the dial actually have overlapping production, as evidenced by the serial numbers of those that we currently have in stock.
Having said that, it would appear that the printed logo dials were only manufactured in the very early months of production. Whilst very few examples of the printed logo dialed watch have ever come to market, the three that we currently have in stock all have case serial numbers indicating production in the second quarter of Case serial numbers of carved logo dialed watches also would appear to indicated production starting in the second quarter of , but then run all the way through until mid As we will document later on, there are no fewer than four different versions of the carved logo dial watch in existence.
These are of particular interest because they share the same dial code, but are fundamentally different from one another. All together, we believe that there are no fewer than eight different dial variants, and we will discuss each of them in turn, highlighting what to look out for in each reference.

Seiko case-back markings and serial numbers
Over the years Citizen have changed their watch case back markings, whilst they have also used special backs on their high grade watches and certain specific models.

Seiko founder Kintaro Hattori was only 21 years old when he opened the K. After several years of producing high-quality wall clocks, Seikosha released its first pocketwatch, called simply the Timekeeper, in The Hattori quickly recognized the growing worldwide popularity of the wristwatch and predicted that the demand for wristwatches would shortly outpace that for pocketwatches.
The Laurel had a silver case, At first, the need to import components meant that production was slow — just 30 to 50 pieces per day — but by , Seikosha had managed to produce its own balance springs and by , its own enamel dials. The Great Kanto Earthquake struck Japan in , destroying the Seikosha factory and stocks and halting production of timepieces. The use of a non-English name indicated that Hattori had become confident enough in the quality of his products that they would sell despite the widely held belief at the time that products made in the West were of superior quality.
