Introduction

The mechanical World Time watches produced by Seiko from 1964 to 1976 have an elaborate and fascinating history of tweaks and changes over the roughly 13 year production run. In all, there were 4 different major releases, each with a different case design. These break out into 6 model numbers, with at least 16 different dials, 13 different reference city bezels, and at least 7 different case backs. Those numbers grow further if we were to break out dials and casebacks by dial codes, case manufacture code and other smaller differences.

There were also at least 4 special editions, including the first model for the Tokyo-hosted Olympics of 1964, a post-olympics dolphin case back version of that first watch produced only in December of 1964, the Asian Games edition in 1966, and a gold/gilt cased later edition in 1972.

That is a lot of watches.

Now add in 50 years of servicing and repairs, cobbling together watches from parts, adding after-market bits, and perhaps even a little Seiko-modding culture, and we are left with a challenge sorting original and authentic watches from the resto-mods and hack-jobs.

Data Context

The data presented here is intended to assist enthusiasts, owners, collectors and sellers in making educated assumptions about original characteristics and production numbers associated with each model. It is organized to allow ongoing adjustment and addition of data, with all data detail available to anyone interested in cross checking the source information.

With 712 watches now cataloged, and assuming a production of 1,000,000 total watches, we have a margin of error of 3.671%. Despite the high level of statistical accuracy, we are still only looking at somewhere between 0.027% and 0.117% of all produced watches being accounting for in this data set.

Research Method

The dataset used here is derived from images found via internet search engines, across various online sales platforms and from various markets, including the North America, Europe, the Philippines, Malaysia and Japan. This image data is then computer analyzed to generate a base line data table of model and production year information.

With the basic image data processed, metadata information is then appended to each cataloged item, including things like dial codes, GMT hand color and shape, etc. This additional metadata was based on a human review of the images, and prone to (some) error and revision.

NOTE: I have run across several watches with either the case and/or caseback from an incorrect model (e.g. 6117-6410, 6119-XXXX, etc). These watches have been omitted from this study, because without an authentic caseback we cannot accurately attribute the rest of the watch's originality.

Tips for Exploring this Data

Here are some quick tips to make sure you get the most out of this article and its associated data.

The data presented here is dynamically generated

Repeat visits to this article may offer different and evolving detail. Keep note of the total watches cataloged. As that number changes, the summaries and detail will also change. In addition to the data presented in tables, you will also see numbers styled like this - indicating an in-line calculated / dynamic value.

The Production Summary by Year serves as a page index of sorts

Clicking on the year will scroll you to the start of the Production Detail for the selected year. Clicking on a Serial Number will open a Details view pop-up screen, with Next/Previous options to navigate through the data.

NOTE: The floating TOP button at the bottom right of the article will return you to the Summary by Year if you are in the detail, otherwise it will bring you back to the top of the article.

Be sure to visit the Model Summaries

And click the to "Expand" to view more detail, such as break-out of dial colors, specific model numbers, etc.

Throughout this article you will see icons

These are drilldown options, that will open a new tab to the Data Explorer, applying the selected filter to show the data detail. The Data Explorer has two options - viewing the data in a grid (with filter and sort options) and a Thumbnail Gallery view. The Thumbnail gallery gives you a quick view of all selected data records from the grid view.

NOTE: You can also access the Data Explorer via the Page navigation at the very top of this article.

Toggle image thumbnails on/off in Production Detail

Finally, there is an option under the main title/image of this article that allows you to toggle the page to display watch image thumbnails throughout the Production Detail by Year and Month. When activated, this can increase the page load times - as there are literally hundreds (or thousands) of images that need to be loaded.

Even if you do not show these thumbnails, you can always click on a Serial Number to view image and metadata detail.

Summary and Detail by Model

Each model listed includes summary break-out detail - displayed when you click the EXPAND/COLLAPSE MODEL BREAK-OUT text. Only attributes which vary within a model are displayed - for instance all GMT hands are the same in 6117 models so there is no data break down by GMT hand for those models.

Alternate Dial Colors - 6117-640X

While many aftermarket dials aim to replicate the look of the OEM dials, there are a couple dial variants found in the 6117-640X models that need a closer look. Namely the black linen with gray 24 hour ring, and the black linen with yellow 24 hour ring.

Dial Color Just the odd-balls here	Earliest in Catalog	Latest in Catalog	Count	Relative Percent using earliest and latest cataloged	Percent of whole model run
Black Linen (gray 24 hour ring)	1969-12	1976-07	40	10.44 %	10.20 %
Black Linen (yellow 24 hour ring)	1969-12	1975-07	16	4.27 %	4.08 %

Regarding the Black Dial w/ Yellow 24-hour ring

It seems plausible that that some of the original black dials with red/orange 24 hour rings suffered significant fading from sun exposure, rendering this yellow color. They are not common, currently accounting for 7.7% of all black dials in this series.

Regarding the Black Dial w/ Gray 24-hour ring and Silver reference cites bezel

Based on the following observations, it is believed that this dial and bezel combination is be original, despite the lack of ad or catalog scans.

Examples run the entire production length - from 1969 through 1976
19.2% of the cataloged examples of black dials are of this variation
All of these are 6117-6400's - no 6117-6409's.
This subset appears with WORLD TIME at both 6-o'clock and 12-o'clock, with the 6-o'clock examples all dating before 1971 - matching the larger data set for this model
The details on the dials seem to be accurate (lume application, SEIKO logo, 24-hour ring font and text, etc)

ALSO NOTE: There are a few other dial setups that are obviously after-market, including white dial with orange 24-hour ring, white dial with black and red 24-hour ring, and white dial with gold indices. You will find these in the "dials flagged as incorrect" link below.

Series 1 and 3 - Black Dials

Red or Yellow 24 Hour Ring?

The 24 hour ring on the series 1 and series 3 black dials seems to appear in 2 variations, one with white and gold or yellow toned 24 hour ring, the other with white and red or reddish brown 24 hour ring. It is speculated that perhaps the yellow tone is a sun-faded version of the red. Hard to say. Here is a list of all of the dials in question.
