Months w/ zero Production Examples Found, but Production Examples Expected It is expected that no watches were produced in January or February of 1964 and all of 19, except August 1966 with the Asian Games special edition. Total Months w/ zero Production Examples Expected Total Months w/ zero Production Examples Found Here are some quick tips to make sure you get the most out of this article and its associated data. These watches have been omitted from this study, because without an authentic caseback we cannot accurately attribute the rest of the watch's originality. NOTE: I have run across several watches with either the case and/or caseback from an incorrect model (e.g. This additional metadata was based on a human review of the images, and prone to (some) error and revision. 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 image data is then computer analyzed to generate a base line data table of model and production year information. 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. With 624 watches now cataloged, and assuming a production of 1,000,000 total watches, we have a margin of error of 3.922%.ĭespite the high level of statistical accuracy, we are still only looking at somewhere between 0.023% and 0.105% of all produced watches being accounting for in this data set. 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. 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.

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.

Those numbers grow further if we were to break out dials and casebacks by dial codes, case manufacture code and other smaller differences. 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. In all, there were 4 different major releases, each with a different case design. 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.
