Calling all owners, collectors and/or aficionados of the Seiko World Time watches from the 1960's and 1970's...

I recently started collecting various watches in this series and have spent a lot of time researching the various models and details. In my brief time with these watches, I have found a lot of "for sale" listings (most in fact) that include aftermarket dials, are parts-bin specials mixing model and generation parts, or in some way or another are not entirely original / accurate. For a 50-ish year old watch, that is to be expected and often times refurbishing one involves some aftermarket or replacement requirements.

In an attempt to organize my research on this series, I am working on a Google Doc, broken into section by model / generation. I am hoping this will be a gathering point for as much accurate information as possible about these watches, particularly their original details - and help out other current and future collectors / owners. I am gathering images from wherever I can find them (google, ebay, etc), and this is all purely for educational purposes.

I am hoping there are at least a few people out there that share my interest in these watches and may be able to contribute to the accuracy and completeness of this document.

Here's the document link - I have enabled comments - please feel free to comment here or PM me.


UPDATE: this document has started to transform into a website, here:

Awesome work. Thank you. I've downloaded already and will check for updates. Just a great reference. Cheers.

Thank you - currently I seem to be making updates every few hours - so keep an eye on it. If anyone has feedback to offer, especially to anything that I have wrong, or to the unresolved items that I have documented - please do!

All great info and appreciate all the work you put into it. Of interest, the lug adaptors for the World Timers were different from the One-Button Chronographs...a detail I didn't notice till I saw all your pics.

If there's any suggestion for a new section it might be one for modern re-issues. As far as I know, the 5M85-0AF0 SUN067P1 Kinetic (I've since sold mine) was the closest non-official reissue of these watches by Seiko:

Are there any 6117-6010/9 and/or a 6217-7010 owners out there?

I would like to confirm that these two watches share the same case - and hopefully confirm measurements (case size, lug to lug, and lug/bracelet size). Fingers crossed🤞

Also, there is at least one other modern World Time from SEIKO that I have seen:



Both black and white dial variants.

IMO they are missing an opportunity to make a proper automatic (not quartz) version.

I've got a 6217-7010. Can't speak to the comparison with a 6117-60xx, however I can report my calipers read:

Diameter: 38.5mm
Lug-to-lug: 44.5mm measured at the tips of the lugs.
Lug width: 19mm

Caseback date on mine is November 1967.

From pictures I've seen, I'd venture to guess that the black sunburst dials all had the same color yellowish/brownish/reddish chapter rings that have faded to different shades. I doubt Seiko made different dials for this model, at least not intentionally.

Thank you! I've updated my info on that model. Really appreciate - this is a very hard model to track down! I have a Dec 1967 case back documented - so no proof it ever was produced in 1968.

On the black/gray sunburst dial, I am intrigued. I have a 6217-7000 black dial with the white and yellow 24 hour ring. I didn't know what to call that color - but one of the scans calls it "Yellow". I also have clear pictures of the white and burnt red/orange 24 hour ring on the black dial - initially I thought this was introduced in the 6117-601X, when the GMT hand went red - but I have found this dial on the 6217-7010 and the 6117-601X - and those dials are otherwise very different. Also, this one is listed in their catalog scan.

Hold on, actually you can see them both here in the same photo:



Per Microsoft Translate: 5) SEIKO World Time / 17 jewel dial shot colored yellow and white to make the 24-hour display easier to understand.

For some reason the translator is not giving me the wording for #7.

Here's the reddish one in the a catalog shot from the 6117-601X models:



And these seem legit on the 6217-7010:





Its possible the yellow color is a faded red color - but I currently believe they are actually two separate dials. TBD

Also note, on my black dial w/ white/yellow 24 hour ring, the bronze GMT hand seems to match - like that was intentional. The later version's short red GMT would also match the white/red 24 hour ring - and make sense. The one that makes less sense is my last photo above, where you have the bronze GMT hand with the white/red 24 hour ring... that is odd.

Does anyone have a catalog scan or ANY ad scans of the 6217-7010? I can't seem to track one down.

From my '69 casing parts catalogue it would appear the cases are different

6217-7010
Material: SSWP Screw In
Glass: 350W02AN
Case Back: 003280B
Crown: 60W02N
Winding Stem: 357500

6117-6010/19
Material: SSWP Screw In
Glass: 340W06AN
Case Back: FH2920B
Crown: 60W06N
Winding Stem: 357611

That is interesting. I hope to find someone who owns both of these to confirm - could it just be to get the different model number on the case back, you would need a different P/N?

I am also discovering that the 6217-7010 may have several versions - the Asian Games case seems to retain the 6217-7000 dial (no lume), but take the new case and bezel from the 7010 (the inner cities are in blue text on the white bezel for the 7010 vs the outgoing 7000 where all cities were black text). Then the standard 7010 watches appear to have the new lumed dial - but then some owners report having 7010's with standard cases and still no lume on dial.

Curious if the parts catalog you have has any clues on that? It would be 1966 and 1967

Ok - I've made some major updates the 2nd generation watches in the Google Doc. It seems that the Asian Games version was likely only manufactured in 1966, and retained the dial (no lume) from the previous generation watch. Then it appears in 1967 we see the first lumed dial, but in the same model no and case. Any 6217-7010 owners - can you confirm your year of production, dial and Asian Games vs Standard case back?

So far, I have documented 3 different case designs across 4 major releases (5 if you count the Asian Games as a separate watch). These break out into 6 model numbers and give us at least 14 different dials, 10 different bezels, and 7 different case backs - whew ...

I've also added a concise list of the outstanding questions / unresolved items I have from the Google doc into the first post in this thread - will try to get it up to date as my information finds itself to me

That photo is very interesting! Showing the 1st, 3rd, and 4th generation World Times all together. That definitely shows there are separate yellow and more reddish versions, but whether both were used on 6217-7010s is another question.

Here's a couple pics of mine. It's got a standard "horseshoe" caseback. I'd describe the color of the nighttime portion of the ring as bronze.

Thanks - is it a 1967? So far all of that dial style I have found are 1967 only. I have that same 24-hour ring style on a 6217-7000 and also think of it more as bronze. I think it was meant to match the GMT hand.

I should have said - excellent example - I love that watch, and am currently on the hunt for a good example to add to my collection as well.

Along with confirming the manufacture year - do you have calipers to confirm the case size and lug to lug? [edit] sorry Jamaha - I see you already shared that info a while ago - my mind as turned to mush working through all the variations of this watch.

If you have a 6117-640X - or have time to google around and check any images or listings - please note the month/year of production.

I am trying to determine the earliest and latest dates for this model. So far the earliest I have seen is Dec 1969 and the latest is August 1976. Any earlier or later than that?
