I came across a Seiko 6139-6007 recently, and it occurred to me that I'd never seen one before. I'd like to poll the members here to try to collect as much knowledge as we can...

Some assumptions I have - please prove me wrong if you can, or back me up if you like

• All 6139-6007s are blue, and all have RESIST dials and WATER RESISTANT case backs
• The earliest observed is November 1970; latest is January 1971
• They all have English/Spanish day wheel
• Some have 6139A (but with 1-piece chrono hand) movement, some have 6139B (not sure about the overlap or proportions of A vs B)
• None have a notched case
• They all have 6009T dials, meaning 17J below the centre, and only SEIKO AUTOMATIC (no CHRONOGRAPH) - ie looks like a North American watch
• They all have DAINI SEIKOSHA on the rotor, also like the US market watches
• They all have either aftermarket bracelets, straps or original non-tapered H-link SEIKO bracelet

There have been a few threads on various forums over the years but nothing I can find conclusive - so let's see if we can crowd-source the answers here, eh?

When my 6007 arrives, I'll put up some pics of it here 🤓

 

[ewand]

I wonder if they were produced for Latin America or Canadian markets? Or maybe an overseas US region like Hawaii or Puerto Rico?
Or maybe they were US market watches which took over from the 6009 (do all blue 6009s have notch case, 6139A, 2-piece chrono?), and were replaced when the 6005 came out?

 

[alexblex]

Some time ago when I got my 6007 I researched a bit. The handfull pieces figured out of a web search are all dated End of 1970, October, November, December.
My 6139 6007 has exact same configuration like the 6005/6009, with a 6139A movement.
It has a Spanisch - English daywheel.
I would assume the 6007 was destined for Central and South America.

 

[ewand]

Yeah, I wondered if they'd all have English/Spanish day wheel too. I have a July 1971 blue RESIST 6005 that has English/Spanish too, so I'd imagine that's a typical arrangement for the Americas market.

@alexblex - what's the year/month of your serial no?

 

[alexblex]

My 6139 6007 is from December 1970.

 

[Grammarofdesign]

I had been led to believe the -6007 was intended for the Latin America market. I've had at least one if not more along the way. Wish I had captured the case back serial numbers.

 

[Thesharkman]

so, this config only came with a blue dial?

<* shark >>><

 

[byscott]

I’ve only seen them with blue dials. I‘ve been looking for one for a couple years to complete the set of each reference with a blue dial. Ewan’s is definitely one of the nicest examples I’ve seen.

 

[ewand]

<* shark >>><

That's my contention. Show me a verified 6007 with a non-blue dial (and I guess at this point, we might need to be talking about the back of the dial verification - whatever, we'd be looking at a 6009T dial) ...

 

[ewand]

Alright-y. A package arrived for me today...

Here she is - looking really good, everything works well (it appears) - movement is fairly clean though no case back gasket so I presume not serviced by anyone competent, any time recently... the bracelet is in very good shape with hardly a mark on the clasp, so I wonder if it's a (correct) replacement. The movement inside is 6139A which contrasts with a blue 6005 that I have from July 1971, which used a 6139B, and Bertnet's 6007 from Nov 1970 which has a 6139B. This watch is January 1971. The day wheel is in Spanish, as is the 6005 - so I presume it's Caribbean or Latin American...?

Interestingly, SEIKO TIME CORP on the 6005 is engraved in a semi-circle at the top of the inner case back, rather than straight across as it is on this 6007.

The bracelet is really short, but that's fine - it fits me perfectly.

But here's a bonus... the auction listing didn't say anything about there being a box, and yet it came in an unmarked blue one.

Opening up the box, there were some papers stuffed into the lid, obscuring the SEIKO logo - removed, and with watch installed, it looks very nice indeed.

Papers? What kind of Papers?, I hear you ask...

Well, for one...

... and it's got the watch number written on the back so I'm of the belief that it's original:

 

[ewand]

Oh, and one more thing:

I wonder what Area Code: 307 means? Presumably not a Wyoming dial code... maybe a regional code for where Seiko shipped the guarantee? Presumably 69-10 is the date of the guarantee booklet? Anyway, what's inside the guarantee... could it contain a dealer stamp showing where the watch was sold from, answering the mystery of which geography the 6007 was from?

D'OH!

I asked the Seiko Museum if they knew where the 6007 came from, and they replied (fairly quickly, to be fair):

Thank you for your inquiry.
We looked up in the international catalogs we have but we could not find any information about
where 6139-6007 was made to be sold unfortunately.
We are sorry that we could not be any help this time.
Thank you for your understanding and thank you for your interest in Seiko!

Best regards,
Seiko Museum Ginza

Nice pick up and a very nice bonus getting the papers.

You bagged a good one there Ewan.

She's a Beauty Ewan!

When I have time I'll locate one of my 6007's and see how it matches up.

WTB 6139-6007

Ewan’s recent post regarding his 6139-6007 reminds me that I had meant to put out a WTB ad. I’ve been looking for one for a while now to complete a set of each reference with a blue dial. Please PM me if you have one for sale or trade. Thanks!
