More Ceverts to the grid

Someone pointed out that if you Google “International Pogue Day” then the top hit is on this site – in one of the many posts about Seiko’s “Pogue” family and in particular the one from 2019 which talked about International Pogue Day. This is a community-led attempt to get Pogue fans the world over wearing their watches on 16th November and celebrating the anniversary of the blast-off mission to Skylab, on which a certain Col. William Pogue was aboard.


Since last writing about Pogues, I’ve acquired a few more, this time adding a couple of Americans to the mix. The first was a 6139-6005 from July 1971.

The –6005 variants sold in the Americas have a slightly different dial layout than those that went everywhere else – the text below SEIKO says simply “AUTOMATIC” rather than “CHRONOGRAPH | AUTOMATIC” as –6000 and –6002 versions do; it also has the mark of “17J” below the centre, and the dial code on the lower right is 6009T, unlike the –6000 which would be 6030T.

Nobody seems to know why SEIKO felt it necessary to leave out the word CHRONOGRAPH from American watches. Also, even in earliest form, no American watch was marked WATER 70M PROOF – they’re all “RESIST”.


The –6005 was thought to have been produced from 1971-73, and is in fact the version that Pogue himself wore (though it was a yellow dial one). Some collectors happily refer to any Seiko 6139-600x as a “Pogue” while others insist that only a yellow –6005 can be called that, or at least refer to them as “True Pogues”. Oh and the nearer the serial number is to 190945 (indicating Sept 1971 manufacture) then the closer your watch is to the “Pogue” Pogue (this is getting silly – like Paul Newman’s “Paul Newman” Daytona).

When Seiko started advertising the 6139 in the late 1960s, it’s quite possible they expected the blue-dial watch to be more popular and the very first ads featured the blue watches. Only blue and yellow variants were officially available; the silver version has never appeared in a Seiko catalogue so was thought to have been a special order. They were aimed at action men…

This –6005 came to me in pretty good shape on its original bracelet, though it’s not running too well, so is currently in the queue for sending to my favoured watchmaker. He only wants 2 watches at a time from me, so I need to batch them up…


Long-term readers may recall the association with the blue-dial 6139-600x and another famous and sadly deceased racing driver – Francois Cevert – so rather than saying this is a “Blue Pogue”, let’s call it a Cevert. That’ll keep the pedants at bay.

The blue watch in the advert above, and the 1970 “PROOF” –6000 that I had already, both have a distinctive notch above the crown and a 2-piece chronograph hand denoted by the steel centre; both are indicators of the watch having a 6139A movement, which is marginally thinner than the 6139B that replaced it.

You’ll never see a 6139B watch in a notched case (unless the notch was made by some unscrupulous sort, with a Dremel, as the genuine notched case is too small to take a 6139B movement), though you often see 6139A watches in non-notched cases and with single-piece (all red) chrono hands.

… like this corker.

It’s a pretty unusual American market watch, a 6139-6007.

These were only ever made with a blue dial, and only for a few months it seems. This one came from January 1971, and has a 6139A movement and RESIST dial.

Nobody seems to know where or why the 6007 was sold; the –6000 range was never available in the US, but the –6009 was sold in 1970 with a 6139A movement, 2-piece chrono hand, a notched case and a RESIST dial. Ultimately, the –6005 replaced the –6009, and completed the transition to 6139B movement, so the –6007 is some kind of half-way house. The same dial and movement as the –6009, but the slightly larger case of the  –6005 and (probably) a 1-piece chronograph hand (though it’s hard to know as the 2-piece hands would often have been replaced during a previous service). All 6139-6007s seem to have an English/Spanish day wheel, so it’s possible it was intended for the Latin American market.


The lineage of the 600x appears to be:

6139-6000 – available in Japan (as a Speed Timer) with 6030TAD and 6030T dials, and in export markets with 6030T dials and 70M PROOF dial text. 6139A movement, notched case, 2-piece chrono hand. Early 1969 – mid 1970 (exactly when seems to vary depending on the dial colour).
Available only in blue & yellow in JDM and for export markets, and for Hong Kong market only, the rare 70M PROOF silver dial, with Chinese/English day wheels.

6139-6009 – effectively the American version of the –6000 – Seiko seem to use the last digit in the reference number to denote regional versions, such as the 6105-8119 in the US but –8110 elsewhere, ie the “Captain Willard”. Probably available late 69/early 70 until early 71. 6009T dial, RESIST, no-notch, 6139A movement and 2-piece chrono hand. Definitely only ever blue or yellow; there has never been a silver “2-line” (ie no “CHRONOGRAPH” text) 6139-600x.

6139-6001 – replaced the –6000 in overseas markets, 6030T dial, 6139A movement with 2-piece chrono hands, but non-notched case. It’s possible that the transition to 6139B movement and 1-piece chrono hand happened while still being marked as –6001. Available from mid 1970 until (possibly) early 1971; available in all 3 colours. All marked 70m RESIST (notice the transition from 70M to 70m when moving PROOF->RESIST)

6139-6007 – could be seen as the American equivalent of the 6001, but for some reason was only ever blue, and probably only from November 1970 to January 1971. All were marked 70m RESIST, the majority had 6139A movements though at least one 6139B exists and almost all have Spanish/English day wheels. It’s always possible that a day wheel has been transplanted during a service, and it’s also possible that a movement swap could have occurred at some point. I’m sticking to the rule that these are all for the Latin American market.

6139-6002 – replaced the transitional 6001 in early 1971; still marked 70m RESIST until mid/late 1972, then had no text at 9 o’clock. Both 6030T and 6030R dial variants were available in all 3 colours, RESIST and no-text, overlapping for a good portion of the time from 1972 – 1976 or so. Generally speaking, earlier watches are more likely to have 6030T dials and later ones 6030R, but there’s no hard rule. The very latest -6002 is 1977.

6139-6005 – the equivalent of the 6002 for the American market. Only says AUTOMATIC under the Seiko logo and was RESIST until mid 1972 then no text. Most if not all had 6009T dial codes; I’m dubious about 6009R as there are definitely fakes of that combination around, but have little experience with the 6005 variants as they don’t crop up in Europe very often. It’s reckoned that the -6005 was only made until 1973 at which point, maybe the -6002 took over for American sales.

The Seiko museum has no information to hand about the –6007, but I was hoping to solve the “where did the –6007 go on sale” conundrum with this watch, as it came with box and papers…


… but sadly, the purchase details were never filled out. Argh!


Seiko 6139-600x–part i – as worn by Francois Cevert & Nick Mason

50 years ago, Seiko was quietly producing what could arguably be the world’s first automatic chronograph. Other manufacturers were trying to do the same – Zenith produced their goadingly-named “El Primero” (a fabulous watch movement that was comparatively small but also beat at a higher rate than its competition – it went into other manufacturers’ products including the Rolex Daytona), while a consortium of others, loosely known as the Chronomatic Group was formed by Heuer, Breitling, and Hamilton, together with movement maker Buren and the company who could make the bolt-on chronograph module, Dubois-Depraz.

There are many articles online [here’s a good one, and a later one by the same author focusing on the Chronomatics] detailing just how one of the three contenders was actually the first but in truth, it doesn’t really matter. We could split hairs about what is important – being the first to announce, the earliest prototype, the first to sell in-market? Certainly, at the launch in New York of the Heuer Caliber 11 watches, March 3rd 1969, one lucky winner of a new watch found that it was less reliable than expected so maybe Heuer were jumping the gun a little.

Anyway, back to Seiko. It seems that it had quietly been selling watches in Japan with the 6139A movement dated from February 1969. Typical of Seiko, they produced a whole variety of case and dial styles with the 6139A from 1969-71, and then the 6139B until 1977-78.

I’m going to look at a couple of early bearing the 6139A, and belong to the 6000-family made famous by the association with NASA Astronaut Col. William Pogue, more of which later, when I’ll cover a couple of 6139Bs.

OK, enough preamble – let’s talk about a watch.

Blue 6139-6000 from June 1970, aka “Cevert”


This was bought from its first owner, who got it as an 18th-birthday present from his brother, who himself was serving in the Royal Navy in Singapore, in December 1970. On arrival with me, the watch was pretty tired-looking – and the bracelet had lost one of the correct end-links, so the previous owner had installed a different one that didn’t quite fit.

It has since been serviced and a replacement end-link from the bracelet was sourced from a collector in Australia. The chronograph hand has a crack, and the watchmaker who serviced it was worried that it might break when he was trying to re-install… and the correct, 2-piece chronograph hands for these are like hen’s teeth. After well over a year of looking, I’ve found another – but fortunately, this one went back together just about OK. Other than the Aussie end-link and a replacement crystal, it’s as original as they come.

An eagle-eyed enthusiast spotted photos of F1 legend Francois Cevert (whose untimely death was the catalyst for his mentor, Jackie Stewart, to launch his crusade on driver safety in motorsport) wearing a Blue 6139 in 1971… so this particular variant is being nicknamed “Cevert” (pr. seh-verr).

Pink Floyd’s Nick Mason had one too:

And eagle-eyed space fans might spot a blue 6139-600x on the wrist of actor Ed Harris, playing Gene Kranz in Apollo 13 (a detail that the props team on the film got a bit wrong, as Gene famously wore a Seiko 6119-8460… other actors in the film were seen with Omega Speedmasters, many with 1171 bracelets that didn’t appear until 1970 and only on the later Speedmasters that were not issued to NASA… still, let’s not get bogged down…)

Ed Harris as Gene Kranz 2

The Ed Harris watch in question looks to have minimal text under the SEIKO logo, so it’s probably a –6005, which would only say AUTOMATIC beneath the larger logo, rather than CHRONOGRAPH | AUTOMATIC. It also didn’t appear to have WATER 70m RESIST at 9 o’clock, which would date the watch to 1972 or later.

Ed Harris as Gene Kranz 3

You can identify the early 6139–6000s as they have a notch above the recessed crown, and were marked on the dial as being water proof to 70M. Later in 1970, Seiko changed to saying “WATER 70m RESIST” and after 1972, dropped that text altogether. There’s a very good Collectors Guide to the 6139-600x series which goes into more detail.

This particular 6139-6000 is in well-worn condition; the lume plots on the dial are starting to go a bit degraded, which on some watches lends them a pleasing yellow tinge but on these vintage Seikos, just goes mouldy-looking. It’s not too far gone to be ugly, though.
