Great write-up, ewand. The chocolately brown is one variant I always look for on ebay and I saw that one being offered at $1,700 US. As you said, it is fascinating that it was never featured in a Seiko catalogue. Likewise, I assumed that it was a Hong Kong market watch because I have never seen one with anything other than the Chinese day wheel.

Just like to chime in about my Brown 6139-6010 has an August '69 serial, 6139A movement, WATER 70M PROOF marking on the dial and one-piece chrono hand (do not know if it was original or replaced at service). When it comes to the brown 6010s I've seen, I reckon it is nearly 50-50 in terms of having the one-piece or two-piece chrono.

I'm certain that all of these watches would originally have had 2-piece hands; since the 2-piece hand is deformed when it's fitted to the watch, I think it would have been seen as a service item and would routinely have been replaced, with a 1-piece hand.

So any PROOF 6139 watch with a 6139A movement that has a 1-piece hand, I'm fairly sure would have had it replaced in the past - the only exceptions could be the transitionals like the 6139-6001 where there might well have been factory cross-over.

Oh, here's my choco Bruce Lee on NOS bracelet that I found while it was away getting serviced...

It's got a nice halo around the subdial just like we see on yellow Pogues...

Beautiful, Ewand, though I'm disappointed to see the Chinese day wheel hiding! This and a blank-dial Silver remain the only real "holes" in my 6139 collection, and I'm afraid now they may be selling for too much for me to ever snag them...

  • bigbluekyle opined on the Silver 600x thread (here) that all the silver PROOF 6139-6000s (which, like the Brown 6010 was never featured in a catalog and is also rare), that Hong Kong distributor Thong Sia may have made a special order from the factory and had the watches delivered head-only, then matched to Seiko-branded Stelux bracelets ... especially the chiclet
I also am belatedly noticing this part of your post where you ascribe the (somewhat uninformed) guesses in the older thread regarding the brown -6000s to Kyle, but they were my opinions (as confirmed in the link). I still think I'm probably right, but the opinions are speculative enough that I wanted to make sure they're ascribed to me :).

If the Brown 6010 was indeed a special run for the Hong Kong market at behest of Thong Sia, I wonder how many were actually produced and the length of the production run. I purchased mine almost mistakenly and not because of the August '69 date.

Over in The Bruce Lee Seiko 6139-6010 thread, we had speculated that the earliest non-JDM 6010s were produced May '69 because Bruce Lee was wearing one by June '69. Then a member posted that he just acquired a HK market, blue dial on the Stelux 'chiclet' bracelet from March '69

I stumbled across a brown dial 4 or 5 years ago. Was actually my first ever mechanical watch, which was probably a bold move in hindsight. I bought an SKX007 soon after and also a Speedmaster Sapphire Sandwich.

The 6139 has not been out of the draw this past 3 years or so. Am deciding whether to move it on, but going to to a bit of proper research first. Torn between shifting a watch I don't use, versus regretting selling my first (slightly rash purchase) mechanical watch which does seem to have a very solid history. I don't even know if this is a good specimen - plenty of reading up for me to do.

Interesting - that's the first one I've seen dated 1970. Looks like quite a nice specimen!

Your watch looks to be in excellent condition, Pippo9. From the serial numbers of our respective watches, it looks like the brown 6010s were in production from at least August '69 to January '70. I believe I have seen a slightly later '70 as well, but am not certain because I did not save the picture from the auction.

Brown was such a '70s colour, I am curious as to why these did not catch on. I'm just speculating, but perhaps the total production run was less than a year. Thong Sia might have ordered quite a few because they pop up on ebay quite regularly.

Sixteen years ago I sold my one and only brown -6010. It was an October 1969 with a proof dial and Thai day wheel. I'd only ever owned one other watch with a Thai wheel. I've never been able to bond with the -601x as I liked the larger -600x much better. If I remember correctly I sold it on the old SCWF for only about $150. I do regret it now. So it goes...

In 1969 Muang Thong Co Ltd sold Seiko watches in Thailand. Muang Thong was part of the Thong Sia Watch Group. Seiko watches sold by Muang Thong in Thailand carried guarantee booklets that were nearly identical to the guarantee booklets that were sold by Thong Sia in other parts of Asia.

That's interesting - so Thong Sia might well have commissioned the brown 6010 for Hong Kong, but also shipped versions with Thai day wheel too?
I wonder if anyone's ever seen a silver PROOF 6139-6000 with Thai wheel...?

Hi all,

I splurged about a week ago on the pictured example (seller's very rough photos). A diamond in the rough, I hope... at over $600 in sort-of-running shape I don't think I won any "deal" awards, but it finally fills this niche in my collection and it certainly doesn't seem like they're going down in price anytime soon. One more in the "chinese day wheel" theory column, but no bracelet to confirm whether it was Stelux. I have a ton of parts and goodies in my stash and was sure I'd have an original 330W18GN crystal and an UncleSeiko railroad bracelet for this, but turns out I'm dry on both (but I have a whopping 10 original 320W10GN - aka 6105 crystals... should probably sell some of those). Anyway, parts are incoming now, and I'll post once I have it cleaned up and functional. Alas, I am probably stuck with those grimy hands - I don't think any donor ones would match the hue of that lume on the dial.

Forgive the terrible indoor photos but here is the one I picked up with a new crystal, a fresh service, and an UncleSeiko bracelet. No evidence one way or another on the Stelux theory, but it is another checkmark for the Chinese/English day wheel. It's not winning any beauty contests, and it's a shame I can't switch out those hands, but it certainly "scratches the itch" as they say.
