5126-6030
“The Double Hurricane!”

In June of 1969, Seiko issued a sales promotion brochure for its retailers in Japan entitled "1969 Summer SEIKO Ready Sports". In my opinion it is THE BIBLE for any serious collector of Japanese Sports watches of the late 1960s thru the early 70s. The dials, hands, cases and even bracelet designs are unique to that specific era.





http://walletfriendlywatchforum.com/FileStore/SeikoCatalogs/1969 Seiko Sport Diver Catalog.pdf

Most of the watches were offered in multiple variants. The 5126-6030 was no exception, available as it was in black and orange.



DOUBLE ROTATING BEZELS
The 5126-6030 has two rotating bezels: an external one, and an internal checkered bezel which is moved by twisting the crown.

I previously believed that Seiko’s only double-bezel watch was the 6119-6050 “REGATTA WATCH”. On that watch the two bezels were intended function as a way to keep track of the two stages of a yacht race.



However, I have found no documentation that the 5126-6030’s two rotating bezels were intended to serve this same function. Why have two bezels then? One plausible explanation is that this two-bezel configuration (not an uncommon feature of sports watches in the late 1960s) was meant to function as a poor man's GMT.



If you wanted to keep track of a different time zone, you could move the internal bezel so that you could see the other time quickly. For example, if you live in New York and want to keep track of the time in California, you can set the internal bezel so that it shows 9 o'clock when the main time shows 12 o'clock.

A blogger in Japan by the name of toto-zizi has dubbed the 5126-6030’s two-bezel configuration the "Double Hurricane Bezel" .「ダブルハリケーンベゼル」And so I now call the 5126-6030 The Double Hurricane!



THE BRACELET
The 5126-6030 Double Hurricane came with a comfortable and sturdy railroad-track style bracelet. It has three heavy-rounded links near the case, which gracefully taper to flatter links closer to the clasp. While this bracelet also came on the silver dialed 5126-8130, the way it lines up with the Double Hurricane 5126-6030’s case, and how it echos its curvature, strongly suggests that it was primarily designed to go with THIS watch.



THE 5126 MOVEMENT
From my perspective as a watch wearer, the 5126 movement is one of my favorites. It’s not exactly quickset, the date is set by pushing in the crown. To change the day you need to change the time from 9pm to 1am. But it doesn’t take as long as you’d think. Moreover the 5125 movement doesn't have the date alignment issues, nor the fragile plastic day and date fingers that that plague the 6106 and 6119 fifty years on.



I am no watchmaker, but of the finer aspects of the 5126 movement, The Watch Bloke writes:

"It’s an automatic winding, 23 jewel, 19,800bph movement with a day date complication. These weren’t produced for very long and consequently you don’t see them very often these days. The movement architecture is quite a departure from what Seiko was utilising in their other calibres, notably there’s no pawl and transmission wheel autowind components, and the keyless work looks quite different too. This calibre has more in common with the Swiss method of using reverser wheels to convert the rotors movement into winding the mainspring."

A RALLY DIVER?
Purists love to point out that what makes a REAL rally diver is the checkered bezel, period. If we accept this, than the 5126-6030 Double Hurricane is a rally diver on account of its checkered inner bezel.



But whatever you call it, the 5126-6030 Double Hurricane is a fun piece of late 60s style.

I love mine.

Thanks so much for the informative write-up. What truly lovely pieces these are ! Both the black face and the orange face seemed to me to be excellent candidates for the red two-piece center seconds hand, especially given the 1969 manufacture year. I wonder why they didnt receive it as a normal part of manufacture ? Oh man what a beautiful timepiece you have there in the before and after restoration picture. That sweetheart may have just moved to the top of my "MUST HAVE" list !

Thanks again for the eye opening article on the 5126-6030. I am sure it will become an important part of the vast history of Seiko here at SCWF !

These 5126's are very nice divers. The solid link original bracelets are really a nice hefty bracelet. I've had a couple of these for quite some time. They are both the black dial versions although I'd love to find an orange dial version.


I did observe an odd characteristic of the early 5126's. Some actually come with a blank day wheel. I've seen it on 5126-6030's of which one of mine has and also on the 5126-6010's. I'm curious as to how this came about. Was it the very early stages of including a day wheel?

That's weird. :confused:

I don't see how it's an early version of the 5126 though. The caseback looks like it's from 1969, and I have examples from 1968 that all have day wheels.

wow, that's the first time i've seen the black and orange 5126, i keep thinking
i want to be done with procuring any more watches, i have too many to wear
as it is now, but then i see one i know i'd have to think about if i saw it for sale....

come to think of it, you have this effect on me quite a bit, the kamen rider got
into my head, too, i am fixated on the idea of a minimalist rotating bezel, now.
and of course, most of our collection overlaps....

nice watches! .....but not rally divers =)

<* shark >>><
i dunno,

i think anything with a checkered rotating bezel is a rally diver,
that's how i'd define it, so these two definitely pass. i have a black
one and the checkered quality is very vivid.

how would you define a rally diver?
