Looks superb!

And fantastic Lume too!

Thanks Karl, think I’ll have to go order one of these now!

I might have drastically culled the collection over the last 6-7 years, but I still have a couple of Tuna

6159-7010




7C46 - 7009

I have too many Seiko boxes (and too many Seikos) and mixed them up! Ironically I thought it was an SBBN045 but your post earlier in this thread made me realise that it was actually the S23629! ATB Jon

I know exactly how you feel.

I think the only real difference between the S23629 and the SBBN045 is the Kanji day wheel.

The SBBN043 is rather nice too. A direct replacement of the SBBN037.

Where's the canvas from Marty? Suits the watch

Tnx . Yes, I also think it is a great combo. Desert sand (german ww2 canvas) color in fact goes with anything I have tried it. Amazing.

Got it from diaboliqstraps (instagram and facebook) and the quality is top notch

Proxima Tuna mod with carbon and lume dial.

A couple of questions if I may?
What does the dial look like in daylight?
Where can I get one?
Where did you get a lume date wheel?
It looks really cool

Sure.

Daylight shot. The latter prior to a shroud change.

YouTube video of the actual watch:

It's a Dial Maker carbon and lume mix dial. I've never bought any of his products but you can Google him.

I think the Proxima Tuna comes with a lumed date wheel? I'm unsure but if not, you can Google it for more information as I bought the watch as it is now. Google really is your best friend.

Thanks for your comments.

[Sinnlover]

Sure....

Cheers I am off to have a google

Starting to play around with the strap options for my new-to-me SBBN025. Oddly, it’s quite a versatile watch. The shoulderless springbars are a bit of a fiddle, but it’s hard to see how you could possibly drill the lugs!

Three combinations strike me as particularly pleasing. First is more-or-less a standard for any tool watch in my collection: the Erika’s MN. I’ve got a black-and-white one which I think looks quite nice on the Tuna. It’s very comfy and doesn’t lift the watch head off the wrist too far (which is definitely a problem with a three-ring NATO). Because the watch isn’t too heavy it feels well balanced, too.





Next up is a grey canvas RIOS strap that wouldn’t fit in the lug gap of my Bremont world timer. I dug out a black PVD buckle, just because. The strap needs wearing in, but I think it works well with the Tuna and is sufficiently rugged-looking to work with the aesthetic.





When all’s said and done though, it’s hard to beat the original soft silicone rubber strap. It’s stretchy, flexible, flares into the case nicely and generally complements the watch beautifully. I suspect it will be on this, or possibly the dark green one from my Arnie, for most of the time - and largely on the MN otherwise.



I’ve fallen for this beast in a big way; something about the extreme functionalism of it really appeals to me. I’ve a sneaking suspicion it won’t be the last full-size Tuna I acquire.

Seiko Tuna Solar diver.

It wears and feels much smaller than its 47mm size due to the black shroud and lightness of the solar motor.

Nice thing though.

[Sinnlover]

Are these a tuna?
I think so, even if not they are a very under rated watch

Popped my 7549 on today
An eBay rescue that had been neglected - took me some while to locate a chapter ring for it

Looking good. A nice bit of patina going on too.

I have one of mine on today.

Nice watch but not a tuna in the true sense of the model. Only 200m water resistance for a start, good but not tuna standard. Adding a shroud to a diver does not a tuna make. Personally even the recently released solar tunas aren't tunas, tuna style yes, but not a true tuna.

Are they Official Tuna rules?

[martyloveswatches]

Yes. Shroud and 7C46 or 8L35

Or a 7549 surely?

Anyway this definitely counts

The 1000 metre Tunas really are spectacular watches - titanium, ceramic and a great movement combined to make a supreme tool watch. The fact they’ve been depth tested and failed at something like 3000 metres just shows how over engineered they are!

I always found a Seiko rubber was the best strap, I think partly because they flare out to c. 24mm at the lugs. I found a 22mm strap can look a bit weedy against the width of the case. But all those straps in your photos look fantastic! Tempted to try some new straps on mine...

Absolutely 7549 (forgot the good oldies)

Oops. I've just seen the post, above.

That's far too big for your skinny wrist.

[acg]

Don't care. Love it. :)

Doesn't feel much different to a 300m version tbh, not sure I'd want it any bigger though

Anyone tried the 43mm and 39mm models with the proper SS shrouds?

Gratuitous SBBN025 pic, partly to show off the lovely crisp new shroud screws (see “Mods and Wreckers” for that saga) but mainly because I checked it on WatchTracker today.

It has lost 0.4 seconds. In 56 days. Which implies an annual rate of about -3 seconds per YEAR. Time will tell of course, but for a non-thermocompensated workhorse movement I think that is mightily impressive.

I'm really smitten with some of these. Can I ask [1] whether there's any particular model which better suits the smaller, i.e. 7" wrist, and - since I'm feeling some inevitability about the outcome of perusing this thread - [2] which are the best online UK outlets? ...

I had and still have baby tunas, 300m tunas, 1000m darth tunas and Indont know any big watch which can be worn on every possible wrist (short L2L) like tuna-can can. If you have 7" wrist, get the one you like the most...warning, addiction allert when getting one!

Oddly I would suggest one of the 1,000m ones without lugs - the lug-to-lug on my Darth is about 40mm, which is one of the reasons it is so comfortable IMO.

[martyloveswatches]

When tuna and alpinist have sex you get a fieldmaster tuna. Purist will say it is not a true tuna but finally I managed to get a 6R15 inside a shroud
