This is the most beautiful watch I’ve ever seen, I’m lucky enough to own one. 😍

Wish someone would remake this strap design in FKM

Love these videos, they may be for a "niche" audience but I'm glad that you're taking the time to make them regardless.

Do people actually throw these away??

Nice video, thanks very much! :)

A very lovely timepiece. Thanks for sharing it.

Saw this today in Chinatown NYC and bought it! Brown dial with the bracelet. It's just such a cool design.

Great video, just purchased the same version!

Your speculation may be true. I have a Seiko daydate. It didn't have a piece of lint on the dial for the first few years. Then I noticed one. It made its way on the dial from some other location. No biggie. I removed it during a battery change.

The Roman "XII" on the Mark XII dial kind of doubles as a "12" and a "X-11" which is kind of cool

Do you have a video of changing the Darth tuna battery please?

from where did you purchase that German mesh bracelet?

It might be weird using a translator. If you have to pick one when comparing sbdx011 and sbbn025, which one do you recommend? I don't know English very well, but your video is very helpful.

I was interested in the Reissue with the ETA movement, and I had a question or three. So I contacted the customer service with my questions, that was about three or four weeks ago. I still haven`t heard one word from them, too bad for them, I do not think that I will spend my money on a CWC watch.

The Aquastar Benthos 500 is still relevant… for divers needing a timepiece that can track their dive time (with the bezel) AND their safety stops (with the chronograph). What sets the Aquastar Benthos 500 apart from other chronographs is that the pusher can be activated underwater without fear of flooding the case. Fortunately, Rick Marei has recently resurrected the Benthos 500 with the Benthos 500 Founder’s Edition. The dimensions are slightly thinner at the expense of water resistance (200m for the original 500m), but, hey, most recreational divers won’t be going beyond 200 FEET anyways! 🤿

When enthusiasts started calling shrouded Seikos “Tuna”? From which model?

Great video. Thanks

I had the same problem. There is a inner metal ring, the chapter ring goes underneath that ring. If you install it over that metal ring it will be loose and never will be able to fit on the dial.

Awesome watch…what are the case dimension?

Hard to believe this SUS 4S models and the original Alpinist 4S retail price were only $200 (Y30,000). Their current sports models w/ 28,800 bph are sold for well over $3,000.

I got ovw 110tdj only 9 usd in my country,it is in good condition working

my 6139-8050 has the same clasp as the Bullhead, which is very interesting because yours doesn't have it

Why a reissue? Just buy an original. I own a nearly mint 80s CWC. S B S diver...... Awesome timepiece! 👍

I had an automatic version but sold it and went with the quartz. The automatic version didn’t keep time well. But I didn’t have the dust issue. Or perhaps the tritium is flaking?

Good video. I had the SBBN029 (LE of 700) and sold it to help fund daughter's first car. Several months have gone by and I am on the hunt for the next Tuna as I miss it. Thinking of the SBBN025, Darth. I like both of yours and love Spring Drive.

When did the first first paint splatter GAT came out. Because I have an offer for the “2002 first edition” but I can’t find if that’s the true date

With the bezel being Cermet I'm wondering how it would be removed for service without shattering it. Have you sent the watch for service before / serviced it yourself?

Definitely a fun watch. Thanks for sharing.

one of my grails, such a unique watch.

excellent video, very interesting info!

How about a few shots of zoomed back a bit?

Very interesting piece indeed. I personally love the unpolished bezel. It gives a proper tool watch look. I love it, no gimmicks. Just you and the watch. ❤

I think it would have been helpful and appreciated if you had shown the entire watch on a bracelet or strap. Your video only provides part of the data for this watch.

Great video thank you for sharing. Recently stumbled across the quartz re-release of these, and while the colours are nice, the red S and the minute track of these keeps enticing me! Would be interested to know if you've found a bracelet that fits these as that's the main thing holding me back (although I realise that even if the end links fit, the difference in finishes might look weird).

I collect and own some lovely vintage seiko that I do not wear to keep them in nice condition, I wear a Lorus sports 100 Kinetic with an arabic dial similar to the model you showacase, I have worn this swimming and in steam/sauna rooms for over a decade and it has kept perfect time, I have owned SUS models and could not get on with the squared off hour hand, but I would like to find the model you have and see how I like it at some point, great review BTW with superb observations only a true connoisseur would understand.

What a great watch. I've been keeping an eye out for theses for several years, but if they do come up on eBay, they're quite expensive. Your previous video has been a great reference point. Thanks!

*Very absurd-looking watch yet very practical*

Beautiful tool

Any info on the case sizes of the Landmasters, thinking lug to lug. Thx

I finally got one a little over 1 month ago, after over a decade of lusting for one. Mine's a 2005 SBBN007 in really good condition (a little nicer than yours), but it cost me almost $900!! Even today the majority of these older models will have to be ordered from a seller in Japan. For just over 1 month, it's running exactly +1 second. Such an amazing watch! And this 007 model is my favorite of the Tunas due to the steel bezel insert, crop circles around the markers, white/silver day/date wheels, border around the day/date window, smaller Seiko and Professional script, and it doesn't say 'Marinemaster', which clutters the dial, imo. 👍❤

Debating on getting a brushed handset and black bezel insert for mine. I have the Darth SBBN013 and this one is still my favorite of the two. I love the crop circles most of all!

I love these.

Try using aftermarket straps from Garmin sport watch models. Fairly comfy straps at such a low price

I have 8 watches and this quartz is by far the most accurate. great video

Absolute legend, I have two sbbns in my collection one I wear one I bought in Singapore 2011 sbbn015 never worn still as the stickers on it little video on here love it 👌.

Love that watch and the black bezel insert

Living up to your channel name, good video.

Thank you for sharing! Even though this was produced in fewer numbers that the south pole it seems to be much more readily available online, although the optimistic prices sellers are putting these up for might have more to do with that than raw numbers.

both cool watches. of the two i prefer your first one.. the matt bezel is more legible for example. you make valid points re servicing and parts, no doubt. but the 6159 Grandfather Tuna is a killer watch. there’s nothing quite like that model.

these really are an interesting watch model. I hadn’t realised from images just how small they are until I’ve seen this vid just now. all the very best for the year ahead.
