I for one lament the loss of the Marinemaster text

I prefer the look of the older tuna. Better hand set, better indices and I much prefer Marinemaster on the dial.

I still prefer the SBBN031. I prefer the handset, the signed crown, the “Marinemaster” text, the domed crystal and the stock bracelet. I modded my SBBN031 with a sapphire crystal from Crystal Times. Still, the new version is stunning...

Thanks for the great video, which addresses my desire to get a sapphire Tuna. Battery life is supposed to be 5 years, but I'm going on year 6 on my SBBN033. I prefer the more aggressive handset on the SBBN043. I wore my SBBN031 Tuna yesterday and the only flaw is that the tuna can doesn't conform to the wrist that well, nothing like the Captain Willard, but it's not a big deal. This new Tuna has to be a priority on my wish list. Thanks again.

I've stopped collecting watches for over a year. Now when I hear about watch prices it's like what the whiskey market is now.

Damn Rob, this is a beautiful watch, been on the fence about getting myself a tuna for a while and now that I see this one up close with the dark blue dial and sapphire crystal I decided to pull the trigger and placed an order from the same place you got yours, some viewers are bothered by the prospex logo, I don’t care about that it does not bother me at all, in the end it’s all subjective, great review comparison...

Thank you VERY much for this, been thinking about getting a Tuna again, this is very helpful, thank you!!

I think I still prefer the older design, though a flat sapphire makes a lot more practical sense. That domed hardlex was way too easy to scratch

All the updates look great. 👍

Looks amazing on your wrist! keep the blue strap! perf!

Very cool. Thank you for sharing this one Rob 😊👍

The domed hardlex on the 031 looks more “nautical “ in my opinion 😯

The Prospex logo and name are no substitute for the S and Marinemaster.

They begins using the 7C around the early 80s. So besides the new dials and finishes on these 300m tunas, nothing has been change in 40years. Same goes with the 1000M tunas, which saw even less of changes besides the coating and shroud.

this one will be one day my grail watch, I just love this watch so much

Watching this with my 031 on. Great vid, would love to add the new one later in the year.

Nice video Rob. Just ordered a SBBN031from Gnomon on Wednesday, crazy that they're sold out now.

Love both my tunas. SBBN017 and the LE JDM Golgo. The domed crystal to me is a must for a tuna.

Picked up the sbbn033 recently for £700, really happy with it at almost half the price of the new one. I prefer everything about the old model apart from the crystal personally, hopefully Seiko will put in one of the new crystals for me on the first battery change, will see how the hardlex holds up.

Cool video and congrats on the new Tuna Rob👏👏👏 I’m a fan of Tunas. I was lucky enough to nick name the Emperor, Blue Fin and Ninja Tunas 😎 That being said, IMO Seiko nailed the latest generation of 300m Tunas. Dial, hand set, crown and sapphire are perfect. Price, not so much. For that price Seiko should have reintroduced the SBBN015 bracelet. Having sold off my Emperor, Darth, SBBN007 and S23611J1 “Taiwan golden tuna”, I’m looking forward to ordering a new SBBN045. 🍻 Shannon

Much nicer - cleaner dial, lume looks better with the defined border, sapphire etc. I like the muted, deep blue they've chosen. People always complain about change, but they'll catch up eventually.

I like the new one a lot more than I thought I thought I would. I think it looks really good actually.

RR excellent review on the Tuna's which one would you go for and why ? and what make that one better ? I'm comparing and debating vs a Tag Heuer Aquaracer Quartz lightly used. thank you

Yeah boyeeeeee!!! Love the stepped dial of some of the newer ones. I have the Golgo Tuna. Flat dial. Want a used Tuna to rotate between my Turtles and Arnie.

I have the SBBN045 (black version). The bezel on mine is very smooth as well.

The new one looks really nice. Throw a Strapcode on it and it would be a perfect daily driver.

Prospex logo ruins a great looking watch 😬

Without doomed crystal looks somehow incomplete.

Was avoiding watching this video cause whenever I see something on the tuna, I want to buy another one. I had the previous gen blue Tuna SBBN037. Loved that watch and also got from Gnomon. But, I think it had slight flaws in it.. which was something I never experienced in an authentic new Tuna. 1) the second hand didn't hit every marker exactly. I'd say somewhere around the bottom half seemed like it started to go off a bit. 2) the bezel action wasn't consistent . The sound and tension changed about 1/4 of way through 360 rotation, off an on. Both of these weren't deal breakers. But, I do expect perfection from a Tuna if I'm to expect perfection from any Seiko diver. I'd love to get a new blue Tuna like what you have some day again. The price is a bit hard to swallow as they've gone up like around $300 over my last version. But, you know, despite the prices and hit or miss qc issues, ,it's easy to coax a reason to bite the bullet and swallow the bitter pill for cost of Seiko ownership.. the heart what the heart wants.. About the bezel. I also doubt it is ceramic. It looks like same kind of "liquid blue" they used in bezels of the sbdc053 and sbdc063.

I would love to own the Seiko Tuna because it's such a cool looking industrial watch but they're too big for my wrist. Now with the improvements, I'm shaking my fist at it. If Seiko were to ever make a 40 mm (which will never happen) id buy one ASAP. Rob you're banging out those vids and it's freakin Awesome. Thanks.

Since you like the tapering bracelet I recommend the z199 from uncle seiko. He has a new straight end z199 that I believe tapers down to 18 and seems to be less flashy than a traditional jubilee.

I think it would have been cool to compare this new tuna SBBN037. Anyway, what are the major differences Rob compared to the 037? I think you mentioned the crystal and the handset. Is the dial and bezel the same exact colors as the old?

I prefer the Marinemaster text but it does look good still, what I don't like is you get no bracelet yet you pay more money just with one upgrade sapphire. For the price of the new 300m can easily pickup sbbn025 1000m quartz tuna with sapphire crystal and ceramic shroud which is surely the better buy.

I wish they had this with the hi-beat. Seiko need to incorporate that movement more. Also, Rob, how does the fit and finishing compared to an Aquis? I wonder because really the price difference between the two would be the movement.

Wao... I might relook at 300m tuna again. Used to own some and don't like the difficulty of turning the bezel (hard to turn with wet hand) and the CRAZY reflection of the crystal (not readable when swimming in water). Used to own 1000m tuna also but too big and worry about battery change. This new 300m tuna might solve all the above.

The original quartz movement was the 7549 used from 78 to 86 it's been the 7c46 from 86.

7549 was the movement used in the first 300m tuna 1978. Was based on the 6309 automatic movement which most of the parts including the main plate which is the same. The 7C46 came out in late 80s which was the replacement not as good as the 7549 lots of plastic and composite parts.. Check out Spencer Klein on KZfaq he goes indepth with the 2

should I buy certina ds action diver or seiko diver watch?

Awesome vid, as always. I have three Tunas: SBBN031, 033, and 037 and would love to add one of these updated ones to my Seiko collection; maybe they’ll update the Ninja Tuna....! If I may make a recommendation for bracelet; check out Uncle Seiko’s beads of rice. I have one that’s generally on my Blue Tuna (SBBN037) and my goodness it’s gorgeous.

I'm hoping Seiko will come out with a black dial SBBN045 with a newer/updated bracelet.

In my experience the domed crystals are clearer in the water. I am not a huge fan of the domed crystals used in the Tuna's. I recently got a modded sbbn007 with a domes sapphire with blue ar. I had to chuck that turd and install an original hardlex so I can actually read the dial. We have serviced quite a few 7c46's. The battery life is suppose to be 5 years if I recall. But most of them seem to be right at 8 years on battery life. Maybe they have low consumption on batteries so that is why they last longer than stated? I am not sure. I think the 043 will be next on my list. Thanks Rob!

What was the flaw you found?

Hey Rob, can you let me know if your sbbn043 second hand ticks perfectly to each marker? Thank you Rob

I'm sure the bezel insert is aluminum, like the SBDC07X series. It looks very similar.

I got the old SBBN031 with scratched crystal. I wonder would it be possible to fit SBBN043 sapphire to it?

What time does the day change over on the 7C46 movement?

The original looks great and I had one but sold it because I hate quartz... If it had an auto movement it would have been a keeper. I still miss it but can't be doing with battery changes on diving watches. The seals man! :-/

Sir, do they make the new model with a metal band like the 031? thank you!

I think the answer is yes, but does the sbbn031 have a ceramic insert?

Prettier but lost some character. I do love the new crown. Much like the hesilite Speedmaster, on this Seiko I like it to be purpose designed.

What was the defect?

beautiful watch.

i would like to see the same 12 o'clock mark shape like the previous version

What's the flaw ?

I like both the handset and the dial of the new version better. The bars instead of dots on the old one give the dial a somewhat unbalanced and nervous effect in my opinion.

Beautiful

Cool serious diver. For that money, I expect a ceramic bezel. The loose action of the bezel is not such a big deal with the shroud. Is it made with a mono-block case? The Hexad will be perfect for that watch!

Yeah, if you want to take better photos, the flat crystal is a definite benefit. But it takes away some of the character of the watch, much more generic looking. The previous dial had multiple layers, which is more difficult and costly to align, but adds intrigue. Crown looks cheaper, and is. The elimination of the Marinemaster text...iconic to the Seiko high end diver watches...

Where can I buy the new one in black? Would you have a model number ? TY

Anybody know, can I use Sbbn031's bracelet with SBBN043? You I should wait upgraded Tuna version with bracelet?

I noticed that all the tuna's I've seen ,the second hand lines up with markers

The lack of reflection makes up for a lot. The domed stuff did nothing for me.

I have never liked the reflection on my sbbn031 crystal. Have you installed the new crystal yet? Which one did you order? Thank you

It's the perfect tool watch

Are the case & bezel dimensions of this new model exactly the same as the previous sbbn031? Cheers. 👍

Without the MARINEMASTER text it just isn't the same :(

prettyy sure domed on underside is for better depth. stronger

Dayum, my 031 tuna has been my favourite watch since I got it late last year, but man does that new refresh look amazing. All the updates make it look fantastic, my only niggle would be the prospex logo, would still prefer the marinemaster moniker. How do you get on with the Strapcode 22mm bracelets on the tuna, given the 21.5mm lugs Excellent video as always🖖

新型⌚がやっぱり良い❗

Why Seiko?

Rob, what was the flaw?

I really want to like the newer model but i dislike the hands and much prefer the ones on the former. It changes the entire aesthetic to me.

at least it lines up.

I prefer the SBBN031.

✌️😎✌️👌😎👌

7549 was first quartz in tuna

Damn QC 🤬

Yeah, I like the older one better

I think the thing that lost me was the flat crystal vs the dome, and the basic dial vs the beautiful stepped dial on the 031

Oh, if only this exact design was Automatic. Maybe 6R or 4R. Hell I even take 7S and mod the movement myself 😭

what's the issue with it not being ceramic? are you suggesting that seiko's enamel is cheaper and isn't as tough as ceramic?

Four years ago you could buy a Tuna for $995 w/bracelet. Today, it will cost $1,500. Only difference is sapphire crystal; it still uses the same quartz movement. Seiko, WTF?

IMO, the previous generation is vastly superior simply due to "MARINEMASTER PROFESSIONAL" on the dial. I have the last generation ninja tuna on a Strapcode Hexad bracelet, and it is by far my favorite watch.

looks like Beyblade

Really dislike that metal keeper on strap. I find they slip. Very annoying!

Sorry stick to my 015 marine matser ⌚🐟👌

Give me sapphire all day long. I have no idea how any of you likes hardlex better. It scratches if you sneeze near it

IT RATTLE BUDDY, MOST OF THEM. SHAME SEIKO, SHAME

I dunno why seiko is going to wrong direction. their quality is dropping bad.

For that price, I'd expected a signed crown

It's a fat watch

My bezel will turn if u look at it wrong and the crown is flimsy and wobbly this model sucks in my opinion seiko slipped on this one

I hate the looks of that cheap X

weird , bruce said the lume on the old one is way brighter than the new one.

I like the old design The new design is boring 🥱 Come on how much seiko paid you to over react so much on this new one ? It seems a fake review 🤥🤑🤑
