Engineer and mechanical watch enthusiast here. I've lusted after this piece for years and finally bought it. 1000% worth it.

I am the original owner of a 1983 Seiko Quartz chronograph that survived a house fire with the mechanism just needing a new coil and cleaning. The construction and jeweling of that movement is amazing. It runs as well now as it did new. Not all quartz is the same.

Only Seiko has got the balls to pull this off. Well done to them.

4:10 was the best moment in watch reviews

Being a automatic, mechanical connoisseur, I now have two quartz movement watches. Seiko Premier Moon Phase and the Seiko SEBD003. For me it's now about accuracy and reliability.

The design and technology in the Tuna is ridiculous, no wonder you love it so much Jory. It looks great on your wrist (even though you generally like smaller watches). Thank you for another excellent video :)

Loved my Tuna when i worked on offshore oil rigs. Seiko and Victorinox make some of the toughest, meanest quartz watches out there that can take a beating day in and day out and still look and function great. Only watch snobs turn up their nose at a good quality quartz movement.

Jory, as always you make it fun! You make it informative! Thank you for all you do for our community of watch collectors! Especially us beginners!

Well done for REMINDING people that this watch is undeniably the best quartz diver in the world. Also I agree with you that it worths every penny. BTW I have the SBBN033 paired with a brushed-polished endmill. When you fiddle with it you will understand how robust and imposing this watch really is. Thumbs up !

I love you my man. Your enthusiasm for horology is contagious

4:09 That was funny! At least you didn't say Invicta!

Love your content. You helped me get into watch collecting

Loved learning about unique differences in 7c46 movement! (2:10-3:48) robust quartz mechanical efficiency via jeweled movement for quartz

This is so gonna be a gift to myself after I get PADI certified

I have a Seiko 7c43 diver, I gravitate toward this watch as my daily more so than my previous daily, the SKX. The 7c43 is similar to the 7c46 movement, both 7 jewels, antimagnetic, high torque serviceable quartz movement. I do prefer a sweep seconds hand, but nothing is easier than picking up my 7c43 and knowing it as the perfect time without having to wind it up every other 42hrs. Just my $0.02 Great vid

Nicely done!, I have the original Seiko TUNA 300m 7549-7010 made for Japanese market only S/N +++237!,I just had it completely serviced including the crystal replaced!, I’m lucky it still has the original band on it ( made in Japan), amazingly it’s more accurate than my grand Seiko’s!

Have one all thanks to you! And Love It! Keeper for sure

I love it! Ill be getting one ths year! Thanks mate.

Dude I love your sense of humour, brilliant videos plz keep it up ✌🏼👊🏼

Very interesting and informative! A good reminder that not all quartz watches are created equal.

Love this watch!!! Ive been wearing mine all summer on an uncle Seiko waffle band. Awesome review!! 👍

I love the enthusiasm!

I loved your review so much about this watch and purchased it Thanks iam very happy with it. I also have a grand seiko spring drive dive watch, crazy as it is iam wearing both at the ssme time.

Hi, 1st I would like to thank you for your amazing work! I am into Seiko watches and after owning an Arnie SNJ025 and other automatic ones; I have the plan to own the Seiko Tuna mm300. I am currently torn btw looking for the new SBBN045 or keep looking for a SBBN031 great used deal... What are you thoughts abt the new vs the old ones? which way should I go? ;) Thanks for your contagious energy and sharing your passion with us!

As I sit here wearing a mid 80's Lorus quartz diver, I have no issues with quartz movements. That said, I also appreciate my vintage mechanical watches as well. If the watch accomplishes the task for which you wear it (fashion, status, or god forbid... telling time), then that's all that really matters. Love your videos sir.

Those are killer watches. That quartz will tick in salt water... Even if a seal leaks. I have the daddy to this . The shc with a 7n36..22 years old. They work .

I got my first seiko - a world time - in 1969 from my dad in Bangkok. I bought a big tuna last year. Made totally in Japan. It’s fabulous.

May the quartz be with you.

4:09 “Oh, I'm..whrghwmmVOSTOK AMPHIBIA!!!“ 😂😂😂

The helium and nitrogen thing: under high pressure underwater, these gases start getting into the watch. When you come back up into regular pressure, the gases expand. This might damage the crystal or the movement. This watch has prevention and dispersion, which I assume means it is harder for the gases to get in and easier for them to get out.

Really enjoy your videos.

Cool you answered one of my questions earlier. Just curious what kind of problems Seiko encountered with Automatic Mechanical Watches for professional divers? I’m assuming jarring or being banged up against something that would loosen something could be one reason vs quartz.

Ordered mine from Amazon last night. 👊

Love, love, LOVE my SBBN031 Tuna!

I have got the SNBN015J, it is running for 6 years on it's og battery, great watch.

Nice Video is there a cheaper Tuna in Marine Master ? and does it have the same quality movement and craftmenship ? thank you

Great video. You got me curious about the movment in my Marathon TSAR Diver. It’s an ETA FO6 with 3 jewels, all brass, high torque, and serviceable. Quartz has its place. The biggest problem with quartz is that at some point that battery will need to be changed, while an automatic can work well past its recommended service point.

ive been watching your vlog and its very informative and had some humor... heheheheehehehe your not boring sir ...

Hey Time Teller Great review I have been eyeing this watch for awhile the one you are reviewing and seiko sbbn033 steel bezel look version with rubber strap ok so my question is how does this compare too Tag Heuer Aquaracer 300m Quartz Steel Bezel wich one has a better movement and quality and craftsmanship and lume ? for a gift how to hear from you soon Thank you TTT

Yaarrragghh Vostok Amphibia!

Try it with the Seiko silicon strap, you almost forget its there + it emphasises the retro style. Did you know there is a blue version? Nice info about the movement too, it is a special high torque piece.

What do you think about the sinn hydro ux which is also a really technically impressive quartz watch?

Hey, I was wondering if you guys could help , me with some suggestions about a watch I wanna get. It's the bambino open heart . It's on sale for like 160 and was wondering if I should pull the trigger or just save up for a better dress watch?thanks.

Cool video, very informative and short, thanks

Which do u prefer ..the 015 or 031? I like the overall looks of 031 except for the hour and minute hands

I bought one years ago. Great bang for the bucks. I’ve had Seikos since 1969.

I need your help sir. Does the case back on the seiko sbbn031 tuna have the date or year to change the battery etched on it somewhere? I’m looking at buying a tuna new but wondered if there’s a way to know what year it is before buying so I get the full 5 years out of the battery.

Hi Time Teller! Heard the new Seiko Tuna 2020 s23629 out with solar power movement! sapphire crystal anti - reflection! does that make this watch better toward perfect?

A sister (or brother?) model, I loved the SBBN033 I owned. Focusing on the quartz movement, some may not understand it, but the second hand ticking is perfect. What many quartz watches fail to that this does is it hits precisely on each tick mark AND there is no play each time it does it. There's just something precisely solid and perfectly ticking that the Tuna's quartz movement does. You really want a high-quality quartz movement in a tool watch over any automatic mechancial watch for ultimate durability and reliability. However, I am surprised you paid $1300 for the watch. I've seen new for around low $900's (on rubber strap) to about $1000 (on the bracelet). And, all Tuna's are essentially JDM, as far as I am aware, and thus unless you live in Japan, the warranty is no good anywhere else anyways so I think one could and should buy new or used for the best price they are willing to pay for new or used.

I have to say I have I lot off automatic watches but u sold me to get this watch..

Hey mate is there a reason you don't ever mention tissot? I've just seen there seastar 1000 and wondered what you make of it compared to the skx007

What do you think about steeldive SD1975 which is a Seiko tuna homage. People are loving it for what they are getting under 150 doller.

Hi Jory, I bought a sun019 Tuna kinetic and I absolutely love it. Sorry I’m not watch savvy and live watching your channel. Just wondering, does my watch have the same movement as you described in your video and did I pick up a decent watch?

Not bad this Seiko, but you are the star in this video🙌🏻

The SBBN033 is the most expensive watch in my collection, suprised myself being a lover of auto's

i love tuna. sad but true. i need this watch in my life

@thetimeteller Around 3:38 you mention the 7c46 is thermally compensated. From everything I can find on the net it is not. Just wondering where you got that info? The 9 series grand seiko quartz movements are but everything I’ve found says the 7c is not. Hoping I’m wrong.

Does this watch have instantaneous date change ?

I on the other hand am a nerd, however, I like to hike and go camping, free diving etc, but I am not extreme enough for such a robust watch. Something to aspire to... That's alot of watch!

Nice one, but I'll stick with my vintage skj kinetic for checking the box "Seiko and quarz"

what difference between this and the 9f in grand seiko?

I just bought one yesterday 😂😂

No hate on quartz watches here, I love over built watches hence owning a sinn u1 , btw if you ever want to review that i can send it out to you. but also love wearing my simple little casio duro . Great video as always , a pure watch enthusiast loves all types of watches whether it be 50 dollar duro quartz or a 8k rolex sub, of course he/ she doesn't have to like all but have a respect for all watches

How well do you like the kinetic seiko dive wTch

Love it!

OMG, you keep making me laugh. I loved this video. Your stage faces and voices are hilarious. I have both quartz and mechanical watches. They all have their place in my collection. ALTHOUGH.. the cost for this TUNA is high for a quartz watch even with all "Bells and Whistles." I am sure for someone it is worth it and I say, "Go for it!" For me? I'll put this Tuna between two slices of bread add mayo then feed it to my dog. All my current quartz watches are solar and atomic and that's MY requirements.

I wonder if Seiko could have modified a Mecha Quartz movement to also accomplish their requirements for this watch or are Mecha Quartz usually reserved for chronographs?

While most of my watches are automatic I do have a quartz Raymond Weil on order.. Tango Marshal Limited edition.. Couldnt help it the watch is just so pretty..

Quartz question Jory Casio Oceanus??? Do you know anything about its movement? Is it basically a G-shock movement?

Thanks for the review. Quartz lover here. The Tuna is nice but too big for me sadly. I don't dive but like a robust tool watch. I use the Citizen F150 movement in my Citizen Eco-Drive Promaster Satellite Wave GPS Watch CC3060-10E. It is "only" rated to 200m WR but It has similar new anti-magnetic and shock tech PLUS it knows where you are on the planet and sets the correct time, day and date...automatically. It has the new, high-efficiency Eco-Dive with 7-year power reserve. It tops things off with a sapphire crystal, auto-correcting hands and lume you can read a book by. All in a thinner, much more compact 43.5mm diameter steel case with a clean dial. It's the highest tech timepiece in my collection and my go-to travel watch. (which I actually do).

Tuna is a excellent piece! Quartz is the best choise if you want to do your job and nothing more....specially if you have a power reserve too! It does not loose time like mechanical watches....you dont need to wear it...you dont need to wear it under the light like eco drive watches.... You set the time....and the job is done! I have a citizen aqualand divers 200m quartz the last 10 years....perfect

Great to hear about the movement , am keen to get Sbbn027,

finnally an answer to my question

Sir can you please help me with Junkers Bauhaus or Junghans Max Bill? Can you make a video on it

You're the man!

From my understanding when a watch is subjected to saturation diving. Helium which is one of the gases used, can pass through the seals into the watch. Once the watch leaves the saturation environment the gas will remain inside the watch. If not vented through a pressure release valve. Its possible that the crystal will pop out as a diver ascends to the surface.

Thanks for making this video. Need some clarification... You mentioned "hardlex crystal" and "titanium alloy housing". Are these correct? I read the spec from www.seiko-watch.co.jp and it showed that it is with curved glass and stainless steel case. Could it be that there's an updated version? Tks!

Great watch!One day,maybe...

Thanks stimulus check 👌👌👌

Is there a upgrade tuna?

Curse you sir. I'm a day late and a dollar short and now I think I want one of these. Don't tar and feather me, but I've ordered a Chinese homage to see if I can put up with wearing this form factor. If I can, I'll sell off a few pieces, save a few $$ and buy the SBBN 031. I have a few automatics which I like quite a bit. But honestly, I mostly wear my Citizen Promasters. They are accurate as hell and maintenance-free. You now have me going down a rabbit hole of high-quality quartz movements!

Seiko watches are the best value for money. My father bought me my first Seiko in Bangkok in 1969. It was an automatic world time. It lasted until 1992 when the crystal cracked. it was so expensive to replace the crystal that I trashed it. Wish I had not done that. I bought a Big Tuna two years ago. What a great watch.

love you man, your born to have a youtube channel

Good ETA quartz movements in Longines watches, for example, are typically jeweled 6 or 7 or 8. Japanese quartz is not generally jeweled. Swiss jeweled quartz is the norm. And they are serviceable, if I'm correct. Regarding the Seiko: only Seiko has the capacity to service these, am I right? Just the opening process from the top is something very different.

Your thoughts on Grand Seiko Quartz .

I love to see the Tuna on your wrist, don't care if it is quartz. It match perfectly with your personality, but too big for my little wrist😅

What’s that poster behind you?

Thermo compensated? Is this movement yearly accurate?

My middle name is "Over-Engineering"....it's not at all actually, it's David, but I am getting a Tuna anyway and soon! Excellent Tuna video by you, Sir.

Hi Jory. Talk about a totally tool watch literally this Seiko. I like the Rolex sub but there's too much luxury (and expense) to really not want to take it off before a dive. This Seiko Tuna watch isn't cheap but not out of budget for a serious diver. Mechanical Swiss movements are too elegant for me to dive with. I would wear a Swiss mechanical to the office and use either this or a more budget friendly SKX for sports or diving. All luxury watches have their place unless you are astonishingly rich. Can't blame you for your love of this piece, especially for what it was actually designed for. Love you and Federico's videos. Thanks.

Mine gussl The new watch is great! I've praised its realism many times. I really recommend checking out their selection.

hello sir, it would really great if it a solar watch. really love it. cheers. :)

they have new tunas that are spring drive or automatic check it out on the Seiko Japan website

Well, I guess I’m part of the fraternity: I actually have a Breitling Colt quartz chronograph that’s even more expensive than the Seiko Tuna. Beautiful piece, super accurate (+/- 1 sec per month), more robust than most mechanical chronos. Obviously not for everyone, but it suits me.

Does anyone know why the Week Days are in white while Sautday is blue and Sunday is red?

Another interesting video. Big love from NYC! ☆Jonathane

Sir The Time Teller can you help me identify if my Seiko7549-7010 Tuna (or SBBN031 maybe) is Real or fake? where can i send you an image of it?

Wostok Amphibia!!! Ahahaha🤣

It would be cool if you compare your Tuna with a high end Citizen Promaster Ecozilla (Aqualand and/ or the 1000m) divers. Battle of the $1000+ oversized Japanese quartz divers.

I enjoyed the video but I'm definitely in the g shock does it better for less crowd
