SteelDive SD1975 Tuna Homage - PVD & SS - The Watcher 

Just received my SD1975 yesterday, bought in AliX summer sale. All green on the orange silicon band, looks fantastic, apparently flawless. Was worried it would be too big for 6.5” wrist, as it looks big on the desk but it wears small, love the rubber strap hugging it in nicely too. Wasn't a Seiko fanboy, bought it as a curiosity but loving it more every minute on the wrist, def a keeper.

I ordered ss version few days back! Building my own steeldive collection 😎 i just love them!

Because of this video... .I became convinced of the watch's quality...so I went ahead and bought one today! Thank you again for the great info and video!

I have this watch in stainless steel. No issues whatsoever.

Well after looking at a few more "Tuna" reviews I decided to have a look at one, I'd dismissed them because of their size but when I actually got one on my wrist I was pleasantly surprised, the compact lug length makes this watch sit so comfortably on my 7 inch wrist, it is a great looking watch, almost industrial, it has an "all business" look about it, fantastically robust. The fairly narrow ceramic bezel insert has a really great action, aligns precisely with not a hint of backlash in the mechanism. That wonderful dome of sapphire crystal with the blue glint of the AR coating is a perfect "window" to a very clear and easy to read dial. The three o' clock window has a crisp border around it and the white on black date looks completely at home on the classic black dial. Fit and finish are excellent at this price point. In fact the watch head would still be an incredible bargain if it came without a strap or bracelet for the modest asking price. Mine came on a 5 row engineer bracelet which is fine but deserves a milled clasp. Personally I'll replace it with something from Strap Code, probably keeping to the same very comfortable design. I think Steeldive do very well with their Seiko homages, they seem perhaps a touch better finished than some of their other watches in my limited experience. My "Captain Willard" is excellent and this seems very close (I'm really talking about the watch head here, bracelets are fine or ok, the watches deserve much better) The lume is outstanding as is the movement, Seiko's very own NH35A SII, truly a masterpiece capable of +/- 2 secs per day properly regulated. Reliable too. Another future classic if I'm not mistaken. Thanks for bringing this watch to my attention, the start of a beautiful friendship (the Tuna 😉) thanks to The Watcher👍🏻

Got mine last week....Very very good indeed. Faultless. And I wasn't expecting domed sapphire. Everything lines up too. Amazing.

I have this watch and it is a tank. It is my everyday watch that I can swim 🏊‍♀️ in. It is tough and always looks good no matter what. It allows me to save my Tissot for nice occasions.

Great video thanks. I came across Steeldive after my buddy showed me both his Seiko re-issue Captain Willard and the Steeldive dive homage. I don't know if he was just very unlucky with his Seiko but I know he was very disappointed with it and finished up returning it. The Steeldive was better in some ways. First of all there's the finish, while the Steeldive's brushing isn't of the same quality it's very easy to remedy. If you happy to to do a little bit of fettling or don't mind the slightly coarser finish the Steeldive is a very good bet. Personally I'd recommend purchasing from one of their UK distributors, as they give the watches a further QA examination, the ones I've seen from the UK supplier are more consistent plus there's no import fees to pay. My own Captain Willard is an excellent example, it's so comfortable to wear and of all my NH35A powered watches it keeps time really well, I set my watches weekly and it's never been more than +3 seconds out. That puts my Swiss movments to shame. The Tuna homage will be my next purchase, I've always liked the Tuna & the Turtle but a "real" Seiko is just more than I'd pay. The Steeldive alternative is a fantastic alternative, let's face it, your very likely to get a misaligned bezel with the Seiko and my buddy's was shocking on the timegrapher. (Captain Willard re-issue) Also there's no sapphire crystal and that lumed ceramic bezel on the Steeldive looks great. I know the bracelet on the SD1970 wasn't great, but again a little filing on the endlinks and a new milled clasp and it's serviceable, I expect to do a little cosmetic fettling with these watches but the watches deserve it and you end up with something that is such an incredible bargain.

My stainless steel version arrived yesterday, love it, bought from UK Steeldive site. Thank you for your videos

Mean aesthetics, great price, cant complain. Definitely next on my list, thanks my man👍

Got the black pvd Tuna three months ago. Wearing every day, pvd is top notch, it's like brand new form the box. I've put a black pvd steel bracelet. It's a blast!

I bought the blue dialled version with the Engineer style strap a couple of months ago. Great watch for the price, even my strap is comfortable and nicely made. Can't fault any of my Steeldives ( four so far ) for the money. Great video keep up the good work.

Hot damn look at that pvd version. Wow.

Just picked up the stainless steel version, and I love it. Just the pressed clasp lets it down. I will pick up a better clasp and change out. The watch is great wears well.

Respect to you my brother!! Again you got your finger on the pulse.... I been thinking about one of these for a while since ordering the Cap Willard few weks ago. You got me thinkinng about this one or a Proxima you reviewed with your new mobile phone website walk through of Tunas. That Champagn dial was sick bruv!! Suppose it depends if I want to stick to traditional look or go funky with the Proxima options. Once again great video, info and content!!

I have the Addiesdive with the sterile dial. It looks exactly the same as this SD. This is one of my favorite watches. I flipped the Willard, as the hands looked thin and short, small compared to the dial. I do not see any flaws in this tuna homage. I had the Heimdallr monster, which had so many sharp edges, a wobbly bezel, and a small minute hand. This is one of the best homages I found on AliX, along with Seestern. The lume is great, the hour markers are raised, the hands are legible and proportionate. I wonder if I would like it better with a steel bezel insert, and a flat crystal.. This is definitely a keeper. The deep black dial looks better to my eyes than the matte black Willard. Of course, it looks weird worn with a button-down long sleeve shirt, but great with a T-shirt. I wear it with an elastic black NATO strap with a thin yellow (or white) line in the middle and looks great, The bezel may be hard to turn when hands are wet.

Newest ones come with milled clasp with six adjustment holes. Got this one with black dial today. First Tuna homage. Fits my skinny wrist well. May order a titanium Heimdalr next. Good review.

Got the1970, now I must get one of those, good review thanks.

Great review! I have the PVD version and I put it on a black shark mesh strap. Stunning!

Great vids, thank you!!! I picked up the Steeldive SD1975 New Arrival 2020 Blue Dial Ceramic bezel.OH MY!!! It is beautiful. Waiting on the Addiedive MY-H8 1970 homage in blue (I like blue, what can I say?) Keep the videos coming!!!

I literally just heard of the SteelDive yesterday!

Got the blue and the black with orange accent Watchdives models on hexad style bracelets. Slightly larger hands than the SD1975. Have an all steel Heimdallr in transit. Would be good to see a comparison between these three brands .

That PVD version looks mean! Love the gloss effect too when its hitting the light, lovely watch!

Yeah buddy! Killin it! You keep showing the ones I’m curious about. I’m with ya man, we are a pretty good audience...😉...but you are keeping us here man so keep up the good work!

I'm seriously considering buying one of these and slapping a Seiko dial on it. I just want the classic tuna look with an automatic movement, I'm unsure why Seiko cant release one themselves.

You can pull off either for sure man!👍

I also bought a MAIKES after market Nylon strap with black pvd deployment clasp and full black leather backing. Very good looking, excellent quality, very comfortable. For about $20-25 on AliEx, to my recollection. Recommend.

Great video man, I'm another small wrist person and I think it looks great on your wrist.

I'll agree about inconsistencies. I bought one and the 5 and 6 o'clock lumed markers were off centre. I bought from a UK seller so swapped it but the bezel on the replacement is still a bit out. Maybe I'm looking too close but my orient mako cost the same and alignment is perfect. That aside, these are excellent reproductions of the Seiko they are based on.

Compre uno en Amazon por 170 dolares. Lo llevo usando 3 semana s y estoy muy satisfecho, sufre un adelanto semanal de 1-2 minutos minutos, de resto muy satisfecho con du calidad y lumens q son muy buenas para el precio.

It looks great in black, I have a San Martin ss but this one looks way better. I think I got the wrong one lol 😬

I just got the sterile Tuna today from Steeldive. It's not bad at all. Just a couple or so annoyances. 1. The Chapter ring is a fraction out. 2. The Lume isn't all it's cracked up to be on the reviews, as it soon fades within minutes to almost zero, The lume on my Padi Solar Tuna is far longer lasting. 3. The bezel cutaways on the shroud are pretty sharp. 4. The screw-down crown is a bit...meh. But for £100 it was a nice way to try out a Tuna as I was planing to buy the Seiko version. Now I've seen how one looks in the flesh, I will probably get a Doxa 300T instead.

Could not any of the PVD with rubber straps at the link you posted. I already have the black dial tuna with both the three link and the five link bracelets. I sized the five link for me and the three link for my son. We both really like it.

Gotta admit steel dive are the man at the moment...only San Martin probably better but more expensive...got 2 myself

yes a nice watch I got hold of a tsunami face and I love it glows very well and my I say I enjoy your videos very informative

Superb In depth Review Sir and I cannot knock the Steeldive Tuna as I have both the St/Steel version as you know and also the Simply Superb New Black PVD version with the Orange Dial and Bezel which I went for which is amazing (Must send you that one to review)I think you got the Red One. The Blue is also nice. Engineer Strapcode Homage Bracelet is Yes ok but I have a few Original Engineer 2 Strapcode Bracelets and you can see the Quality of Originals Compared to the Homage yet for the Money you cannot really complain. Apart from that I’m of the opinion Tunas look best on Rubber which they were made for. Top drawer Review Sir Well Done👏👏👏👏⌚️ I’m slowly getting through your back catalogue😜

At 18:25 does your SD1975 have the distinct ‘pop’ when you fill unscrew the crown? Mine doesn’t have much of a snap when it’s unscrewed. Seems like the spring is weak.

Did you do waterproof test, Unscrew it and check whether it has seal on winding shaft or if the watch backing has good seal too?

Thank you for the review thank you for directing me to your video remember I told I'm thinking of getting the SteelDive Black PVD Tuna Homage it's so tempting should go for it or wait for the one I really want Seiko Tuna Quartz 300m Black PVD ? Great review keep it up man on the videos ...

Really enjoying your videos !

I've now bought 3 steeldive, the green tuna the sumo and the fifty five.

Wow that looks like my sbbn 015 😀👍

PS: As for the Lume........ Mine luckily is also excellent. Lasts for ages !!

What you talked about around the 11min to 12 min mark about the click mechanism is totally wrong. You described the click spring first which is COMMON on most diver bezels. Omega Seamasters use the same click spring system. Rolex uses a slightly different one. Seikos use the same as Omega but with two raised bits instead of Omega's three. Chinese ones typically use two like Seikos. Other Chinese watches use the best design type which is holes drilled into the case with tiny 2mm diameter compression springs and a shaped end bit. There are also some Chinese diver bezels that use a third type which is the side mounted spring similar to what Steinhart and Rolex also does. Rolex GMT bidirectional click bezels are different yet but typically use the second two design types with shapes that allow for bidrectional rotation. The other thing you described is called the retainer spring. It's there to hold onto the bezel steel section. It's adjustable and if you pull some Vostoks apart you'll see the same thing. Seiko has it too... same with Omega... same with I'm sure half the diver bezels out there. This thin wire creates friction and is usually folded into an octagon if not more corners/edges up to 12. If your bezel is loose, usually it's because this retainer spring is not providing enough friction and the angles should be reduced - make the spring smaller. Vice versa. I get there are many watch noobs out there these days and beginners who I hope will continue to learn but all the material is online and worth learning over years. Have fun on your journey but it's good to set things straight. You can start by googling "bezel click spring" and "bezel retainer spring". There are maybe three common bezel mechanism designs and the cheapest and nastiest is the method used by Omega and Seiko. Execution is more important than design though! So finishing and assembly quality absolutely matters more. Here these inexpensive divers watches can be hit and miss. Then again Seikos have often been absolute dogshit and that's not even considering their pathetic alignments.

Gr8 video...thanks!

I will tell you what seiko must be shifting it. For the price and the quality which is well made I'd go for steeldive.

I really like this tune homages but I'm a bit unsure about the size. I saw some removing the outer bezel and made it smaller, does anyone happen to now what the dimensions would be ?

Great detailed review thanks . Liked and Subd

is it possible for you to show how the pvd coated watch would look like without the shroud?

Im having a really hard time picking between the black and stainless. What would you guys recommend? ps. I would take both if i could

Nice vid👍

Nice watches but they put on a horrible anti reflective coating which changes the dials colour

Would it fit on a 6.25-6.5 inch wrist?

Love the quality of the watches.... The water resistance thing is always in question… There’s never any mention of testing standards. 300 m? 200 m? I find it hard to believe...:

Awesome review mate thank you, just curious how you find the accuracy of the Seiko movements in these watches? Thanks!!!

I got the Addies version. Good too.

Steel dive steeldive bloody steeldive

The Black Tuna homage looks nice how's the quality In your own opinion ? Is it worth buying versus others its tempting for a beater if I do go for it first thing black nato strap or od green nato strap

Other than aesthetics and glare/reflection reduction in a military setting, is there any practical purpose to a PVD coating?

I have one nice watch but I think the shroud edges are a bit shape and the crown and the stem don't have a solid feel would be nice to hear if anyone has the same experience.

Can you pls review SD1978? Which is the big tuna...thinking about buying one)).Thanks

Great job once again! If interested I would happily trade my 1km Heimdaller tuna for the stainless Steeldive, unless you really want to mod it LoL!

Have a question related to all these homage style pieces. I own the steeldive 6105 and after 2 weeks noticed a scratch in the ceramic bezel. I’ve seen videos of people trying to scratch ceramic bezels on other none homage watches but nothing marked it. Yet I somehow have attained a scratch and I’m extremely careful with my watches. Would you be so brave to do a scratch test on the ceramic bezel? Is there maybe different levels of ceramic and steeldive get away with calling it ceramic but it’s maybe not as high quality as on let’s say original pieces? I also had a big issue with the crown but I guess this can happen with any piece. So for me so far, my first experience isn’t great in terms of qc but if you don’t have those issues then that’s great as the watch looks great. But the kudos for the design of course go to Seiko.

Finally, thank you. I want to order for the steel version with the engineer bracelet. Do you think the stock one is good enough or should I bite the bullet and get strapcode one?

Which is better the heimdallr tuna ss or the steeldive or addies tuna? Thank you

I've seen theese Steeldive Tunas with Great Wave off Kanagawa fully lumed dials on AliExpress which look fantastic but they are not on the Steeldive UK site so not sure if it's a mod someone is doing. I've only just bought the Steeldive Turtle with the blue dial but one of these is next.

What's the difference in price between the Seiko and the steeldive.

That SS Steeldive Tuna has a competitor in the form of the Merkur lower-end 'Sharkey' Tuna in the same range. The PVD Tuna looks nice enough. Both could not hold a candle to Uroborus though.

Nice video

Will skx007 bezel inserts fit on this?

Which one do you like better the steeldive or the San Martin?

Hey man do you sell the mouse pads ?

Is the loom radioactive.

I've never had a PVD watch does the coating chip or come off easy ?

You mentioned modding the stainless steel watch, what do you plan doing to it?

Guys just buy a baby tuna from seiko they are worth every penny not as good as the big tuna but still

Can't see the steeldive logo on the stainless steel version....how comes ?

What happened to your thumb? I know that hurt.

the truth is that who is going to be diving at 300 meters.. the world record is like 300 meters. you need hitrix to dive that deep ,. specialized equipment such as a special BC not to get sucked under unable to ascend and several tanks to control your ascend as to not get the bends and that may take several hours! you are talking about 1% of divers that will ever get that deep, most divers dive around 30 meters tops , anything over 50 and you are risking your life if you dont know what you are doing even a moderate case of narcosis can end you. Honestly what is funny to me is that most people could probably get a seiko 5 with 100 meters resistance and dive ok . 200 meters is probably ok for 99% of divers it amuses me when people stress about their watch not being 200 meters resistant with a screw in crown when most people may take their watch to a pool if even that. The Seiko tuna that can go 1000 meters is an absolute joke , the watch can go 1000 meters but you certainly cannot . that would be like building a car that can withstand a 1000 mph collision .. silly really but i understand the allure of over engineering .. it is just cool i suppose, but it makes the watch too damn big and bulky .

Just a question, how is this not illegal? I mean these are clones. I would assume seiko has to know about this, why haven't they sued for theft of IP?

Is this still a homage? 😂

WTF, i passed out and woke up you were still saying something about the watch. Don't dare to pick up the camera again.
