Love the date window at 4:30!! Perfect colorway. Chef's kiss.

🤩 Great video. Thanks for spotting details others had missed and taking such HQ shots 🙏

The blue looks stunning! I may pull the trigger on that one

Good review! The “3 Days” on the dial is not necessary

Thanks for Sharing the new Seiko 👍

I much prefer the date placement on the new version. Looks great without cutting into the lume.

Thanks for the content. When I hear that music, I know it’s about to get good.

I got my sbdc053 for $670 US, 6years ago, still have it at the moment. At this current price point, lots of competition with better movement and less qc issues. I do give seiko credit for beautiful original designs but I hope they also focus on their qc issues.

I love the secret measurement “poink” sound lol 😅

Blue or black is a must for me

Thanks for the in-depth overview of these new Seiko 63MAS divers. They do look more refined and could have more comfort on the wrist.

Nice old vintage look,very good and nice watch

I have an SPB297 and i love It. These are very very nice, a definite improvement

That blue one is sweet! I’d probably go for the MM200 GMT first at this price point, but I’d love to pick up that blue 63MAS at some point

Thanks, nice review ! that date window , yikes

Love this series and can’t wait to get one!

I am looking forward to trying this on in person. I sold my SPB143, lovely watch but wore too large on my wrist. The SJE is just dang spendy or I'd go for that.

Good video and review! I like the new release.

The title says 63mas, perhaps you should fix that ;) On-topic: I got my SPB453 a couple of days ago and it is an improvement over the 143 in every way. The dial looks much cleaner with the added hour marker and the date window is barely noticeable. The '3 days' on the dial is unnecessary, but if you ask me, so is 'Chronometer Officially Certified', which uses much more dial space. The date and three days text seem to be a dealbreaker for many, and I can understand that these features seem prominent if you are only looking at pictures or macro shots. When you are actually handling the watch, you barely notice either. The bracelet and clasp still leave a lot to be desired at this price point so I cant wait for an aftermarket bracelet or perhaps I should just get an Artem sailcloth. Love the upgrades Seiko!

I really like your reviews always watch until the very end, very neat and detailed. Only one thing keeps me away from mid range 62 mas watches is 6R35 movement, with it's weird unpredictable accuracy. Hope they do well with this movement, and could finally compete with mid range Swiss 80 powermatic movement in terms of stability and accuracy.

Hi sir. I'm your fan. Please make a comparison video between bb58 & spb455. I have a bb 58. and just thought about buying this spb 455 because it looks more interesting with the case design and the color. Thanks a lot sir. ❤

If I was looking for a straight up dive watch the blue is very good.

So is the caseback essentially the same height but with a flat kanagawa wave logo? I also noticed the chamfered and polished bezel edge from earlier press shots, really helps to outline the watch.

Your reviews are always very detailed. Difference if any between spb239 and this new guilt model.

For me, the small round date window at 4:30 is a disqualifier. Thanks for your review. You always do a great job.

When they release the grey without the faux patina on a bracelet, as a true SPB143 replacement, I'll really be interested.

Great review as usual

have they managed to line up the bezels on this one? I have the 147 62MAS and the lume pip settles about .5 mm passed 12 o'clock - annoying

Great video. Really appreciate the detailed comparison and on-screen graphics!

These are so nice! Hard to decide between the special edition and the blue

Good details.

Thank you for doing this; very informative. Am I weird for liking the date aperture location and shape?😃

Great review.

I'm really liking the black and blue and not sure which I'd pick...definitely not the gilt though. I can't wait for that fad to disappear

I've had bad experience with the 6R35 and 6R54 movements. They just randomly decide to go out of spec (by a huge margin). I'm talking about one to two minutes off a day. I don't think I can trust this one either... So far the SLA models have been good to me, and one day I might try an SJE.

For that price you should get applied indexes.

Beautiful watch, especially in blue ! "3 days" on the dial can go, as well as "divers" Just "300 metres" would have looked better imo, preferrably in red (the non fading type of paint please :) ). Oh, and a red tipped second hand, now we're at it !

I own a Seiko LX titanium spring drive, Omega Seamaster, and Damasko dk32 submarine steel hardened case. The movement on the Seiko 63mas is satisfactory, but I am concerned about its accuracy. Anyway, great video

Good review! 👍

Ok. I have the SPB143 which I love. Great review . Do I need to this watch?????

Curious if the uncle seiko bracelet for my SPB147 would fit this. I’m sure someone will try it soon enough.

Thanks for the review! Agree the cheap stamped sheet metal bracelet extension has to go

Is the accuracy still horrible?

Definitely needed another low beat rate high dollar watch that’s almost identical to the previous ones they’ve put out.

I have ALL the iterations of the previous version, and have just got the SPB455. The very small changes to the watch head dimensions are surprisingly noticeable on the wrist, it does wear a little smaller, is a tad more comfortable on my 7.5" wrist and the bracelet is definitely an improvement. No mention on the Seiko website or your review of a 'super hard coating' on the case, I believe most of the the previous versions did. Any info on that?

Beautiful watch! Don’t understand all the hate.

I read the link about MEMS but it seems some portions were deleted? It doesn't state MEMS there

I have an SPB143. Do you think I "need" this one?. I love your video like always but I will love a more face to face video with the spb143... A battle?😂😂😂😂😂😂😂 Thank you very much for your review

이번 나온 제품중에서 포인트는 두꼐를 0.5 줄여지면서 디자인은 얇아지면서 오히려 방수 스펙은 200mm에서 300mm 으로 올려진점에서 좋은방향의 디자인 진보라 생각됩니다. 다이버지만 일상 생활에서 착용을 추구하는 디자인을 추구하는 방향으로 두께는 얇야지고 무게를 감소함으로써 착용감을 개선했다는 점에서 좋다고 생각합니다. 그리고 거기에에 방수 300mm 로 견딜수 있게 만들진점이 좋다고 생각됩니다. 차도 마찬가지로 엔진의 다운사이징을 만드는것 이 더 어렵다는걸 생각해봐야 할것 같습니다. 외형은 줄이면서 스펙을 늘리는 작업 쉽지많은 않다고 생각됩니다. 기존 SPB143 한국 가격이지만 206만원 거기에 이번 모델은 222만원으로 책정되었습니다. 불과 16만원 상승입니다. 만들어진 디자인 스펙에 비하면 과하지 않다고 생각됩니다.

Removing the 3 days, X logo & the date at 4:30, put it at 3 or just remove it at all

awesome vid

02:39 From this angle the hour marker does not align with the minute marker @ 1200 thats kinda biggie :(

Do Seiko offer any reasonably priced diver with ceramic bezel insert?

backward wiggle on the bezel still exist on this new version :(

I'm very tempted by these although I've heard that there's a 30th anniversary skx in the pipeline. I'm very interested learning the level of spec for this.

What SLA model is it in the beginning of the video??? It looks mostly like SLA073 but fully black dial with Marine master name right under Seiko logo... what could that be??? Please help to find exact ref!

The hour hands doesnt align perfectly with the marker😫, when the minute hits 60min mark the hour hand is a bit late by 1-2 minute.

2:38 Are the hands not both pointing exactly at 12?

Maybe the 3 days on the dial of this one refers to how often you have to set the time.

Hi, which one is better Seiko SPB451 or Longines Hydroconquest L3.781.4.96.6?

Beautiful watches in person. But yea, come on Seiko, the stamped clasp and diver extension remain awful!

I like your new visual setup very much. Congratulations 🎉

Thumbs up for your video. As with the subject of the video... I'm still not sold on the new 6R55 movement. And, your explanation that it is essentially the same as the previous 6R35 is not encouraging. The current state of the 6R movements and the poor clasp with ugly dive extension which is useless for nearly all of us as well as restricting good articulation of the bracelet to rest flat when placed on a table top all make me hold off from any Seiko dive watch purchases until they satisfactorily address both. I might have been inclined to spend significantly more to go with the new Marine Master with 6L movement. BUT, the same crappy clasp situation will hold me back. I want the COMPLETE package from Seiko divers. Plenty of other watches to enjoy until then... If that day will ever come.

I hate the round date aperture and its placement. A 6 o’clock or 3 o’clock date window would be fine. The 4:30 sucks

날짜창의 위치 변경은 이렇게 생각됩니다. ISO 인증을 위해 3시 방향의 작은 인덱스 야광을 개선하기 위해 4시 방향으로 빠지면서 3시 인덱스를 크기를 키움으로써 야광을 개선을 하다보니 부득이하게 4시 와 5시 사이로 위치를 바꾸었을거라 생각됩니다.

Ok I just checked the link for the proof picture and for some reason the watchmaker took down his photo's of the escape wheel and pallet fork. He posted last year in May and I thought it would always be up. No idea why he edited his post and deleted it. BUTTTTTTT you can see the 1st commenter saying, "Thanks for sharing. Precision part manufacturing to the tolerances seiko achieve with MEMS is amazing tech." One day when another watchmaker posts pics I'll update the link. sorry guys.

I wish I knew more about watches. A local jewelry store that I’ve been a patron for decades just started selling Seiko Prospex watches. The cheapest one is about $2400. But the Dillards at the mall has some a lot cheaper -$500-$700. The most expensive one on Seiko’s website is about $1000. I’ve looked at other places online too and found the same disparity. Why such a huge difference? What am I missing?

Gah! Just do a no date version already! 😂

Why the black dial is on strap only ? Is it available with bracelet ? Is it regulated or they just throw it at us with their atrocious -10/+25 ?

I still prefer the older model (only 1st gen as they dont have hideous lume on minute track at 3), i cant stand the date at 4.30 and what they brag about 3 days pr. Its a must buy for me if no date and just written “automatic 300m” cuz damn they look good. 😂

Very nice 😍😍😍

Price ain't the same anymore. The main questions here is, is it still worth it to buy a seiko, when you have a lot of microbrands with better value.

Are you even allowed to be a watch RU-vidr without that “A MAN AND HIS WATCH” book somewhere in every video?

This is only a small bump in price over the cheaper $1000 Citizen Promaster Fujitsubo Automatic diver watch. While that Citizen watch has a decent titanium bracelet it looks and feels cheap compared to this more expensive Seiko Watch. That gorgeous blue dial is what I really like with this Seiko diver watch. I would only buy one of these new these new Seiko 63MAS divers if I could get a decent discount.

Shock proof/resistant?....i need this kind of watch

I wish I could have one but I'm poor and can't have one but I'm still going to get a plastic watch 😢

So is the l2l 46.4, or 47.4?

Maybe they listened to me. 🤷🏻‍♂️ I've been complaining about that damn wave bump for years! It's irritating.

2:39 I have had a previous generation 63MAS with the same hand alignment issue. Seiko QC is just straight up laughable at this point.

The "62MAS Homage" link goes to a dead web page.

No. Date windows should either be at 3 or 6 o clock

I hate so much seiko because now I will spend money to buy it

Really nice background and setup, this is a good step up. But lose the gloves, c’mon man.

6 or 3 o’clock

It's a beautiful watch, but for me it's all about the movement, is the movement any good because the last one was trash

The old one is SPB147.

What’s with the falling titan name?

Nice watch but far too expensive - should be nearer £600-700.

Annoying they wont go with a date at 6 or just a no date variant. Btw does this still have a diashield coating that gives the metal a warmer hue?

Great looking watches! But... Pin and collar bracelet? For that price? I am getting way less of a Seikoholic by the day tbh. Latest Seiko-ish watches I have are all ugly builds from Aliexpress, and they give me just as much joy for about 1/15th of the price of a new Seiko. And that includes bracelets of the same or better quality should I opt for one. And those ugly builds still have mechanical movements of Seiko making, and I can swap them for about $30 the day they give up - if they ever do give up. As I wear a watch always, every day, year round, no matter the activity, I have come to a point in life where I all in a sudden do not wish to wear my SPB151 Willard as I know I will eventually destroy if against a rock, the underside of my car, at a construction site or by just being active outdoors doing "stuff". To me, Seiko has in a way lost a bit of its soul to the markets in a sense they are more and more opting to go expensive at the same time when makers like Steeldive, Seestern etc etc are cranking out watches in the $75-$300 range that are pretty much everything you could ever wish for both in looks and quality. Yes, sure they are rip offs but you still get stainless, sapphire, mechanical, and like I just said most of the time bracelets of similar or better quality.

To expensive, no signed crown and quality control issues will stop me buying this

Maledetta data

63?

Done with Seikos.

The blue is nice!!! Wish they did a ceramic bezel and lose the minute markers on the bezel and just keep them at every 5 mins. Overall they look good.

Fuck that date seriously

I’ll get a ball for that price

Owned a spb143 before and never again. The watch was pretty but wore heavy, movement sucked and bezel clicker broke. It was was replaced by the Baltic aquascaphe, and it's just better in every way for less $.

The only thing holding back Seiko watches now is the 6r series movement. Can’t wait for them to ditch it all and bring a 28.8k bph movement
