Seiko vs Seiko “mm200 vs mm300”

Great comparison review. That MM300 is a beauty. It just looks like a true top notch no excuse dive watch.

[@1968jpy]

Rob I purchased the SPB105J1 from Exquisite time pieces today used but in new condition for only $485 . Should arrive on Tuesday. It will be awesome having the MM300 and MM200 👍🏻

[@davidparkinson2924]

I have the 200, literally have not worn any of my other watches since.. almost 6 months now. Love it.

[@roochmartinez102]

Absolutely! I have had my MM200 for a couple months now and cant remember the last time a watch got me so obsessed! That's cause it one of the more affordable watches in my collection. The MM300 is a legend but the more I collect the more I realize I love thinner divers and the MM300 is not that. The MM200 is nearly a perfect watch for me at least.

[@deanwaller8283]

Same here,only difference is I switched the bracelet out for a decent NATO,it looks incredible on

Rob, great video, let me tell you, because of you and Bruce I bought the SBDC063 and I am so happy for that, this is one of my best watches in my collection, congrats on your great work.

[@Snek03]

Can't think you enough for this video comparison Rob!! Very helpful! Thanks!!

[@RandomRobReviews]

Welcome

[@laikainspace1]

If the MM300 scores 100, the MM200 scores a solid 88. Considering the 300 is almost 4 x the $, the 200 is good buying. I own one 300 and five 200s if that tells you anything other than I have a problem with spending.

[@varanid9]

Five? FIVE??? Sheesh, I thought I was bad.

[@mcstarling07]

Have had both and the SLA021 is still in my watch box. The SBDC061 is a great buy, even when just comparing these two. The SLA021, for me, is just a step up in just about every way. Better bezel action, better crystal, better bezel insert, better dial and handset, finishing seems a touch better, I like the adjustable clasp (I enjoyed the 061 bracelet too), the cool factor of the monobloc case, and that wonderful 8L35B movement. I can understand a lot of people opting for the 061 and it's probably the smarter buy, but the 021 is just special.

[@7rslender]

I recently got an SBDX017 but I am still thinking over the SBDC061. Do you think there is a place for both in the same collection?

[@oldschoolebm666]

@@7rslender I'd say too similar...if you want another Seiko driver, I'd go with you tuna 300. That's what I did and I have two very different and iconic Seiko divers. MM300 and the tuna.

[@drwindsurf]

Thank you Rob, I have been wondering about the differences between these two. Both are awesome watches. Thank you so much for this video :)

[@Seikoholic1973]

Excellent review as always. My experience (own one) and my thoughts on the MM300 are: It is superior in every aspect, it follows the lineage of the 6159, wearing excitement, built like a tank so no need to worry about the elements of nature. It is simply a showstopper. Considering all the above it is a value for money compared to other Swiss brands.

[@laikainspace1]

Inspector totally agree

[@floofycatz]

I have the previous edition, with the non-sapphire crystal and painted bezel insert. I love it. I do want to jump up to the blue MM300 early next year.

[@RandomRobReviews]

[@galaga8834]

Very good comparison Rob. I have the SBDX017. The last of the true Marinemasters. I love this watch and prefer the bezel insert to the new ceramic version. I had the SBDC053 and sold it because it wore big and I just couldn’t warm to the handset.

[@LooptroopRocker]

Thank you for this video. I guess these are good problems to have but I own both atm and can't decide if I should sell the mm200 or keep it. Like you said, it wears a little better than the mm300 and for me personaly it has a better looking bracelet. It is the only thing making me keep it right now.

MM300: Still the best from Seiko

[@RandomRobReviews]

Bingo. We all want one, few will buy

[@jeremeymiller3406]

Have a 300 and it’s one of the most iconic seiko divers hands down but as you pointed out it is beefy and not the best everyday day recently bought a 200 for that purpose I also didn’t like the handset either so I bought some marine master hands to put on it problem solved! A slower beat movement theoretically means less wear and tear also a plus for an every day driver, although I rarely wear the same one twice in a week these retro inspired seikos have been dominating my wrist I paid 4 times as much for my mm300 but after seeing this 60 series it’s not 4 times as nice either way you can’t go wrong with any seiko really Especially these upper tier divers best fully in house diver IMO!

[@edteach3r]

The Marine Master is beguiling, but far beyond my affordability unfortunately.

[@TreenighetMaranata]

I ordered the Seiko Blue Ocean Dial MM300 SLA023J1 : ) In a few days i will have it! I like the depth that the dial has, and the blue dial makes it even more gorgeous! All watches that have shallow dials are in my eyes lifelessly boring to look at in comparison! I had it for 21 days now, and I enjoy the watch, it's the only watch I wear!

[@mtp1979]

Great comparison. I have tried them both and beside the price it's the thickness of the watches that made me choose for the MM200. It just wears must better on my smaller wrist. And my 6r15 is below +4s/day ! What's not to like about it. And if I was willing to go above 2.000 eur for a diver I would stretch it to get an Omega SMP 300 (the new one which is 42mm and the master coaxial chronometer movement).

[@varanid9]

Greatly prefer the 300. The thickness is iconic, while the smaller dial really channels its 'inner retro'. Almost got the 200 to go with my Marinemaster, but, the dial was just too damn wide. It's a nice watch, though, nevertheless. I chose the SBDC153 instead, but, found that that is also a little too "OH, LOOK AT ME!!" size-wise, so, flipped it.

[@bigjoel360]

I do read the stats....👍nice video, nice watches, nice everything. Hopefully they going to be on the Sunday sale!

[@RandomRobReviews]

Yup

[@shipmate3577]

I absolutely love my Seiko SLA021 marinemaster. I like it even more than my Rolex Submariner (ceramic no-date). I just like the hands and the deep/tall bezel. I dislike the SBDC061 because the handset does NOT match the indices... it's a dull, matte grey color while the indices look like polished metal.

[@mcstarling07]

The 051 is the same. I want to change out the handset and I think if you put some marine master hands on the 061 it would make it a real keeper.

[@Eu-ft8qj]

What’s your favourite Rob?

[@Justin-ml8id]

That MM300 is a stunner! Man if it were 39-40mm case with 13mm thick and down, I'd buy it in a heartbeat. What a cracking watch!

[@7rslender]

Did you try one on? I have a 6 inch wrist and it works for me.

[@TennesseeMike]

I read it. But if I need the detail I will just watch vid again. Or look it up myself. Good video. MM2 IMO a great choice.

[@ThePurple1968]

great review (I know, I'm late :) ). I like the MM200 better. The bracelet is the same, the diashield is the same, its just really the movement that you are paying for in the MM300, but you pay for that also with the excess thickness and weight. My order is in now for the MM200 as its a mature, rather then a new watch! - I'm just slow ...

[@keesketsers5866]

Just ordered the 200 today, comes in tomorrow. I chose the mm200 because it reminds me of my Omega Planet Ocean (42mm, 2500c) which I sold and miss very much. I hope it fills the same role the Omega did. The MM300 is a beast, but I was looking for a more affordable diver to compliment my higher end watches (not afraid to wreck this one, I'm sure thats almost impossible). Hopefully it won't disappoint. I have a not so good track record with Seiko's (accuracy wise).

[@ramshackled.2247]

Hello, are you satisfied?

[@paranormalskeptic3893]

I think the MM300 is amazing, don’t have one. But looks wise, I just prefer the way the MM200 looks. If someone didn’t tell me all the info about the movements, and prices, I just like the looks of the MM200 better. Not that the MM300 is ugly, just prefer the looks of the MM200.

[@varanid9]

One difference between getting one or the other is that the MM300 is best for those who specifically like its own personality that it has apart from the original 6159. The "MM200" is more for fans of the 6159 who can't or won't pay for that ungodly priced limited edition re-issue. Personally, I like both for the different reasons, so, it's not really a competition for me.

Get the 300m Tuna. It's cheaper, wears better, is thinner, is easier to service, and gives you all the functionality you will ever need. Only downside is the hardlex on the 300m which is questionably a downside as most people prefer the curved hardlex to the flat sapphire on the 1000m.

If you get it for the same price as a 300m tuna, you can always sell it for at least the same price, if not some profit, and get a 300m tuna down the road.

First again, watching for these way too much!!

[@RandomRobReviews]

Nailed it

[@onemoretime8045]

I'd take the MM300, especially the older SBDX017 model. The MM300 will be worth more down the road while the MM200 will only depreciate. If you don't like the MM300, sell it and get your money back, you won't be so lucky if you don't like the MM200. Only exception to this I see being is for those with wrists smaller than 7 inches as the size of the MM300 may be a tad too much. I will also say that the deviation in time dial up mentioned by Rob in this video is nowhere near representative of how these watches run. Expect an 8l35 to run near +8 seconds on average and a 6r15 to be closer to +15 with a lot more positional variance.

[@ab-surd]

I own both the MM300 SLA021 and the MM200 SPB083 "great blue hole". They most definitely can coexist in a collection, because they a have their own unique appearance. I love these watches, just as I do my SPB143 and SPB149. Now talk about similar watches. ;-)

[@henrywest7217]

Gosh, that is a beauty!

[@LonnieLawless]

I personally love love love the SLA019. The 300 is beautiful as well but there is something about the MM200 with the matte dial and the beautiful metallic blue bezel that makes me like that a bit more. The only thing I really like more on the 300 is that cool seconds hand.

[@highdesertforester]

I like the case and bezel of the MM200 better than its big brother but I much prefer the handset of the MM300. If I could swap out that handset I'd get the MM200.

[@varanid9]

I'd like to add, though, when service time comes, the MM300 needs to go back to the factory, where, with the "MM200", it would actually be much more cost effective, faster and more convenient to just buy a regulated NH35 movement and get your local watchmaker to pop it in, all for $150 or under.

Does the MM200 have a true 3 link bracelet or is it one link that looks like a 3 piece? The height / bracelet of the 300 turn me off, as does the spotty record of the 8L35 and servicing I look in the drop down box for extra info, links etc.

[@varanid9]

HEY!! How come there are no specs in the drop down beneath the video???

[@AhmadThabet-qw1kc]

Very good comparison and assessment made dear Rob, yet beneficial at the same time. If you are not a professional diver that you dive frequently then definitely go for the Baby Marine Master at 900 US $, rather than going to the Marine Master Professional at 2800 US $. The only differences are the signed Crown and the Accuracy of time from 0 to 1 Second compared to 5 Seconds per day.

[@warimoo1219]

I had the sbdc053 black previous version to the "mm200" lovely watch and i bought it instead of the sbdc063 at the time. Had it for nearly a year and loved it but in the back of my mind was the mm300 and has been for a couple of years but just couldn't bring myself to spend that on (a seiko!) Or so I thought!!! I now have the sla021, as soon as I saw this new version released and in black not green I something just clicked, yes it was a risk for me as no AD for this watch so it was boughh online but It came and just wow!!! A grail watch for sure that has written off many of the other so called luxury brands of choice in my mind. Tried a black bay, had a seamaster (one before latest) and believe me the seiko is in my humble opinion better, and although I love seiko I'm not a fan boy i just like what i like. So it was a big risk, but It paid off. Just awesome and pics/videos just dont do justice at all even side by side to another mid/high seiko like above.

Bezel action very good on both, lume very good on both( seiko still a little bit brighter even after hours) . The movement in the seiko is a rugged one and does it's job, but it is inferior in my opinion to the eta 2892 in the steinhart... Anyway I love them both...

The MM200 has a slightly longer case, lug-to-lug, but it works for me.
