I have one and was amazed at how quickly I got used to the weight and size. I think being a bigger build helps the watch suit me fine despite smaller wrists. It looks like a solid man’s watch and not huge or crazy big like some of the watches out there. Mine is +1spd and has hardly left my wrist since I bought it. I actually sold off most of my watch collection and kept this and a GS springdrive along with a vintage omega. It was that good it stopped me wanting any other divers/sports watches.
That looks like one big, beautiful beast of a Seiko. Like a 007 on roids. Thing for me is, at that price, it’s a bit too ‘tool-tastic’. I think if I were spending my own cash I’d want something a bit smaller, a bit thinner, a bit more versatile. Still a great watch though! Hope Bruce keeps it this time. Lol. Edit: I JUST BOUGHT ONE (2024)
Seiko have some odd sauce in their large case watches - I've got this, plus the SBGA031, both theoretically big watches (43mm+) and yet, they fit really well, and they wear better than for example, the Seamaster Pro 300m from 2018 - I've got all three, and the Seikos wear nicer.
Definitely a nice watch the MM300. I would imagine since it has a relatively high-end Seiko movement, one which I believe they used to or a slightly downgraded Grand Seiko movement, it's one you'd most likely have to send directly to Seiko to service and perhaps in turn it may end up in Japan possibly.. unless they have a Seiko service center in the United States that handles these types of watches and their movements. Now would be a good time to get a MM300 since they are discontinued. Additionally, from what I've seen, all the new MM300's that are coming out will be even more expensive than this SBDX017 since they are all limited editions, as far as I can recall from Baselworld 2017.. not to mention a bunch of the other very nice, but also very expensive and limited edition watches from Seiko and Grand Seiko this year from Baselworld. For me.. I've got other watches that exceed $2k and encroach or exceed $3k mark I'd rather spend than the MM300. but, it is no doubt a great watch and will be a classic, as if the entire MM line hasn't been already.
Nice one Rob. I have this one, along with sumos, monsters, MMs etc. My bezel sticks a bit more than your one. I still love it. The lume is insane. It's not always easy to wear because it's bulky. But it's a keeper. Cheers
The sumo on a crafter blue strap is insane value. My friend with a breitling couldn’t believe how cheap it was when I showed him it. Equally the sarb035/33 is another Seiko that is phenomenal value although discontinued so prices going up
Or get an SBDC061/063. I purchased the 051 (the 62mas watch) and my friend purchased the 063. It looks similar to the marine master 300, but thinner, sapphire, 6r15 movement. I think I may like it more than my 051. Guess thats why they call the 061/063 the "baby marinemaster"
I'm not sure I could go with such a chunky watch. It's definitely sexy, and it looks like top notch quality, but it would be hard to imagine it would work for my wrist size. Thanks for sharing.
JustBlueFish Watch Reviews, I own a Seiko Sumo and it is surprising how well these watches wear. The fit a lot better than their size would suggest and very comfortable. The size is what it is but then theh give it a perfect tight fight by curving the lugs down and not making the lug to lug feel so long. It feels compact and hefty that it makes it feel like it is very high quality. Try a Sumo if you are not ok with spending the price of the MM300
The best value and bang for buck money, i prefer it to the new thousand dollar seiko divers, for only a thousand more you get so much more. Seiko realizes this too and soon they will discontinue the marinemaster and will hike the price of the replacement model.
Just picked one of these up and yes, Seiko’s best diver. Everything that is best about Seiko divers taken to the next level. Do wish they would make smaller case sizes but the 44mm still works with my 7” wrist, barely. I think the actual bezel is 42mm so it wears smaller? People call this model the Japanese Submariner. Being a huge fan of Rolex Sport watches and having owned many Submariners, I’d have to agree.
Nice watch, but much-MUCH rather have a Sinn U1 for $2,000 USD. I just have a number of issues with the MM300. Seconds hand doesn't match the min/hour hands' brushed surface, hate the Prospex "X" on the crown, and the bracelet clasp is very thick and causes problems when your hand rests on a desk/table/etc. And most MMs have hardlex, which is a joke above $500 these days. There is also a lot of cool things: crown at 4 o'clock, lume, bezel, power reserve, single case block, dia-shield coating, case polish. It's just at this price, I'd much rather go Sinn U1 or for a few hundred dollars more get a new Omega Seamaster ($2700 on Jomashop). I have a Monster and SBDC051 to scratch my Seiko itch.
Going to change hands for high prices now discontinued. On the downside. The U.K. concensus is that it stalled due to being £2900. So it'll be a few years before it gets classic status. New green bezeled (and dialed) version out soon. I think it's £3200 list in U.K. Yes, you go in from the front, same as the MM1000. I have a 1000MM your regional Seiko centre is armed to service.👍
Random Rob I would really love to have something that looks like a SKX007k2 but in like a 47mm case. The 42 just is too small for me but man I love the simple looks of them.
As big a Seiko fanboy as I am, I simply cannot justify the price of this watch and the lack of feature set to the competition. Hardlex (not sapphire) crystal, unregulated 8L35 4 Hz movement, lacquered (not ceramic) bezel insert, and a 20 mm bracelet width (the SKX is 22) for a 44 mm watch case is aesthetically unbalanced. I think it is a very attractive watch and know that people including Bruce love them. But for the same money I would rather spend it on 12 SKXes, or a Tuna and a Samurai and a Turtle. My hope is that when Seiko issues the new version of the MM300, they will address its feature shortcoming and can justify that price tag.
Charles Carroll if seiko regulated there movements like rolex then they would be very highly regarded imo, my 6r15 in my sarbs i owned were better than my divers for accuracy its a lottery
Hi Rob, You can check this link out. Once the bezel assembly is taken off (turn clockwise to unscrew it from the watch case), there is an opening on the watch case just slightly below/beside the date window. Press that level down inside it and it will release the stem from the movement. Hope this helps. www.tapatalk.com/groups/seikoholics/inside-seiko-s-sbdx001-marinemaster-300-meter-dive-t152.html
Tough question. More most I would say no doubt not do it. But for those that have done the journey and still want it then do it. For me I am happy with skx, monster, and turtle. I am hung up on the value of 200-500 dollar Watches.
Any qualified and reputable watchmaker can service this watch with no issues. It is not the only watch on the market which has an unconventional way of opening to get to the movement and I checked with my watchmaker who's certified for the Swatch group brands, Rolex, AP, Seiko, Lange, etc and they told me that they have had several in for service over the last few years. But you said it has a hardlex crystal, Rob, to me it looked like a sapphire crystal with blue AR coating. The way it plays with the light. I haven't checked it online but at least to me it looked like sapphire and if I am not wrong, here in Europe it comes with a Sapphire as standard. Please take that with a pinch of salt, but I am quite sure I read that when I was looking to buy one a year back. Please correct me if I am wrong.
John Doe I think it has to do with its size and shape which make it aesthetically pleasing plus its low cost and non hacking and hand winding (who needs these things) makes it the ultimate tool watch. You don’t feel ashamed of it for being a “lower end” watch yet you can be truly confident wearing it. It’s the perfect balance.
Lovely watch but IMO and as I recently commented on one of Bruce's reviews, Seiko's don't defy physics and are too large unless you're a Seiko fanboy of course. If any other manufacturer produced a majority of their watches in these dimensions they'd be ridiculed. As stated though... it's a lovely watch and your channel is great😊 And this is coming from a bloke with 8.25" wrists...
Might I suggest using gloves when shooting your videos? The pieces are always showing fingerprints which takes away from being able to see the lines of the piece.
I had my MM300 serviced by Jack at IWW however he no longet services them. The Seiko service center in New Jersey can service them other wise Japan is an option as well. Motor city watch works can also service them. I was quated 350 including round trip shiping.
I just picked up the Seiko bracelet for My SBDC 053 at it has really filled my itch for the MM 300. The 053 is perfect in my opinion absolutely love the watch.
It is very handsome and corrects many of the problems I have with Seiko divers, BUT, 20mm is far too narrow a bracelet for a 44mm watch. It should definitely be 22mm. I said the same thing about the Sea Dweller Deepsea. I am glad that this year they up-sized the bracelet on that one to 22mm.
I don't think a Seiko collection can be complete without having a Marinemaster.
Shipmate true
If funds would allow, I’d get one even tho it would be pretty big for me. My wrist size ranges from 6-6.5 inches
Problem is its too expensive to be a 'seiko'.many people might feel they should skip this step and save for a GS or luxury swiss watches.
I guess Im quite randomly asking but does anybody know a good site to watch new tv shows online?
@Arlo Ayaan Lately I have been using FlixZone. You can find it by googling :)

Nice video
One of the best watches out with a great heritage.
Definitely one of the Absolute Best Diver Watches in the World !!!! Bottom Line Awesome Quality !!!!!
I have the 001 and I absolutely love it, wears much smaller then expected.
Love to see the marine master in 40.
Me too, but have you tried one on? You may be surprised.
It wears a lot smaller than its size.
Amen
That looks like one big, beautiful beast of a Seiko.
Like a 007 on roids.

Wearing my SBDX001 as i watch this, brilliant watches. Brilliant fit and finish!
mike o connor waiting for my sbdx001 as I type this :)
@@ph69jbl Congrats mate, nice pick up!
My favorite watch under $2,000. Then the monster of course.
I need that f**king watch! It’s a grail for me. Not sure if I’d get it without the MM logo though

The overall best diver Seiko made..
Nice one Rob. I have this one, along with sumos, monsters, MMs etc. My bezel sticks a bit more than your one. I still love it. The lume is insane. It's not always easy to wear because it's bulky. But it's a keeper. Cheers
The Sumo is almost like a cheaper version of this watch if somebody wants something similar but cant afford the MM300.
Sumo is amazing value
The sumo on a crafter blue strap is insane value. My friend with a breitling couldn’t believe how cheap it was when I showed him it. Equally the sarb035/33 is another Seiko that is phenomenal value although discontinued so prices going up
Would recommend the Seiko SBDC051 for $650-800 (has 6R15 movement, sapphire crystal, nicer bezel, and dia-shield coating).
Or get an SBDC061/063. I purchased the 051 (the 62mas watch) and my friend purchased the 063. It looks similar to the marine master 300, but thinner, sapphire, 6r15 movement. I think I may like it more than my 051. Guess thats why they call the 061/063 the "baby marinemaster"
I absolutely love the look of the MM but I'm afraid of it looking weird on my 7 inch wrist
Wow man that’s just gorgeous 😁
A superlative watch, don't you think?
I'm not sure I could go with such a chunky watch. It's definitely sexy, and it looks like top notch quality, but it would be hard to imagine it would work for my wrist size. Thanks for sharing.
It wears really good for sure. Easy to wear with plus 7” wrist for sure
I wear one with a 6.5 inch wrist. Don’t be scared.

At 2k they are out of my range ... Great watch though.
Man I want one of these, but I havent been able to find any (even used) for anywhere near $2k. I guess the $1800 days are over.
Nice watch, but much-MUCH rather have a Sinn U1 for $2,000 USD. I just have a number of issues with the MM300. Seconds hand doesn't match the min/hour hands' brushed surface, hate the Prospex "X" on the crown, and the bracelet clasp is very thick and causes problems when your hand rests on a desk/table/etc. And most MMs have hardlex, which is a joke above $500 these days.

Yes, you go in from the front, same as the MM1000. I have a 1000MM your regional Seiko centre is armed to service.👍
That’s one on my list ! Beautiful! What is the biggest case size Seiko has that’s has this look ? I like bigger watches.
If you like the bigger models. Look at the sumo and “baby tuna” both are on the larger size and still wear amazing.
Random Rob thank you for the info. Is this one a 44mm?
Random Rob I would really love to have something that looks like a SKX007k2 but in like a 47mm case. The 42 just is too small for me but man I love the simple looks of them.

My hope is that when Seiko issues the new version of the MM300, they will address its feature shortcoming and can justify that price tag.
If you held one in your hand you would laugh uncontrollably at idea of 12 skxs bringing you the same level of enjoyment.
Amazing all out and out tool watch.
Such a nice watch.
I read these are not discontinued actually.
Pretty hard to get now hope seiko still making some hope to get one just sold off a bunch of watches to purchase a good one
Be patient, Seiko won’t let us down. I predict some cool new models for 2018 soon.
check out the SBDC051/053 models.
Charles Carroll if seiko regulated there movements like rolex then they would be very highly regarded imo, my 6r15 in my sarbs i owned were better than my divers for accuracy its a lottery
Charles Carroll As long as its fast thats good, I think most mechanicals take a settling period.
My sumo and shogun ran slow

Good info to know most reputable watchmaker can service.
Even in Europe it's hardlex.
The later newer versions comes with sapphire but than you also get the Prospex X on it.
Just got a deep blue turtle and got to say it feels huge. Might sell it off. Much prefer the skx size.
John Doe I think it has to do with its size and shape which make it aesthetically pleasing plus its low cost and non hacking and hand winding (who needs these things) makes it the ultimate tool watch. You don’t feel ashamed of it for being a “lower end” watch yet you can be truly confident wearing it. It’s the perfect balance.
100% think the skx is the perfect dive style watch for most of us. I will be doing few more vids on this topic.
Why Seiko don't make 40-42mm quality diver watches? Something in the range of $1000. Not talking about SKX, this is no quality diver...
Some says it is not discontinued, but if you check seiko japan official website, sbdx017 is not available ant longer.
Lovely watch but IMO and as I recently commented on one of Bruce's reviews, Seiko's don't defy physics and are too large unless you're a Seiko fanboy of course.

The lack of a sapphire crystal on a watch at this price point is muy ridiculouso.
Apparently there's now a San Martin homage of this. 😎
The fact that I was constantly made me aware I was wearing her... made me flip her
Why no sapphire?! Seiko, PLEASE!
I just wish Seiko would use Sapphire crysrals
No sapphire is a show stopper for me. Especially at this price point.
Didn’t even talk about clasp?
I want to buy it where can I buy it. Thanks
Great watch but too damn tall.
Can you mod it to a ceramic bezel hopefully not a dumb ? I’m a little green on modding and although I love watches.. I’m still learning
Everything is possible!
I thought it had a red part on the seconds hand
