I can never quit this watch - REBUY NUMBER 5 

“I don’t know if I can let go of it." 😂 Ok Bruce. Good one.

Once a SeikoPath, always a SeikoPath... cracking piece... just wished they kept the lume pip on the bezel, I like that extra detail. Crank some LimpBizkit tonight and have a party with it! :)

I will stick with my 2004 SBDX001. Would never let go of it

I have an SLA047, the black/green Marinemaster, my first one and I saved and saved for it. Bruce, it’s not just you, there’s just something about these particular models! Good on you for finding that one and for just admitting you like it……it’s a badass watch dude! Enjoy it!

Congrats, Bruce. Beautiful. I have the Marine Master Tuna, quartz, and love it. It's +/- 1 second per month, which is flat out amazing. Enjoy your re-re-re-re-purchase. :)

From Seikopath to Seikopath: good decision. I made several rebuys but hope, that my SLA023 will stay forever. Love the watch

Your videos are really well done. Love learning about watches with them.

The 8L35 is one aspect that should always be highlighted, one of Seiko's best moviments, no plastic parts and Grand Seiko top quality level. Unfortunately we don't see this level of craftsmanship, parts quality and QC in many expensive Seikos in the Prospex, Presage etc lines using the 4r35 or 6r35 movements. In the 8L35 line they stated the range of +/- 10 seconds a day but I believe it's just a way of avoiding any legal issues, just for safety sakes. it's a damn accurate movement, as I was told and also information available online. Congrats for the purchase. Great videos. Keep uploading, man!!!! Wish I had a bigger wrist. Not for me.

Need one of those MM300 into my collection but for me the killer combo is the one for US only market...red dial baby !! Congrats for you rebuy Bruce and stay safe !

Awesome 😎 Bruce and congratulations 🍾🎉🎊🎈 on this amazing Marine Master 👍🏻

I see this as a "going on a summer holiday " piece, would look amazing in the sea or in the pool or going out in the evening .. seems to fit all situations. And it really pops!

That s a keeper.

The MM300 is your watch Bruce. Everytime you buy one you are so excited but then it you always flip...The MM300 is such a great watch and this one is beautiful 😊👍

I have the original "modern" marinemaster (SBDX001) in my collection since many years and I fully understand your crazyness about this watch. I have bought other dive watches since this one (in particular the very nice Omega seamaster 300 white ceramic you also have) but strangly no other dive watch have the same attraction on me. This watch is a real cult among real divers (I remember at the time when I bought it, I frequent some specialized dive watch forum and the marinemaster was as respected as the Rolex submariner by many). I quite agree with you: videos never render the beauty of this watch... you really need to have it in the metal to feel its quality and see the beauty of the finishing. I just regret the new version does not have the "marinemaster'" name on it ... just this sad prospect "X"

Man, I totaly can understand you, completely! This watch is a special one and in the time between buing some weeks ago and now, it becomes a part of my body! In the past, I´ve always look for a watch, that would fixed me, but all I can find was boring! Then I come up to this, seen this watch on so many videos over a longer time, but 3 weeks ago, I get one, told me, It´s the best I could get for my money! Polish, technik, bracelet, Saphireglas, Ceramicbazle, the enotmous weight and all the other parts are more than more you could not find on another watch in sthis pricerange, never! My black one is the best choise I could get! No blue, no green, black is the colour you should where, in my opinion! Black is the origin and that's the way it should be, everything else is nothing but fads. Thank you for let us see your minds! It´s my opinium, but still know, you will agree! Great video, thank you for uploding!

That is a really sharp looking watch! I'd love to see that MM300 alongside a 62 MAS homage like the SPB147.

Coming from Malaysia, man I was excited by this piece as Thailand seems to get all the cool releases. Still happily rocking my SBDX017 (Bruce may have played a part...) Awesome video Bruce and wear in good health :)

Fabulous watch I love it 👍 thanks Bruce good video

Hope you will keep it this time and wear it in good health. Absolutely stunning!

Yay! I’m awesome! Thanks, Bruce. You’re awesome too!

That insert needs a lume pip. I miss the old mm300 lune pip. It adds character to the watch

Saw a SLA045 for sale. Knew nothing about MM300s. Watched your review. On my wrist later that night. Thanks Bruce. Love your passion.

Superb piece, congrats!

That dial! Oh my it’s stunning.

Hey Bruce, really enjoyed the video, thanks. I would love to see this next to the LX, which is one of my favourite divers. Cheers from the UK!

Nice watch! The MM is awesome. I just picked up the Seigaiha SLA053. Love it

nice bruce, congrats! was thinking about pulling the trigger on a mm300 a few days ago but then sinn released the limited "103 classic 12" and i immediately had to go for this one instead of the mm300 :D this hobby is crazy! you think of getting a watch for a few days and then suddenly something else gets released and you throw all the money on that other option in a few seconds :D maybe i am more of an impulse buyer than a rebuyer :D allthough i already rebought a seiko turtle, a full metal square and a hamilton khaki field :D

love it B. also dig that high beat SLA25, super cool 😎 all the watches in that case really

Big thick chunky watch , looks great.

The best looking Marinemaster IMHO! Enjoy it!

Love seiko, just fricken love em.

Great review Rob. I love it! I can’t afford it, but love it.

Wow, this one is a keeper, please don't let it go. What a beautiful watch, but the price is a bit steep. Your videos are getting better and better each day.

Great video Bruce . The master looks a beast 👍

Immediately clicked the vid upon seing seiko in the title ☺️ Thanks Bruce!

I've really been getting into the higher end Seikos that aren't GS. Bought an SLA043 about a month ago and Im blown away by it

I knew it. And just when I was thinking of flipping my Marinemaster too. Looks like it will stay with me a bit longer. *edit* I'm with you on the handset Bruce. They're my favorite part of the watch and really the only reason I haven't flipped the watch. It's my all time favorite handset.

Rebuy 5 times?! Just keep it man.

Beautiful!

very passionate review, love it

I feel ya... I have an SLA019 (earlier LE MM300, seen briefly at 13:19) and it's my absolute favourite watch. This one is beautiful too :-)

I've never owned a Marine Master. I almost bought one but got a screamin' deal on a SLA 037 so opted for that . Great review Bruce . Nice peice.

Crazy in the correct way Bruce.

Got my MM300 a couple of months ago. Such an awesome watch. I get so many comments off people when I wear it.

Seiko rules. Especially the higher end ones. The Tuna is one more such gem which you love more and more once you start wearing it. And wears superbly on average sized wrists.

hey bruce, great review. finally pulled the trigger and got an mm300. but i really wanted the OG sbdx001, they are crazy expensive on the secondary market so i was able to source a NOS sbdx017 (second version). something about the purist in me wanted the text marine master on the dial instead of that prospex symbol. the alumium bezel insert and hardlex crystal are more retro too.

Wow, I think this is a sign! I just saw a green limited version at a local store. It's not too big as in the pictures. This is gonna be first in my list of next purchase, until it lasts that is.

LOL Totally get it, I'm tempted to go 3rd round myself personally!

I have the SLA047 with green dial. A True Masterpiece.❤

I agree 100% with Seiko removing the “Marinemaster” from the dial! Wish they hadn’t!

It’s a beast, currently saw the full black sla035 with red second hand it’s super dope, reminds me of Darth Vader and his light saber

Just when you thought you were out, they pull you back in again.

Great review Bruce!

It’s a beautiful timepiece but I sold mine. Owning one was a wonderful experience but I have recently downsized my Seiko collection from a dozen to just two. It’s so easy to get carried away in this hobby, I ended up keeping the JDM SBDX033 (all black MM300) and SBEC005 (Panda Chrono). Enjoy your SLA045!

I was still there 13mins in btw mate. Nice MM300 (even though I’d does not say it, stupidly) I have similar bracelet on my GS Diver with same clasp… don’t love it but I am used to it.

That is one good looking watch

Seiko Marine Master is a king of diver watches. Very good comment !!!

Bruce, you should send it back for service, so they can properly misalign the bezel! 😂 I'm just joking, this is a gorgeus watch. Enjoy it!

LOL…I think that you’re just addicted to the unboxing experience. Great looking watch, though.

There's a few aftermarket straps for these, some manufacturers do a waffle rubber strap with nicely fitted end, marries with the case perfectly. Probably a better more comfortable option than the stock bracelet.

I have a great local dealer that had the new Green special editions. I put this on, the MM200, Sumo, Samuari, old MM200, and new Shogun. I own a San Martin Sumo Homage, Omega Semaster, Tag link and a few others. The MM300 dial is soo good, the finish fantastic, the bracelet is good, its no Seamaster bracelet BUT its porportions just dont quite work its too thick. Make it 13mm and I'd be ordering it tomorrow

I have got my SLA045 today. Lucky me

Stunning piece! Too expensive though

Damn it Bruce, my pockets are not deep enough for this channel man 🤪

I can never quit seikos back in 2020 i bought my first seiko automatic the turtle padi pepsi and man i bought five more between presage japanese only model to transocean chronograph to marinemaster SLA021 then two grand seikos all i wear now is seiko i guess once you infected by seiko virus its hard to recover.

Great review. I've come close to purchasing the more affordable mm200.

Dat dial doe. I get it Bruce, I get it.

Awesome Intro!

It's Friday 🙂 Bruce has a new video 😀 It's a Marinemaster 😁

Bought 051/300 last week. My 2nd mm300 after the SLA047J.

Hey Bruce, I really appreciate the diversity u bring to your channel!

Starting the video with a shot of a dolphin taking a dump. Legendary!

Haha, you crack me up, Bruce! But awesome watch!

Good price for the watch, it is really nice.

You are crazy man. Just keep it this time, LOL. I have rebought the Sinn 104 once, and I have later bought watches that were sent in for presentation on my channel. So, I guess that is kind of like a re-buy?

You are not alone ! I fell in love with MM once I got the ocean blue SLA023 @ limited time 50% discount for AED 1.7K. I exchanged it with the Green SLA019 and paid USD 817 extra. It didn’t stop here..😀 while checking other models on RU-vid, I had a crush over this 🐬 and got it for USD 2.72K. I am still thinking 🤔 to add the Ocean Blue again, yet I am on the wishlist for a Tudor Pelagus MN22 FXD. What do you think 🤔?!

I give it 9 months-flipped!😎

Great pick and review! Really love the mix of colors and the texture and all the rest. And, yes, FOMO IS REAL AND A BITCH. I also say get yours while u can if even remotely interested. I pulled the trigger on that new Sinn 103 Classic 12.. not just of FOMO. BUT, it truly is a lovely chronograph and a little special for being their 60th anniversary.

Bruce, don’t fight your desires. Accept it, it’s okay to have more watches than you can practically wear

After the honeymoon phase, do a video with the MM300, the white Seamaster, and the Hulk. What a trio of divers!

Beautiful! I'm still not at the point of being able to spend this much for a seiko though. I just picked up a tudor glamour double date for $2650 and that context is just too glaring for me 😋

Seriously Brucemeister how do you do it a different watch every few days. 😂😉

Nice to see some effort put into the seconds hand. The standard gold ones look so rough around the edges. Seiko really needs to update that bracelet, the long links do look out of place and as you say - make for a mostly miss when it comes to fit.

I don’t understand when people whine and complain about “chunky-tall-heavy” etc in dive watches. It’s a DIVE watch for gods sake. That’s like complaining a Hummer Is too beefy

Thank Bruce by this video, I love marinemaster and I has SBDX017. The next one I able to buy ís SBDB021, what’s do you think about it, Bruce, please let’s me know your opinions.

Just keep them... I only have 18, including the SLA047.

The dial pattern is actually intended to resemble the intricate pattern of coral reefs.

Congrats on getting your rare keeper. Haha. That means this is the only mm300 left in your collection? I have always been fascinated by the monobloc case...

Does crafter blue not make a blue rubber fitted strap for the mm300? Looks like there’s only black, brown and orange available

I'm late to this video. But I'm considering picking up a MM. I have a Seiko sne497 (solar Tuna) which is my go to watch. If you are still considering a comparison video I'd be interested in seeing a comparison between the two. One of the things I love about the solar Tuna is how low profile it is. I know the MM is going be be thicker.

You have gone through many watches, but I will always associate the MM300 and the Rolex Air King Reference 116900 to you and your channel.

Sure, sure thing Bruce, it’s a keeper. It’ll be gone in 3 months! 😂

Best diver ever

I am enjoying both my green SLA019 as well as this Dolphin 🐬 SLA045 limited to 300. I am not sure 🤔 which one to keep. Any advise ? Is the green SLA019 released 2018 is considered an anniversary edition. Is it with to invest in the big box with knife 🔪 and get the SLA025 Hi Beat ?!

Just purchased the blue MM300. Do you think the Squale 1521 blue leather tan strap would look good on the blue MM300?

Good stuff! I just might. 🤔

How many times has Rolex changed the text on the submariner? No one really talks about it because it’s a sub. I would’ve loved the Marinemaster name but the watch has gotten better with time. The 300mm has an identity that is all it’s own. I’m glad I have 2 and that they still look timeless.

I had to experience a MM300 once, a SBDX001 which I did in 2019. Wore it for 60 plus days straight and sold it. Great watch but simply too heavy.

Beautiful and timeless Diver from Seiko! Love it. But I think it's WAY overprice for what you get. Yes, it's an upscale Seiko but it's more on the 'S' than 'GS' side if you ask me. Nevertheless I absolutely understand why you bought this, Bruce! If you really love a watch the price shouldn't be an issue (up to somewhat realistic limits, of course ;-)). Enjoy the 110! All the best from Germany

You mentioned about having trouble with the sizing. But doesn't this watch have micro adjust? And I am not talking about the dive extension.
