I've bought this dang watch 6 times 

Just keep it.

Bruce, two words: Crafter Blue. Have a good one.

Solution is rubber strap, 95% of the time I wear mine on rubber

I'm thinking I may have put this idea in your head, but I've been in this same situation. I have found the Crafter Blue rubber strap really does transform this piece (to the point that I can wear it while I sleep). Even after purchasing a Black Bay, Seamaster, other Seikos, I still come back to the Marinemaster.

I've had 3 MM300s. If I get a 4th, I think I'll keep it off the bracelet and wear it on the original strap or a black Tropic. I wonder if that will help with the weight and give it more wrist time.

I have the 017, absolutely love it. The only thing, is that I switched the bracelet out for a strapcode hexad bracelet, helps with the top-heaviness and makes it far more comfy (and it looks better, too)

Dude..........I feel you man. I've owned 4 MM300's over the past 10 years. I love the watch but there was always something, I still don't know what, that caused me to end up flipping them. That was until I broke down and picked up the SNR029. This model scratched the itch perfectly, it's the ultimate MM300. Titanium, ceramic bezel, gorgeous applied markers, and the cherry on top......Spring Drive. My favorite alt strap on this model is an Erika's MN, so comfy. Loved seeing your journey with this model, enjoy the watch my friend!

I’ve always wanted a blue sla023 because I love everything about the dial and handset, but I could never pull the trigger due to the size dimensions of the case. And judging from your video, it definitely confirms the doubt the I have with the mm300’s. They are just too big for most people. I wear a blue bay 58 as my daily, and to me, it is the most comfortable diver that I’ve owned.

Bruce... I can relate. I love the Omega SMP300 and PO and have sold them both twice for different reasons. I always find myself missing them and once again I have purchased another SMP300...this time the NTTD 007 version. This will be my 3rd SMP300. My wife says I have a problem and I'm inclined to believe her. 😊 I think this time will be different...maybe. Definitely 1st world problems.

I’ve put an orange crafter blue on my SLA023 and it’s absolutely stunning, also got a strapcode Hexad to counteract the weight and it wears much better when I want it on a bracelet

Have you looked at the SNR029? It’s essentially a spring drive MM300 with a titanium case. The dial and hands look identical except for a power reserve meter and capped seconds hand. The PR hand is also capped. It was what finally convinced me to bite the bullet and spend more than 2k on a watch.

I own the SLA053 (the blue dial version) and I absolutely love it. To me it’s the prettiest MarineMaster Seiko has ever made. Plus I LOVE the black case. Plus I love the rubber strap on the black one. I have #19/500

On my second sla021, it’s perfectly imperfect! I love the lume, love the clasp, love the movement, love the bezel, it’s big, in charge. And it’s heavy on my 7 1/4 wrist but I wear it everyday! And now it’s soon to be discontinued! Bruce can you do a little investigation into this and what might be the next iteration?

Thanks for sharing Bruce. There were a few moments in the video I thought you were going to give up and end it and list it on eBay, lol

I bought an Iriomote Island MM300, and also did not like the bracelet. But when I added the strapcode jubilee, it became an instant keeper. Looks great, feels great, very balanced. Give it a try before selling!

I like the marine master but after having the same issue with wrist fatigue with my Tudor Black Bay Heritage I sold it for the 58. Much better size and weight for me. Then the SPB185 came out a few years back and I recently picked one up. Perfect size and weight for that one as well.

You might have reached the Jeff McMahon portion of your watch journey, Bruce!

Bruce, I understand it, but the reasons you specify for selling yours on, are the same reasons that keep me from buying one in the first place. Aside from a couple of novelty pieces, I do not have anything that big and likely never will. The one you have now is a stunner and if I was gonna buy one, that would be it! But, I would probably be content to have it sit in the watch box and only be worn occasionally. To continually be rebuying a watch would be disrupting to my mental health. But, maybe that's why you're Seicotic!? 🤣

got my sbdx017 (second gen version) several years ago. wasn't a fan of the bracelet and clasp. got an aftermarket bracelet that is thicker and heavier. that has balanced out the height and weight of it for a more enjoyable wearing experience

I can dig it. I think I'd put my money on a Golden Tuna though. 600m version, with that lovely titanium case. Light, accurate, and won't kill your wrist.

I'm on my 5th one. Started off with an SBDX017 but didn't like the mineral crystal and the bezel was easy to scratch. When the new models came out, I bought an SLA021 and then sold it for the reasons you mentioned. Regretted it, got another and then sold it. Got another 021 and traded that one off. Last summer I got the blue dial 023 and I'll just keep this one around. I don't wear it often due to the size, poor bracelet fit etc......but when I don't have one I'm always thinking about getting one. I heard a rumour these SLA021/023 have been discontinued. Any truth to that and do we know what's coming next?

Honestly the dial sold me on this one. It’s amazing. Can’t not look at it everyday 😂

It's ok to do this.. that's just the way you roll and part of the lifestyle. I've rebought a Seiko Tuna multiple times myself.. Pretty sure it's basically been at least 6 times, also. I think I finally found THE one this time with the SBBN043. And, there's a few other watch models I've repeatedly revisited in one form or another.

Just bought a new SLA and love it but the 8L35 isn’t winding on my wrist so I’ve got to get it serviced. 😢

I went Bruce’s route I bought marinemaster SLA021 then the higher end SLA039, then two more prospex LX watches and the issue was always the 44.5mm cases and I sold them all and now I got the 62MAS with 39.99mm and that’s what I will keep-, the issue is thickness and case size and less so the unregulated movement because we know mechanical watches never going to keep 2 seconds always.

I’ve recently got into dive watches . I love my orient saturation diver in red …A discontinued model now ..Bruce

I put the bracelet on mine back in the box and exclusively wear my MM on a rubber strap. It wears sooo much better and a really high quality rubber strap and I think I suits the look just fine too!

Mine is the Tuna. Have a quartz, have an automatic, have a spring drive…. And a baby tuna as well.

The best one you've had Definitely keep this One.

Ive had my MM300 for about 7 months...changed the bracelet because well,,,,seiko. But with the original clasp and better bracelet, it is an absolute king...a rubber strap then transforms the watch...it is just a great watch overall...it stands out from all other high end divers IMO

The blue one is the nicest blue colour of any dive watch in my opinion.

My Marinemaster is the Zimbe 7. I love it, but don’t often wear it because of all the reasons you just mentioned. It’s so heavy and unbalanced I just don’t enjoy wearing it. I’m much more comfortable wearing my SKX, Turtle, Monster, Willard etc.

I love mine and wear it on the strap most of the time. It is part of my rotation. Can’t beat the deep rich red.

I have the sla047 green dial and I love it been wearing it every day for a year it is slightly heavy and the clasp sucks unless you're actually diving, but I think it wears fine I also think it looks great in suit but that's just me lol

I know of someone who bought and sold a Sumo 9 times. I hope it goes double digit soon! I an early version, put it on a waffle strap, and it's a keeper. The Waffle strap makes it so the case isn't as top heavy. The bracelet quality is under the quality of the rest of the watch.

I hear you Bruce. I've purchased and sold or returned three Omegas. I'm transfixed by their elegance, but can't justify a "use case" for them.

The watch is a beauty so I don't blame you, on par with the Citizen Barnacle (I don't know which one I prefer between the two). Take this experience as a signal of this being a keeper. The cons are due the fact that is a truly profesional diver instead of being made for casual wear.

Seiko MM are simply the best and can’t be ignored by true collectors! ☝️🙌

I still have the green SLA019 version

The two tone marine master at timestamp 6:52, is that a render or a real model? If so what is the reference number on it? That is a really interesting color combo

“I think I’m set now” bahahah

@BruceWilliams I wear my SLA047 on an elasticized parachute nylon NATO and the fit, feel and look is perfect.

I love my SBDX017 on the rubber strap. I left the bracelet in the box.

Enjoy it while it lasts.

I just bought the sla055. It has all the looks of the Marinemaster but not the case thickness.

Is this a re-upload? I could swear I just watched this exact video like a month ago or so 🤔

have it love it … it’s my back up when I dive

Major Congratulations. Again 😆

I have to say that watch is something of a unicorn a really fat unicorn that must be experienced if possible. I have and I loved it and released it because of all the things you mentioned but it is still amazing no matter what. cheers

I’ve bought and sold at least 8 turtles, I always think I always want something ~better~ but it turns out I just want a basic turtle on my wrist.

Yeah, I agree bro. Are you okay?

Been thinking of getting a Marinemaster more and more. Never thought I’d drop 3k on a Seiko. Maybe an aftermarket bracelet would help?

You may have just bought the best one yet!

Have you owned a Spring Drive LX?

You are looking for happiness and completeness in a wristwatch. Good luck with that.

I bought my fifth Marinemaster a week ago... SBDX017 NOS. I hope I will not sell it this time.

Wow I never heard of the take that the watch isn't great to wear... I was really looking at an SBDX043 green MM300, but now I'm second guessing it

bruce! ive watched your journey with the mm300 ...i think this time,take the bracelet off ,strapcode it up,and then if you must flip it,the oem bracelet will be in brand new condition.But truthfully i think you should definetly keep this one!"

Wear it on weekends so you don’t have wrist fatigue

Another one? The definition of insanity 😂

MARINEMASTER even without movement I will buy it again😊

I still have the one I purchased from you. I use the silicone strap.

why set up behind an unplugged microphone

Reminds me of my wife. Too expensive and too large. Still keep comming back

Nothing wrong with a little crazy but I think you might have passed that on the 4th one. At least you acknowledge it.

I’ve owned 3 seiko sharks tooth alpinists and two pelagos. I get it dude. It’s a disease lol

Maybe it's not meant as a daily watch. Maybe it's just mean to be a great watch to take diving. And that's it. :)

That is an intriguing piece Bruce, but I do have a minor bone to pick with you!! Why do you constantly dog the first gen MM200's? They are premium, accurate, slim and comfortable and can be found at an amazing value of $650-$800. Add the MM300 clasp for under $100 and you have a premium watch that you can actually wear all week. These pieces hug the wrist and the lume is mind boggling, their old blue lume is unbeatable! My daily is the Pepsi SPB087 and I also have a SPB097 blue dawn, both are absolutely perfect in alignment including those premium bezels and run 1-2+ per day. I just don't want others to be turned off from such spectacular options. Finally the large unique hour hand becomes a much appreciated feature with aging eyes and brain. ✌️ Peace

ZIMBE Marine Master (SLA027) for Thai market, or the new Thailand-only monkey god model

You should try mm300 "hanuman" thailand LE.

What is this " Sell a watch" of which you speak??😆 If I sold one of mine and regretted it, I probably couldn't find another.

The watch has no problem. It is perfectly made for a purpose, and that purpose is immersion and not to be worn in everyday life. This is the problem with us, watch enthusiasts. We always buy watches that have nothing to do with our lifestyle, then we complain that they are too big or too heavy, when in fact we would be perfectly satisfied with any dresswatch plus a G Shock. I understand you perfectly.

After you sell this, buy an SLA055 or 057

The Marinemaster is really a tool watch for divers….it’s not really meant for every day wear . Even though it’s a great looking watch….

2:09 did you say mono cock case?😂 Seriously you should keep it, I bought the sla035 2 years ago and love it, one of the best dive watches I’ve ever seen

I can no afford 1 MM. Meanwhile my man here, throws away 5.

Mate you should get Certina 300 instead

This reflects that collecting is not rational and maybe a kind of addiction?

MM200 enough for me

Bought one, don't really like it 24/7, but I won't part with it.

“Fool me 6 times, shame on you. Cool me 7 or more times, shame on me.” Never re-purchase a watch you previously took out of your collection. You got rid of it for a reason.

Beautiful...I am not sure $3K beautiful. 🤔😄.

I've married and divorced the same girl 5 times...

Sell it to me!

Just swap bracelet for a rubber or Nato strap

Great handset but such a crappy bracelet for a $3000 watch 😢

I’ve never understood the hype with this watch. Built well. But it looks like a boy watch. There is usually something off with most Seiko dive watches. It’s really an ugly watch. There is no refinement for the money you pay. The bezel sounds like it’s falling apart when you turn it. The clasp is cheap. I’ve had the exact same clasp on a $400 quartz Seiko Velantura diver and it snapped in half at the bottom part of the folding clasp. Sounds like you’ve got a bad relationship with this watch. 😂 I would too.

Sell it and buy a MM200 😂

It sounds as if you have a learning disability with an inability to retain lessons learned.😄
