Seiko MarineMaster 300 Long Term Review

[@pistolpete023]

I think you're the first reviewer of the MM300 who has actually dived with the watch. Nice!

[@mr.ethings1545]

Well I have never seen another diver with one that is for sure! I met a guy on a dive that told me he had one but left it at home hahah. Thanks for watching! I just posted a video about how divers use their dive watches using the MarineMaster! You should check it out if you want! I hope you like it!

[@pistolpete023]

@@mr.ethings1545 What is the most common watch or brand you've seen on dives?

[@mr.ethings1545]

@@pistolpete023 Honestly, I havent seen many divers wearing watches as the trend seems to be wearing Dive Computers that can double as wrist watches. The machanical watch that I see most often though are Seiko SKXs for sure. Most of the people that work the dive boats usually wear casio/gshocks as well.

[@Andarilho1974]

If I had one of these, I'd take it off when I washed my hand. So it doesn't get wet. And in fact sea salt or chlorine from the pool can dry out the sealing ring after a lot of use.​@@Abdullah-ou7bp

[@zacharyparis]

I much prefer pin and collar. You are only going to adjust the bracelet once. It’s more secure and more integrated with the bracelet. Screws are a pain, can get stripped, can come loose, and look stupid.

[@mr.ethings1545]

I agree! Aesthetically I like the look of screws (but its a double edge sward because if the screws are all scratched up they look horrible) but I have never had a pin and collar come loose where I have definitely had a screw back out unfortunately.

[@1968jpy]

I also agree with you. The pin and collar system is superior.

[@SirBigzalot]

Just purchased a LTD ED 140 year anniversary one. Have to say this is the best review I’ve seen yet. Hope you’re still enjoying yours.

I got the same watch as you . I’ve had mine about a month and absolutely blown away by the quality. It’s amazing 🤩

​@@1968jpyjust got my SLA047J1. Yes, I know it's late I the day, but I got it new from a reputable bricks&mortar store. It's a beautiful piece but I wish Seiko had not done away with the MarineMaster on the dial.

[@jeffd3802]

So excited. I've owned most divers from 50-5000.00. Finally have the sla047 incoming Friday. I couldn't believe getting it for half off and it's used unworn. Cannot wait.

Awesome! I hope you are enjoying it as much as I have enjoyed mine!! Nice to see they added the lume at the 3'o'clock too!

[@mr.ethings1545]

I agree! I heard that they came out with a new version in which they made it thinner by removing the monocoque case and lowered the rating to only 200 meters but the added the Marine Master name -_-

[@JLUnit416]

I doubt you remember, but I commented on your Marathon video a couple of years ago, which was instrumental in my purchase of it. I've come full circle and added an SLA023 to my collection, with the updated shoehorned, 3 o'clock lume pip. Still in the honeymoon phase, but I feel like it entered my collection at the right time. I don't think I could have appreciated it a few years ago

[@1968jpy]

I just recently added the SLA047 a few weeks ago. I waited years to be able to purchase this watch . To me nothing compares to this watch .

[@mr.ethings1545]

Hey man! Sorry I dont man this channel as much as I did back then! Glad to hear you are enjoying your SLA023! I have since sold the Marathon, not that it wasnt good but just because I wasn't using it, but still have my MM300. I dont think I would ever sell it as it means a lot to me! It really gets the balance of being a tool watch but at the same time having the class and build quality to be heirloom level!

Great review, I own the blue version of this watch and love it. Nice to see someone actually diving with it! As for the lume at 3 I guess your wish was granted with the limited green SLA047J1 2021, and probably following models…

[@mr.ethings1545]

The blue version is really nice too! I noticed that too on the new watch they added a lumed marker at the 3'o'clock, but I also noticed that the marker is pushed into the chapter ring so it makes the watch look less balanced but its nice to see Seiko trying to improve their designs!

I purchased this watch about a month ago, the lume is incredible, you know you are wearing a fantastic dive watch when its on your wrist. Its a watch that you have to see and hold to undestand how special it is.

[@mr.ethings1545]

Welcome to the club! Its really crazy how bright and crisp it is even when I wake up in the middle of the night! Hands down the best lume of any watch I have handled. The only weak lume on the watch is the numbers (...10...20) on the bezel but it doesnt bother me that much. Love the huge Inverted triangle pip and the 12'o'clock! Truly a function over form watch while still being beautiful!

Awesome review. I'm a SLA021J1 owner as well. I have some wounds on my watch that the diashield was unable to protect. It takes a beating. My watch runs about 6 seconds fast per day. I leave it crown up to settle at a flat 0. Its very impressive on the timegrapher. On par with my swiss watches. Hopefully in a few more years I'll send it off for a servicing.

[@mr.ethings1545]

So awesome, I dont have many wounds on the case, but the ones that I do have I definitely don't mind. Those are MY marks on the watch. The difference between owning a watch and collection one. Mine unfortunately runs 4 seconds slow now so I will be sending mine into service soon!

[@mr.ethings1545]

Just checked the stock bracelet on my MM300. Only the links with the arrow marks are removable. That being said, I have similar sized wrists to you and I still have 2 more removable links so the MM300 will fit you just fine!

[@skduncan1974]

I've often wondered why nobody makes the white frame around the date to actually be lume. That would give it some better symmetry in darkness. I have several swiss brand watches that i truly love but i just always circle back to Seiko and specifically this model. I think this will be my next big boy watch. Great review btw.

[@mr.ethings1545]

I saw they have a new model of the MarineMaster in which they squeezed in a lume marker next to the date window a the 3'o'clock but I noticed that they didn't actually redesign the date to move over to make space so instead the lumed marker is eating into the chapter ring which makes the face look even more off balance so in the end I don't feel the need to "update" to the newer model. I agree with you, there is just something about this model that hits all the right notes! It truly is a "if you know you know" kind of watch.

[@skduncan1974]

@mr.ethings1545 I agree. My SPB185 has that lume marker at the 3 that is pushed to the far edge of the dial. Looks weird but I do love the watch!

Was there any issues when you removed the “non arrow mark” link at 6oclock? I need to remove mine but it’s a link that’s isn’t marked with an arrow. I need mine to be the same as yours. Thanks

[@mr.ethings1545]

I dont think you can remove the non-arrow mark links. Do you mean the one that connects to the clasp? But that one also has an arrow mark on in. Coming from the end links on the watch: At the 6'o'clock I have a two non arrow links and then a single (half link) link with an arrow that connects to the clasp From the 12'o'clock I have 3 non arrow links and then 2 regular arrow links and then the one half link that connects to the other end of the clasp I hope this helps clear it up!

[@rajnaran]

@ yes. So on your 6 side you had to have removed a link without an arrow to achieve this. Unless it was done before your ownership. This is because originally there are actually 3 non arrow links after the end link followed by the half link that connects to the clasp. Do you recall any problems from that 3rd no arrow link that you no longer have on your bracelet? Sorry and Thanks again!

[@mr.ethings1545]

@@rajnaran I am the original owner but i dont remember ever removing the non arrow links. The arrow and non arrow links look identical but the difference is that the arrow links do NOT have a taper to them where the non arrow link (coming from the end links) are tapering.

but it looks like the 3rd link without the arrow (furthest from the endlink) doesnt taper, so if I were to remove one of the non arrow links, i would do that one first

I see your also a little bit of a mechanical keyboard enthusiast as well! In regards to a fully indexed bezel, its almost a must for me. why should the accuracy of me readings suddenly drop off at the 15/20 min mark? i can forgive it in cheaper/beater watches though

[@mr.ethings1545]

Agreed! I would say that according to Navy dive tables, used to determine bottom time before dive computers, on your first dive you max bottom time at 30 meters would be no more than 20 minutes, so I guess they only felt like they only needed the first 20 min. That is just me trying to justify why they did it that way but IMHO i prefer a fully indexed bezel! And also ya mechanical keyboards are cool hahah

Although the newest version has a lumed marker at the 3 they no longer put the classic white border around the date window. Also if you look carefully the Lumed marker at the 3 actually is eating into the chapter ring leading the whole thing to look a little unbalanced and not as classically handsome as the previous models.

It is pricy, I bought a Padi Edition Turtle and then Modded it, then a solar tuna, then a citizen, before finally just biting the bullet for the MM300. It is still the most expensive watch I have ever bought. If I could do it over again, I would have not bothered with the cheaper watches and just saved for the one that I wanted, the MM300. As I still wear the MM300 all the other watches collect dust. So in the end I ended up spending more money! If youre looking for value and quality, I go between my Marathon MSAR and the Marine Master300. The marathon is cheaper but still awesome!

the lowest i went in water was my bathtub :D. i dunno, my heart tells me to buy the MM, but my brain tells to go maximum Longines Hydro Ceramic. - i also love the Prospex LX but that is even way higher price. i love Seiko 'cause they make tOOl watches, not fancy watches like the Seamaster. i admit, it is a great watch, the Bond watch, but i wanna be the one who differs ...

@@ji1787 oh between all those choice, the MM300 is the easy choice. I dont like the hands on the Conquests.

The Propex LX is an impressive bit of engineering but personally I like the subtle tick of a mechanical watch. Also the size of the LX and its crown through the whole watch off. If you were to go for the LX i would rather you wend with one of the Grand Seiko Divers. In the end the MM300 is an amazing watch especiallyy when you pair it with a strapcode bracellet.

[@mr.ethings1545]

I am very biased as I have already spent the money on the watch and love it but I cannot deny that you have a point! Recently had a friend ask me about watch suggestions and pushed him in the direction of Omega over the MM300. His priority was on value retention and prestige over functionality (which is a totally valid reason especially since he isn't a diver)

[@manuel_winde]

It’s worth considering that Seiko can usually be picked up with a discount- which is less possible with omega and Tudor. I got 33% off a nearly new mm300/sla023 which makes it cheaper than a Doxa or Sinn. Whilst they’re both nice watches the Seiko is more special to me and also more versatile. The only watch in the similar price range I would pick over the mm300 is a Tudor bb58… but my wife knows how much tudors cost so it’s easier for me to get an mm300 and pretend it cost £500/$450 😄😄
