Tudor Pelagos VS Seiko Marinemaster 300 Comparison: Which Is The Ultimate Tool Dive Watch?

[@MERKAMGCLK]

I just traded a Doxa for an SBDX001. My Marine Master has ruined me for most of the other watches in my collection. I can not take mine off my wrist.

[@BrettinLux]

I own both of these watches and they are totally different watches.My MM300 is my work watch as part of my job is diving.My Pelagos is my weekend or dress up watch. One thing is that the Pelagos hurts my wrist if I wear it for a full day.The crown at 4oclock on the MM helps so much and that’s not an issue. Both are keepers that have a permanent home.

[@davecypress]

Great vid and comparison, captured the pros and cons really well, bit harsh on the 8L35 movement which is an in-house, master crafted tank. Value retention contest goes to the Seiko here. Overall different pieces, despite the 500m label Pelagos in titanium is a luxe item worn and traded by watch enthusiasts and celebs like Beckham; mm300 with monocoque steel case is the essential tool watch for divers and weekend warriors alike.

[@Albdentist]

I agree 100% the Seiko is a real life every day diving watch..it can take the abuse..the first thing I noticed was the weight, heft of the thing..built for punishment of the sea..

[@KRW628]

I must respectfully disagree. These are both super watches; but they aren't in the same league. The Pelagos lists for $17-hundred more. And it shows. If the Tudor was a 3-thousand dollar watch, it wouldn't be a contest. That being said, I'd have the MM300. I'm a Seikopath.

[@Zeus-kj7nn]

Pelagos feels like a cheap toy watch in the hand, the looks stade. The Seiko has heft and more character. Its a saturation diver with much more intent. A watch that will never get boring

[@johnt1115]

No comparison in my opinion. The MM300 has “wow” factor the Pelagos will never have. Amazing character, fit, and build. The deep balanced dial is outstanding. Wearing it on rubber is juvenile. Leather, fabric, and NATO with the MM is awesome. Extremely versatile watch. The Tudor is truly boring and bland in person. This scoring is nonsense.

[@resjon7981]

After seeing my friends Pelagos drop from 3ft onto concrete and stop winding and had to go back to Tudor for repair, I conclude these watches are not tool watches. The SNE569P1 is your only tool diver. Good video anyhow.

[@HarryFlashmanVC]

I work in oil and gas, you see MM300s on the wrists of our Saturation Divers, I never, ever see a Rolex/Tudor/Omega etc.

[@ericb8888]

💯 the Tudor is for Topside Dive Supervisor and Ops Managers. Tudor is never seen SUBSEA ;)

[@efreutel]

Hands down Seiko, with that incomparable monocoque case and hand assembled movement.👍👍👍

[@johnleonard3951]

Only thing i dont like about the Pelagos is that it looks like there is a poem wrote on the dial.

[@drbobsnightmare2521]

If it was a beauty contest the MM on an Angus J Louie wins hands down.

[@craigwoolbert2443]

love love love my Pelly! Agree with all your points. Yes the contrast of the black and white is amazing and with my 53 year old eyes it's fantastic.

[@johnhealey6455]

Great video! Seiko for me. It’s a much more beautiful and interesting watch, and that lume is so good. Nothing else quite like it.

[@davidstjohn7943]

Love the vid; you always put together such an insightful package. The best tool diver from Seiko, for me, is going to be a Tuna. That Pelagos is a machine. I can't get on with it looks-wise (the Marine Master kills it) but something about the uncompromising toolness of the Pelagos is just totally impressive.

[@thewatchidiot]

Thank you so much David that means a lot to me! Glad you enjoyed the video! Yeah the Tuna is a formidable tool watch no doubt and I had one for about 1.5 years before selling it and I really miss it (especially the insane lume). Yeah in terms of looks I cant get enough of the MM300 but i think getting a SPB185 might be the best way to experience most of the curves and finishing of the MM300 while getting extra usability. However, the SPB185 is an option only because I've fully experienced the MM300. The pelagos is always there ready to do whatever is needed of it and i dont think the intense contrast between the hands/indices and the dial will ever get old!

[@alexxela3933]

Agreed on the poor bracelet of the mm, however let's not forget to mention that there's many options available with great bracelets from strap code tailored to the mm, and it's fairly priced... I think it's worth mentioning about those aftermarket options 👍🏻 Had the pelagos and it felt dull, flipped it after few months... I still have 2 mm 300 as keepers, the sbdx012 and the sla023, to me the best divers on the market and yet reasonably priced. Great review nonetheless bud 🍻

[@startrek889]

I have SLA021 and I bought SLA047 for my son. 😊

[@HarryFlashmanVC]

I disagree, I find the OEM bracelet on the MM300 is fine and does a good job supporting the watch. I INITUALLY sisnt like it, however, over time I appreciate it. I think the issue is that people are so used to hearing how bad it is, it becomes expected. IMHO the issue is that due to the size of the links you have to ensure that the clasp is properly located on the wrist for the OEM bracelet to sit properly. The clasp is long so the 6 o clock side needs to be one pink shorter than the 12 o clock side to position the clasp on the curve of the wrist and to avoid kicking. Every time I have seen a 'bracelet crap' review, the bracelet is never ever properly fitted to the wrist in this way. Set it up properly and its absolutely fine e and comfortable. Furthermore, I have never, ever, had a problem with activation the wetsuit extension by accident, on my watch it is actually quite tricky to extend it.

[@MrBacchus18]

I'm thinking of adding a blue Marinemaster to pair with my black Seamaster. Maybe I am being influenced by the popular picks but I have loved the Pelagos for quite a while.

[@thewatchidiot]

that would be an awesome duo for sure! I havent seen the blue dial variant in person but I can only imagine that Seiko did an awesome job. If you havent seen the Pelagos in person I would definitely recommend doing so bc feeling the silkiness of the bracelet is so awesome paired with how (relatively) light it is!

[@manuel_winde]

I just got the blue mm300 and it’s an incredible dial. The layout of the dial and overall look of the watch is one of the best I’ve owned, it genuinely makes me smile. I’ve always loved the blue pelagos but for me (and my 7in wrist) it just wears a bit big/awkward in comparison. The mm300 and bb58 both wear really well but the mm300 has a lot more heft which I like as I’m a bigger guy. The case shape curves nicely on the Seiko. I don’t hate the mm300 bracelet like many do but I do also wear it on a variety of rubber straps and natos and it looks great on all of them. The pelagos comes with bracelet and rubber too and looks great on both but I don’t see the pelagos looking as good on a leather strap or even a nato… in fact the pelagos on any rubber strap may not even worn but the Seiko works great on pretty much any rubber strap. Both clasps are great but the quality of the pelagos clasp/bracelet is better as you’d expect at that price difference. (I got a new mm300 for 35% off easily enough but there’s little to no discount on a pelagos.) Accuracy/movement as you say - both are great movements but there’s no “luck of the draw” with the tudor regarding accuracy. The Seiko movement is cool and fine but Tudor is just better.

[@paultowns9880]

@@manuel_winde . I also have the blue mm300 , you have summed it up perfectly. Videos dont seem to do the dial justice. Wear in good health.

[@stevebennett7783]

I love my MM300 and it muscled out my BB58. It's such a unique watch and different from the other Swiss entries but it's horses for courses and I've never owned a peligos so I don't really have a comparison. However against my no date sub it certainly holds it own. Other than the bracelet haha

[@thewatchidiot]

The look and the overall experience of the MM300 is what made me fall in love with it and is what keeps me excited. I know I'll miss it when I sell it but it doesnt make sense to own it just for the sake of owning it and the joy i get while wearing it every once in a while. loool yeah the bracelet is awful and actually i really do think that i would have kept it if it had a bracelet that was made to the same standards as the watch itself. Fingers crossed it gets updated!

[@mikejackson3869]

Thanks for a great video. I had a sbdx001 which I sold a few years ago and I kind of miss it. I sold it, as like you say it wasn't getting enough wristime. I also have the Pelagos lhd, Omega PO 2500 in 42mm (my fav), 168000 transitional Sub as well as a few vintage Seiko 6105 and 6306-7000's. I was thinking about buying another MM300, especially I love the gold seconds hand but I am a Prospex X hater! Your review is accurate about the MM300 drawbacks and you may have saved me the money from buying a "nostalgic" purchase. I might just save a little longer and try a titanium GS spring drive diver or the Omega NTTD.

[@anthonystevens8683]

A very well put together video TWI, I've never worn a Marinemaster but I do have the Pelagos. Like you mine is the most comfortable watch that I own. That's probably because it's made from titanium and the fit with that bracelet is perfect. It is a big watch though but is also one of the best to read the time at a glance. Mine is the LHD version that has a slight cream colour to the hands and markers (also has that roulette wheel date ring) so I'd guess that the one you have would be a bit better to read at a glance. One other thing I love about the Pelagos is that the hand stack and dial fit very close to that sapphire crystal. I certainly do not wish to sell mine.

[@thewatchidiot]

Thanks as always Anthony! yeah the Pelagos is definitely a comfortable watch "like a comfortable pair of shoes" like you put it earlier! The LHD version has always interested me and i feel like if it was 40mm then I would be really tempted to get one without stepping on the toes of my pelagos. fingers crossed for 2022 lol! Yessssss I forgot to mention that in the video but yeah the tight tolerances of the dial on the pelagos is really cool kind of in the same way that the intense depth of the dial and crystal on the MM300 is really cool. If I had to sell all my watches except one, my Pelagos would be the last one standing!

[@anthonystevens8683]

@@thewatchidiot I love the standard Pelagos that you have, I wouldn't get another version as those toes should not be trodden on in those comfy pair of shoes LOL. One of the other reasons I went for the LHD at the AD was that they are all numbered and the one that was shown to me ended in 633, "633 Squadron" was one of my parents favourite black and white movies from the middle of the last century so that was the final decision on the purchase.

[@thewatchidiot]

Lol it's best to keep all the toes away from steps! Oh wow that's so cool that the LHD happened to have a number that was so special to you! Definitely a very good read to get it and honestly if I had seen one with a special number when I was buying my Pelagos I probably would have bought the LHD as well. Can't pass up opportunities like that!!

[@robertsullivan4773]

Love my blue Pelagos. Have no experience with the Seiko so I won't comment but will say accuracy is pretty important to me. One thing I noticed is you didn't mention the Pelagos comes with a rubber strap. It's not great but it is more.than serviceable and it has an extension piece so you can wear the watch over a wet suite. Last comment I have no idea why people have a problem with the titanium it sure doesn't wear to light and has a very nice warmth to it on the wrist I have a small wrist and the Pelagos disappears on my wrist five minutes after putting it on.

[@thewatchidiot]

Yeah accuracy is important to me so thankfully I was able to communicate with Gnomon Watches before buying my MM300 and I asked them to send me one that is accurate and they sent me a pic of the watch on a timegrapher which was very nice of them! Honestly I completely forgot about the Pelagos rubber strap! Thats pretty much down to it being extremely uncomfortable on my particular wrist. since its quite stiff and the top ends are thick, it pinchs the top of my wrist too much and t was unwearable. I really wish it was better bc it would have been a really cool look! But yeah I'm with you, I absolutely all things titanium, the experience and comfort are unlike anything else and as for the Pelagos it has heft but it makes the watch just light enough to make it disappear!

I was watching this while wearing my Pelagos - it's been on the factory rubber strap for ages which I do love style-wise but at some point soon I'll likely go back to the excellent bracelet. There's no diver I'd rather have!

[@thewatchidiot]

Got my Pelagos on too! As much as i love the idea and concept of the factory rubber strap, the top end of the strap is just to thick and stiff for my wrist so it ends up being super uncomfortable unfortunately. I feel like I'm missing out on the other side of the Pelagos experience! Yeah you should definitely try the bracelet again!

[@nightstalker824]

Great comparison! These 2 watches are on my radar, as well the Omega seamaster 300. This is what I'm thinking, as dumb as it sounds, but I've been researching for months. This is a big purchase for me. I'm leaning towards the Tudor. As much as I love the Seiko, it still is a Seiko. The Omega looks like a dad watch, especially the bracelet(yes, I'm a dad), and the Tudor just looks modern and badass at the same time. Thanks for the review!

[@sheed1]

[@mylovelycameraman]

Here because I was contemplating on purchasing the MM300 and Ai Tool suggested an alternative, hence the Pelagos. . . And I’m still unsure which to purchase. 😢

[@Koishishibaman]

Great review on two very nice tool watches. I don't have a Pelagos so I can't really comment on it. I do have a couple of mm300. One on a bright orange dassari rubber strap. Attitude for this one. This one is my grail diver. The other is on the OEM bracelet. I got a great fit on it. Like it on this watch. The bracelet balances out the heavy watch head. The Seiko has a gorgeous case, the pelagos looks for like a tool. Very different looks.

[@jorad4887]

Seiko's has more accuracy than any Swiss watches and many Swiss watch companies take expired old and out dated patents from Seiko and move that old technology into their watches while Seiko is on their 200+ patents leaving them all behind, I'm staying with the Seiko marine master spring drive, the most accurate watch the most over engineered watch ever built.

[@clark3830]

I agree,use the rubber strap for the Seiko and get a different metal bracelet for it with shorter links if you do not like it. Simple fix. The AD would be happy to sell it that way.

[@maximepapazian4122]

Love your presentation thank you

[@markbyrum4743]

Good vid. Don't know why Tudor doesn't make this clasp sized for the Black Bay 58. Good vid. Keep at it!

[@degenerateWA]

Huge fan of both brands. I think Seiko watches look much better (by that I mean they are more fun) and Tudor watches feel much better. As we all know one being better does not mean that the other is bad.

[@mainlymusicman]

i had both these watches. i sold the pelagos and kept the marine master. pelagos just gets boring after a while.

[@donaldneo4317]

I am 1 of those guys that could not get the bracelet to fit as the clasp does not center on my wrist and so I have been wearing it on the factory rubber strap. The plus point is that it makes it even lighter. 1 question, does your Pelagos have the same endlink rattles like your BB58?

[@NICKVST]

Where would you recommend picking up a marine master 300?

Does your Tudor clasp pull away and catch on stuff ever? Feels like it happens often. Those corners are really sharp too!

These are the most thorough and thoughtful comparisons out there. Going through the categories rather than just doing stream of consciousness is so good. Thanks A kinda random question.

[@RagnarHoff]

I want that Marinemaster so bad, but i hate that it doesn't have a caseback because when it performs -30 sec a day and I want my watchmaker to regulate it, they basically have to send it in to Seiko to be opened through the front. I don't see what the advantages are.

[@ggrandcz]

Then change your watchmaker, because it is so simple to open MM.

[@nicks8026]

Great comparison. The Pelagos is one of my favorite watches but I never wear it on bracelet, although the bracelet is excellent. It’s my activity watch - sailing, climbing, backpacking, etc. - so it’s always on rubber. I’ve beaten the hell out of mine. It still looks great and runs at 1.5 spd on wrist. A really amazing bit of kit. As for the Seiko’s bracelet, its subpar nature is no surprise, really. Seiko just don’t do bracelets well. Part of the reason I sold my SPB185 was the craptacular bracelet. Even the bracelet on my SBGE255 is just okay (maybe good) when it should be great.

[@Patomelb]

It actually surprises me that GS don’t make amazing bracelets

[@frosty4peter]

That Pelagos is one of the best diver watches on the planet. Maybe right after the Seadweller 4000 which is the best imo. I just found one ;) but I also had the Pelagos and sometimes I miss it because it wears like a dream! Not to big and not to small. And the bracelet is also one of the best! That having said : The MM300 is also a georgeous watch (the SLA047) Only that bracelet is to fat for me. On the rubber strap it wears I think. And about the movement : It is one of the best and keeps time for many years once you regulate it. Believe me there is NOTHING wrong with that GS movement in it!

[@NWind-go9qn]

So, 500m depth rating is just a gimmick. Saturation diving at that depth is so rare that anyone of the handful of humans that have been there in the last 50 years are not the likely customer base for a Tudor Pelagos. If those guys were not wearing a Rolex at those depths, it was likely because they didn’t bring it on the job and brought a knocker instead. I wonder how well the titanium bracelet and case would withstand the rigorous professional diving environment in terms of scratches and so on. The coating on a MM can look brand new even after some pretty tough thorough goings.

[@gasken2182]

No one has mentioned the dreaded R word. Sister company to Rolex or not, makes it hard for me to buy a Tudor. I’d always wish it was a R submariner. But because the cynical restriction of supply Rolex does, has pumped the prices of both brands, so now I don’t want either. It’s much like the way De Beers restrictions the prices of diamonds to artificially keep the prices high. I can’t abide by this cynical kind of price pumping.

[@lengx.9798]

I have to say that Sinn makes some best tool divers.

[@thewatchidiot]

Yeah Sinn no doubt makes some incredible stuff I used to own a U1! As much as I loved its super brutal tool watch look and feel, it just didnt get enough wrist time bc for me it just wasnt versatile due to the look + the size. I wish I could have kept it but i felt a bit guilty having that much locked away in a watch that didnt get the wrist time it deserved. The U50 might be a winner tho😁

Two great watches that I’ve wanted for a while. I previously owned and sold a sbdx017 but caved in and got a sla023 (blue version) and I love it. The pelagos was in my thoughts but for me despite the weight difference it just wears a bit bigger on my 7in wrist. Despite the measurements and weight the mm300 wears really well for me- maybe as I’m quite big (fat😄) and I like the solid feeling of heft. Anyway great video and whilst I didn’t agree on every part (be a bit weird if I did!) it certainly made me reconsider the pelagos but for now I’ll enjoy the Seiko, which was about half the price of the pelagos. And maybe in a year or two I’ll come back to the pelagos. If both watches were a millimetre thinner/smaller here and there they’d both be perfect. But I do feel that the Seiko perfectly imperfect as all its flaws are part of its character (something Seiko manage to get away with that most other brands can’t. It’s a sort of X factor/tool watch thing that allows owners to laugh about faults that would be a big deal with any other brand!).

@@Fcyhcfyc yeah the lug to lug is longer and it doesn’t curve at all. The mm300 looks and wears smaller as well as curving to fit the wrist better in my experience. I had the same issue with the Speedmaster which was ok but due to the long lug to lug and no curve wore bigger than I’d have liked.

Total nonsense.. I've yet to hear from anyone who has a marine master that is out more than COSC. The Seiko case is polished the same way as Grand Seiko. The Tudor is just brushed. The Seiko is so hermetically sealed it does not need a helium escape valve. It is known to be waterproof wayyyy past the stated depth. To knock seiko for the modesty on the depth rating and accuracy is childish . You are a fan boi. The Tudor is a horrible straight slab with a hole in the side plugged. The finish is basic.

[@lonewolfemcquade8133]

Great comparison 👏 dam I would love a Tudor Submariner no date with Mercedes hands and a real riveted bracelet or a bracelet without rivets maybe even make a new bracelet & clasp all together Tudor clasps are definitely not the best. I doubt a Submariner would happen though because it would probably upset the Black bay line a little to much unfortunately

[@defender1006]

Thank you for a very interesting comparison on two great watches, however they are two quite different watches and as such comparisons can be very much objectified, such as when comparing the movements, you didn't really draw any significance about the date complication, which can be a make or brake point for some people? Again the on the wrist experience can be very different from one watch and wrist to another? Personally I think the MM300 is far closer to a Tudor 'Black Bay' as it's down to the size and how it wears, the rest of the dynamics are purely personal choice!

[@NWind-go9qn]

You’d probably would ‘t want to pressure test your pelagos to 500m. But you know your MM would have no problem at 500m. Seiko under-rates their own watches. Not that Sat divers get too many chances to go that deep anyway.

Tough call there but, in all honesty, i have to hand it to the Pelagos - it's just a superior watch and in titanium.

One of the best diver ever vs an Happy Meal toy.

The Marinemaster changed my watch life. The Pelagos could never do that. Bruce Williams didn't buy five or so different Marinemasters for nothing. It's the best, despite Seiko making mistakes by removing the "Marinemaster" wording and sticking an "X" on the dial. Sacrilege.

[@8AP1]

MM300 has a non replaceable crown tube. For this reason alone the Pelagos is a better watch

[@panosvrionis8548]

Tudor looks stamped....🤔 Seiko looks machined 🤗 like someone spend time in lathe

[@rhonda837]

some people have had the lume fall out of the bezel on the pelagos.

[@realestwatchreviews]

Heimdallr makes a titanium MM300. Just putting that out there…

[@stevebennett7783]

Unfortunately it's not a MM300. Looks like one but that's where the similarities end.

[@thewatchidiot]

@Hammad and Fatima nice I didn't know about that, looks like someone has the right idea lol!

[@Aztec1050]

The Tudor is better. Seiko has 2 weaknesses: 1. The crown tube is integrated to the case if it gets worn (eventually) the watch will be disposable 2. The magic lever auto wind system wears out in the long run

[@fire_watch7735]

As always great video. I also own both and I’d hate to have to choose between them because they’re both amazing and very different from each other as well as other watches. I have an 8.5” so none of the large size issues are a factor for me. Cheers

[@thewatchidiot]

Thank you so much, happy to hear you enjoyed the video! Yeah its impossible to choose between the two of them the only reason the MM300 is going is because it just doesnt get enough wrist now which is unfortunate. Maybe it will come back as a rebuy lol!

[@lynnlittle8671]

I owned a Marinemaster 300 several years ago, I currently own a SBBN031 Tuna Can (on basically the same bracelet as is on the Marinemaster 300). The Marinemaster 300 is a very nice watch, but, IMO, the Pelagos is a better every day hard use divers watch. The SBBN031 Tuna Can for me is much preferable to the Marinemaster 300. I know, apples to oranges... Anyway, I hope to find a blue Pelagos on my wrist someday soon, if I can get my black BB58 off my wrist.

[@ryanrabe7184]

Why pelagos looks big compare to a MM300????

[@hybridstrength5065]

The dial presents bigger than the seiko. Makes it visually larger although the seiko has a larger case.

[@Judah.Rosenthal]

Bracelet is the reason I don’t own a MM. The watch looks great but if it’s not comfortable, who cares? And in a strap it has zero appeal to me.

[@jh-il5sb]

you are correct with your mm300 bracelet accessment....it really is terrible. I had to change it out, but the watch is amazing

[@thewatchidiot]

Yeah the bracelet is unfortunate but does that mean that every watch you own is on a bracelet? if thats the case then you're missing out on the glories of the strap world and in this case the insanely cool MM300 watch head! I love wearing bracelets but some watches sing on straps😁

[@Judah.Rosenthal]

@@thewatchidiot So e watches look great on a strap. 103, Speedmaster and obviously a lot of more classically sized and styled. But, to me, a MM300 on a bracelet is the only way to go. Now.. wonder if one of US’s would fit… 🤔

[@clark3830]

Tudor is a poor mans Rolex. Seiko is a value built watch. One is just ego and the other is actually value made for a watch. People need to get back to the days of the 40's to 50's when you bought anything for its actual use value and not ego/designer crap. Think of when tee shirts where just tee shirts for a buck or so. Now you pay high prices for advertisers! Why? Stop buying this Crap for egos and manufacturers benefits and things will return to real values again. PS: I bought Rolex and Omega when they were cheaper 20 years ago and giving them to my son to sell when I pass. I love the Seikos and the mods.

[@pedromanuellopez142]

Dear WI, you are getting braver and braver. Even if Seiko were to finish their Marinemaster to the level of the Pelagos, there is no way it would match up. It looks crude at every level. And that against the Pelagos which is not exactly svelte or graceful by any measure.

[@stevebennett7783]

I'm assuming you've never owned a MM300 then? I have a no date sub and the watch (not bracelet 😬) holds up very well against it. It's a far prettier watch than the very sterile Pelagos but as I stated, it's horses for courses. I've used mine on dives and it live on a rubber strap.

[@thewatchidiot]

Yeah I'm not so sure that you have seen one in person bc the Pelagos is finished nicely for sure but it really cant be compared to the finishing of the MM300 considering that it the watch gets built at a Grand Seiko facility. I have owned 3 Grand Seikos/still own 2 and the finishing of the MM300 still amazes me when I see it. If you dont like the design of the MM300 then thats more than ok bc its definitely not a watch for everyone but the quality of the finishing is undeniably good for a watch like that!

[@pedromanuellopez142]

@@thewatchidiot well, ok, I am just not so in favor of polished finishes on tool watches. I am wondering where I could go see one, but I cannot think of a well stocked AD in Vienna.

[@thewatchidiot]

Oh I'm the same way, for me I want my watches to have as many brushed surfaces as possible! But the MM300 is an exception for sure. Also the nice thing is that when it's on the wrist the polished areas aren't really visible and only the brushed tops of the lugs are visible. Yeah definitely try to go see one in person unfortunately I don't know any ADs in Vienna lol! Fingers crossed one of them has an MM300!

[@jdc3636]

I have the MM300, I’d rank the Tudor over the seiko here.

[@merc7paul]

The answer is both😂

[@damnbrosky]

I do not care about this few seconds of accuracy if all this watches are not perfect, mehanical watches are not accurate at all and you cant set it as points, if something is 1 second or 10 sec wrong it changes nothing coz you know that every 5 dollar auartz will eat your rolex on brekfast, accuracy means nothing for me but rest yes

[@dimatha7]

Casio Duro all the way

[@weeleung6043]

The problem with Shitko?You pay £2000+ for MM,once on the wrist, it could be a £250 Shitko, there's no WOW factor. Omega, Rolex, Tudor etc? Once it's on the wrist ,Once you knows the model and then you definitely know the value.

[@HarryFlashmanVC]

Are you compensating for something? You need the 'security' of a 'brand'? Well, each to their own I suppose

[@WildManActual]

The correct answer is Sinn U50, lol

[@mainlymusicman]

the accuracy of my marine master was just as good as my pelagos. id put the movements equal

[@Patomelb]

I own Rolex so When I see Tudor watches I’m like meh 🫤 but not in a snob way but I don’t get excited by them. But then i see the higher end seikos like the MM300,LX range and all their SLA models that are made by grand seiko and I’m really impressed! 3k to 7k watches that have hand finishing hand assembled movements, ect. Brands like Tudor are fully made by machines. Seiko is such a strange company because these SLA/LX models are as good quality as Rolex but then anything below MM300 is trash and cheap. I tried a king turtle J model and it looked like a toy compared to my Marinemaster so I sold it almost immediately. I can see how seiko blurs the line with their watches which leads to most people thinking they are trash watches.

[@markbyrum4743]

Good vid. Don't know why Tudor doesn't make this clasp sized for the Black Bay 58. Good vid. Keep at it!
