I've just seen the Sinn u50 in my watchforum for the first time and absolutely felt in love with it. It's a very unique design language 👌

Just purchased the Sinn U50 limited edition " mother of pearl" which is a toned down version of the original. Also have the bb58 and there really is no wrong choice here as all of the watches are excellent!

If I separated myself to how impressed I was the first time I looked at each of the 3. The Sinn gave me the "I need that" feeling more than the other two that are more of a "I want that" feeling.

I owned the BB58 and U50 at the same time. The BB58 was absolutely amazing. Comfortable, versatile, handsome and the perfect size for my 7” wrist…but I rarely wore it due to fears of damaging it. In recognition of that I purchased the U50. After having the U50 for almost 3 months, I sold the BB58 to the AD I purchased it from. I do not have the same level of worry about the U50 because it’s so resistant to damage. Btw he was really pleased I approached him first. I miss the perfection that the BB58 was on my wrist but don’t miss the guilt of not wearing it. And I love the more rugged look of the U50. And how ridiculously comfortable it is as well. Wears like a 40mm. It also looks good with a sport jacket.

I vote for the U50 between this bunch.

"Try to tune out the outside noise." The way Bruce does with comments about his hair. 😂

As an owner of the BB58 I think it’s worth every penny. This was my first Tudor watch I ever owned and was really impressed with the overall quality. In my personal opinion I think it is the most versatile out of these three options. The BB58 is truly a “strap monster.” I’ve worn it with suits and also on nato straps. It’s a fantastic piece.

I have the Seiko and I’ve owned the Sinn. It’s the Seiko for me and it’s not even close. I have an 8.5 inch wrist and can wear it everyday. Finishing is better than both IMO. Also has tool free micro adjustment in the clasp. No brainer

I have a Sinn U1 blue as my daily wear and I work with my hands in pretty rough conditions. The watch still looks almost brand new. Go with the Sinn, it’s the best value tool watch. Emphasis on tool watch.

I have a Sinn U50 S (the all black version). I wear it on a genuine Isofrane strap. It is the most comfortable watch I can remember wearing in the larger watch era (last 15-20 years). Having said that I have a casual primarily office job, so I can wear a diver 24/7/365. The least I have worn it in 7 months is 1/2 a day. It is pretty much 24/7 including sleep and shower. It looks like it just came out of the box. Not a mark on it. Previously, I wore a Sea-Dweller pretty much 24/7 for about 6 years. Not nearly as comfortable and did take dings and scratches. The Dweller is a great watch though- don’t get me wrong. I love the U50. It is very unique and I have yet to see another one. 7 months and still on the honeymoon it is so thin and comfy.

I have the SLA021 and GS SBGA375, the MM300 got the most wrist time !! Such as great watch

I agree with Bruce's points but my takeaway would be this: If you are moving to a one watch collection or if your diver watch is your everyday watch, then go for the bb58. If you have a different beautiful everyday watch and a diver watch is a tool watch you want in your collection then get the mm300 or u50

Wearing my MM300 today

Seiko MM300 is my choice by a fairly wide margin. It’s rugged and beautiful at the same time. The lume is incredible. Now that the new models have sapphire glass and ceramic bezels the Seiko definitely gets my vote.

That MM300 looks amazing, really impressed by it, although as Bruce mentioned top heavy and could be a chore to wear as an everyday watch. I have the BB58 Blue Which I've had for a year now and can say it wears amazing, so comfortable and just looks well refined. I'm not a big fan of the Sinn but I do like the bracelet design of it. Good luck, I don't think you'll be disappointed by any of the three.

I had the same debate with myself a few months back. BB58 or Sinn U50 SDR-T. In the end I went for the Sinn because of the larger case size (I have a wrist of 7.5in) and the tegimented case. I love the fact that I know basically nothing will scratch my watch and therefore I wear it to whatever. Another pro is the bezel. It's a 60-click bezel which feels incredible. Cons of the Sinn: the clasp. It's outdated and not nice to use. Hope they update it someday.

The Black Bay is pretty much everywhere, and the Seiko, as awesome as it is, has no access to the movement for regulation purposes. It does, however, have one of the best clasps I've ever used (IMO). As for the Sinn, I think it hits all the right notes at a great price. Definitely my pick.

I have the Sinn and the Tudor. Ideally if you could swing it try to get both. I’m not a Seiko guy. But of the two I would take the Tudor All day long.

I own the Sinn and absolutely love it. Although it is definitely a tool watch, it looks and feels like a very premium tool, nothing dull about it. It’s different and cool, the people who own Sinn are mostly enthusiasts.

Sinn is very utilitarian - not very versatile. Seiko is nice, but for my wrist is too big, if you can pull it off, than it's a good watch to consider. BB is the most versatile and elegant watch among those 3 in my eyes. I would suggest to consider Sinn 104 or something from EZM collection. Another watch to consider is Longines Legend Diver, but unfortunately it lacks a good bracelet

This has been a question I've been asking myself for months. I'm a serious sinn fan and have a couple already so that attracts me there. The Tudor has the dressy aspects all covered and is slightly different to anything else I have... in the end i bought a previous gen seamaster to avoid the conflict. Now the conflict is raising its head again!

Bruce, this was a really informative video. It's great to get perspectives like yours, especially since you're clearly a true enthusiast and appreciate all brands, and have had hands on experience with tons of watches. Would love to see more videos of this format! Thanks!

Go with the BB58, it’s a safe and great daily watch. The MM300 is one of those watch that you must love to own, not for everyone.

"If you are into retro design, the Tudor is up your alley". Seriously? Seiko MM is up that alley too. The design of Seiko MM has not altered much since the original inception and has a longer history compared to Tudor BB which was launched in 2012. The only issue that may be a factor is the thickness.. but hey, it is a professional tool watch designed for professional diver.

Lance should consider the Breitling Super Ocean Heritage. All of the three mentioned lack wrist presence to a degree. The Sinn is a quirky piece but somewhat appealing when in the mood for industrial, but more like a $1500 watch.

I’ve been crushing on the mm300 for a couple years now

if he wants a watch that can be used in dressier situations, the BB58 is the only choice. I own a MM300 and love it, but even though it wears small for it's size, it's a thick watch

This is for lance , get the blackbay 58 you will like the in house 70 hour power reserve, the size is perfect for a 7 inch wrist , and it's an everyday piece that you can wear with a suit or at the beach with t shirt and shorts , plus it has more to offer than the Seiko or the Sinn it has the value retention, you will be able to get out of it with little or no loss of capital ..ask me how I know ...you will buy and sell the others and end up with the Tudor.. buy it and be happy ...

Great thoughts on the 3, I have a mm300 and love it, but for everyday wear the tudor is probably a better choice comfort and wearability wise.

If the MM300 is for you, then you would have bought it already. As far as I'm concerned it's the best watch ever (yes I'm biased) but it isn't for everyone. One thing for sure, if you buy the BB 58 and then see the mm300 in the wild, you will go into a state of depression with strong feelings of inadequacy.

Pelagos is amazing - I prefer the LHD

Sinn is cool different and more interesting. Possibly my favourite watch brand.

I got a VC 4500 black, a Speedmaster FOIS and just got my U50T. The Sinn is the most comfortable to wear and it attracts no attention at all which is exactly what I want for an everyday watch. You can just put it on and forget about it. The lego hands and AR coating make it so easy to read the time and data. Also the T steel Sinn uses has a "warm" feeling(feels a bit like rubber) on the wrist comparing to my other two SS watches, which makes it even more comfortable for long period wearing.

This video couldn't have come at a better time, im trying to weight up a BB58 vs a U50 SDR-T and this has certainly helped!

I just got the U50 and can confirm it’s probably the MOST legible watch I’ve ever seen. The legibility is what makes it beautiful. It looks so good on a nato and really pops with a red rubber strap. The other two here are boring in comparison.

I really love the Sinn out of the three and that would be my first choice, hands down. You really don’t see a Sinn out in the wild very often and it would be a great conversation piece for watch geeks. . Next would be the Seiko, although agree its bulky. With a 7 inch wrist the Tudor may be a bit small and its a hype watch. Good luck Lance with the hunt!!

Second comment on the video. Bruce, I liked that you picked a watch and didn’t just double talk the whole time. Too many KZfaqrs are afraid to give a specific recommendation and that’s annoying. People want to know an opinion or your idea of a clear winner and they can agree or disagree but it’s much more satisfying than hearing someone talking around the issue and giving a trophy to everyone.

Having “juggled” with these same choices (except for MM 1000 w/ GS mvmt), I landed with the Sinn U50 SDR. I couldn’t be happier. While I liked the Seiko I was after, it would have been too big for my 6” wrist and I felt the BB58 was honestly too dressy for my Tool choices. In the end, get what you want the most.

Was on holiday in Jamaica 3 weeks ago and was able to pick up a BB58 from an AD at the airport for just under $3K. Probably could have gone lower if my flight wasn't taking off. Point is, you can still get discounts on the BB58 new.

I’m a HUGE Sinn fan owning both a 556A and 857 UTC TESTAF, but I also own two BB58s - the blue and 925. While I don’t have experience with the MM300, I would personally advocate for the Tudor of the 3 choices here. The fit, movement, versatility, and, like it or not, Tudor name carry this watch the farthest of the three, in my opinion. All great watches, but Tudor is the way to go, just don’t pay over retail for it.

MM300 hands down. The finest quality built of the 3. Superior in every way to the other 2. The Sinn U50 is too small. The U1 is better balanced. Plus it's the original of the 2. The Tudor is just yawn. It is a lot of hype.

There is what is the best watch, and what is the best diver. And there is also what a person is looking for in a watch. I think the BB58 is virtually un-debatably the best watch of the three but the MM300 is without question the best diver and the most mesmerizing (a commercial diver would care about the first part). In the end what is a person looking for in a watch matters most. If you need a profesional tool to back-up your adventures or your livelihood, you might chose the MM. If you are more of a pure watch enthusiast you might get the BB. If you are a sportsman you might chose the Sinn. And so it goes, of tastes and colors volumes can be written.

1:36 Ahahaha the Steinhart vs. MK argument meme was hilarious! Greatness! :D

Definitely the BB58 would be my choice it is a wonderful watch and has the best chance of increasing in value over the years

Man, tough decision. I feel that the U50 is the cooler or more eclectic of the options. But I think the BB has more recognition and hype surrounding it and it can be dressed up in ways the Seiko or the Sinn cannot be. I don't think any would be a bad choice for the money spent, but I would go for the Tudor! 😎🍻👍

For a do it all watch, go with the BB58. All three of these are awesome watches, but the Sinn and the Seiko will have slightly narrower parameters of wear. Bruce makes great points. Good luck!

I think you need 2 out of the 3! Sinn for abuse…I have the sinn ezm3 diver which I fish/mountain bike/general abuse with and you can use either the seiko or bb58 as more daily wear..I love the seiko but do find myself enjoying thinner watches more and more..I wear the new seamaster 300 for lighter duty..all great choices though! Good luck

I'm a planet ocean owner, but I still really fancy a seiko mm300 for some reason.

I think the best overall out of the 3 is the Marine Master because it has a Grand Seiko movement! Sinn is good but not sure about Selita movement.

I agree with Bruce. I own the Tudor and wear it daily. It really is a very special watch. Very well finished - no flaws, not even under a loupe. Incredible movement - mine has been perfectly accurate for the last two months,. The gilt dial is stunning and it is very comfortable to wear. There is a reason there is so much hype over the BB58 - it deserves the praise.

Great and thoughtful video but for 3K I’d rather have a Breitling than any of those 3. 🤭

Love them all but BB58 all the way baby!

I've owned the Tudor BB blue and the U50.... and the U1. Sold them all once I had the MM300 on my 7 1/4" wrist. There is something about the Tudor snowflake hour hand that I just couldn't get used to. The U50 was incredibly nice and well balanced but again, something about the hands just wasn't doing it for me. The MM300 really is the perfect watch for me. It's just there. It doesn't scream anything but comfort and quality and I like that.

i'll go Tudor bb58 every day.

Good advice Bruce and a very good overall review of all three watch’s. I would also recommend your viewer to consider the SPB185J. Thinner and with the safe fit and finish as the MM300.

I’ve owned the Sinn U50-T SDR and the BB 58 Black-the Sinn is a far more special watch. It feels like the better build quality, fits the wrist better (I have a 7”, and the BB58 is a touch small) and is a unique design while the BB58 tends to feel like any number of homages I could have bought for less.

In that price range, Omega would top my list (even if it means going to preowned).

i vote for mm300 i love mine!

I had the same conundrum... Tudor or Sinn? I'm glad that I bought both. The Tegemented Sinn is tougher than the Tudor, and is really comfortable on the wrist. It's my beach watch. But the Tudor has a better movement and looks good. Sinn offers first class after sales service through It's UK service agent, and for me that was a factor. The Sinn is DIN 8306 compliant so it's totally trustworthy. Mine has chronometer level accuracy, as does the Tudor of course. This Seiko is too tall for me. Thank you for the video, really enjoyable. 😀

The Seiko MM300 is the best looking dive watch period, if Seiko can slim it down a few mm.

Great comparison vid!! I couldn’t decide 😭 so I got a Pelagos, a couple lower end Seiko divers, and I just sold my U1 SE to purchase the U50 S. As I progressed through my “habit” I really appreciate the thinner case! Like Bruce said, in the end the only thing that matters is your opinion and which one you like the best they’re all fantastic time pieces!! Either way congratulations on your new acquisition and enjoy the hell of it!

I'd pick the Sinn personally, the others don't really do anything for me.

Tough choices, I’d still go with the Seiko or even another color Sinn. Not sure why, and don’t blast me for it but Tuud is kinda boring and stiff……yeah I know, you could say that about the Sinn but for some reason the Tudor is kinda stuffy. I appreciate all the tech and innovation, call it subtle however I feel like the other two are fun in their own way……like asking a German to translate a funny joke in English to German…..always comes out rigid without soul but funny and with character, especially if you’re have a drink.😂 The MM is unique, solid case, a bit tall but Jesus, what a purposeful watch that also looks great at a concert or wine party! Seiko, Sinn in another color for me…..certainly not the Tudor. Not much happens with the Tudor besides adding numbers at your tax consultant.

Out of these 3 : the MM300 all day! No question at all. I had several divers . The best is the Seadweller 4000 . Followed by the real Pelagos and the MM300.

I’m not sure where you live but I just went into my Tudor AD and they had plenty of Black Bays. Also, if you don’t intend to dive with it or even get it really wet get the Tudor. For myself, I’m looking for a new dive watch and my options currently are the Sinn U2, U1, U50 (in this order) and the Damasko DSub50. With a 7 inch wrist all of these will work. I’ve tried on the Black Bay 58 and thought it was a little small on my wrist (also 7 inches). If you really want a Tudor, get the Pelagos 500 meter. By the way, I’m a diver and have been for many years so I know dive watches.

Agreed, all nice watches, but the black bay 58 has a special place in the collection - it's one of the best all-rounders - colours that work so well together, size, details, fit & finish - on the money. A keeper.

The Tudor is by far the most versatile, and it's got everything: heritage, quality, performance, and a classic look. The others are more extreme in looks, and may exceed in other aspects and not in others. For an everyday mostly one watch collection, I'd get the Tudor. And I'm Seiko fanboy. For my collection and soul, I'd take the Seiko any day.

Since seiko is in the mix, you can get a few different grand seikos from their sport collection for under $4k, from a 100m to 200m water resistance. That Explorer 2 looking one is included in that, though only a 100m, another all steel with blue bezel at 200 m.

Hiya.The Sinn looks the buisiness to me .I am very practical though and wear a watch to tell the time easily and dont use a watch as a man jewell.Just looks serious as a timekeeper.Thanks.

Totally agree. I have the exact BB58 Navy. Comes across at AD just walking in. Then fell in love with the Tudor and buy the Tudor GMT as well.

Love all three but the sinn would be my choice as I am a hardcore tool watch enthusiast. That teg sub steel is definitely my jam

Get the black bay. Will be ideal for your wrist size and the price will likely go up in Jan 2022. I just got mine, didnt struggle at all in the UK to buy one at retail, just walked in and bought one.

Appreciate your analysis, Bruce. I’ve been drawn to the Sinn too, but have been concerned about visual fatigue after a few months. Useful to hear your experience with it.

As a tool watch MM300 ticks all marks excellent build quality with zaratsu polish and grand seiko derived movement little chunky but I also have 7 inch and lug to lug is manageable and it beats sinn which has selitta generic movement, next choice is the BB58 but it’s more dressy in my opinion and little bland.

I would go for the seiko mm300 💪 Sinn doesn’t fit my taste, BB58 Is really handsome but a lot of people already have BB58.

I'd go for the bb58 or the Sinn. The mm300 is just too big and bulky for my liking..

I have the Sinn U50-T fully Tegimented version and a Tudor Black Bay Steel 41 mm. Both excellent watches. My Tudor isn’t the Black Bay 58 but the build quality and materials are basically identical. The Tudor is definitely a better quality and finished watch as it should be for the money. The bracelet is 10 times better and so is the bezel with its precision and I love that it has a stop at 12 o’clock. The Sinn really shines in its case construction and materials technology and is crazy thin for 500m water resistance. The bead blasted grey and funky handset limit it somewhat to casual/sport use. The Sinn bracelet is cheap and the clasp the level found on $100 watches. It’s a great watch and I love how durable it is but the Tudor is the better watch from a quality and build perspective. The Sinn at less money is a solid value and a great no-fuss daily. Neither watch is going to age well from a style perspective and are not “classics” even though the Black Bay is closer to that but the faux patina won’t date well I don’t think. That’s why I went with the Black Bay Steel because it’s a bit more classic even though I sacrificed thickness and diameter.

Thanks for another most informative video, Bruce. These are all great watches. The Sinn U50 is the one I pine for. Just looking at that beautiful blue BB58 on your arm, I can’t help but notice that the bracelet is already scuffed in places. Easy to rectify, but a pain to keep doing. The Sinn has no such problems… truly an everyday tool watch, but possibly cumbersome over the long run, as you pointed out.

All three are great choices, I have two weeks with my Sinn U50 full T version and it has the updated Sellita SW300-2 movement with a longer PR of 56-60 hours. I love the Sinn because it's a Pro-Diver and tool watch which looks good on rubber or even a textile synthetic strap.I sold three Tudors and 7 Seiko Divers so the Sinn U50 T is staying. I will compare it to my Oris 65 Chronos limited edition ice blue dial which arrives today from Holstein CH and see. One Diver/Sport/Tool in Sinn and the Oris as a "Chill" piece.

Kind of a subjective question. They're all nice peices and all have their plus and minus points. Personally, I like the Tudor.

After 1 year, my BB58 blue still stuns me. Excellently done watch.

Sinn fan here but I gotta say, agree with the BB58 recommendation. The U50 can tire after a while unless there's lots of other options in the collection. The BB58 is pure class and lot more versatile.

My vote goes for the Sinn. I have the Sinn U200.

One consideration that is alluded to but not explored, is the likely depreciation of the three watches. If the prospective buyer is one who likes to trade up then the likelihood is that the Tudor will be the one to buy. Ultimately, I buy what I like the look of on my wrist and don't flip them but appreciate that's not always the case

Bruce, keep up the great vids, awesome channel. I'm trying to decide whether to go for the 2021 Tag Aquaracer or Oris Aquis Cal400. What do you think Bruce?

Having previously owned the Seiko mm300 and Tudor bb58 and then come close to getting the Sinn and a Doxa recently… I got another mm300. Price wise you can get the Seiko and Sinn for around the same price and I think quality wise they are all pretty similar. Tudor is the best “one watch”, daily wearer and the most versatile of the 3. For a normal human being it’s the sensible and obvious option. The Sinn is a great tool watch and is a bit different but ultimately would be in third place for me. It’s a bit too different and modern for me. The Seiko is perfectly imperfect and it looks and wears much better in real life than on paper. For me it works well along with my Reverso and completes a great 2 watch collection. It’s different enough that it’s a conversation piece at meet ups or whatever but it’s not weird or odd.

I have the Tudor which has been my daily wear for a few years now, just got the U50. The U50 is a better deal and tech, Tudor has the provenance and a tad more dressy looking and should hold better value. Can't go wrong with either there. No experience with the Seiko, but I will get a Grand Seiko some day.

U50 all the way, even though I'm a Seiko fan I find their divers hard to wear on a daily basis. Love the aesthetics but if it doesn't wear well it will just sit on the nightstand for ages.

Great advice. One and done - go with Tudor BB. If you already have a dressy watch in the collection, go with either of the other two.

Bruce is right, that Sinn is brutal. From the bezel to the crown, a brute. There is no delicacy to turning either. If a Viking were to go berserk and start loping off heads, he would wear that Sinn. But.... he'd be doing it in style. It just looks damn good.

I sold my Sinn U1 to get the U50 but opted for the BB58 Gilt. Right decision for me, first watch I can honestly say would be my one watch collection. Would still like a U50.

I definitely agree with a lot of your thoughts here. I tried the MM300 (green) on at the AD the other day. Although lug-to-lug I certainly was fine with my 7.25" wrist, it was a bit tall/top heavy. I don't feel that way with watches like the Turtle, Willard, or new 62MAS. I feel like I would be knocking it against every other door knob I encountered. It was beautiful, just not for me. I've only tried the BB58 blue and the silver BB58 on straps, but they wore quite nicely. I think it would be well balance size and presence-wise on my wrist with the bracelet. The feel of the Tudors is top notch. I respect the Sinn U50, and think it's cool, but I liked that word brutal. I think I'd find it neat to wear something very modern for a short time, but might tire of it later. I don't think I would tire of the BB58, as it is a well rounded watch. For what it's worth, a buddy of mine recently picked the black one up his first stop into an AD near a major city. They sold him one on the fabric strap, but ordered the bracelet for him at a big discount and it showed up within 2 weeks. He's really pleased with the watch. Pro tip: Order the Uncle Seiko half-link for the bracelet for a better fit.

Hope that Lance has the iconic SKX007 on jubilee in his collection. Don't worry about the minor imperfections as it should satisfy the Seiko Diver urge for decades on. Plus a cool watch with it's own swagger. Tudor logo/snowflake is a turn off, daily reminder of not scoring a Rolex. Better off putting the 5k to Rolex or Omega fund.

I like the MM300, love the Sinn but the Bland Bay's I really dislike..so for me it'd be the Sinn, because I like it's individual brutalstyle,but do get what you say about " tool fatigue" . MM300 too chunky & pricey ( I'd want a more prestigious name for the price). I'd go for an Omega 😉 Good video, look forward to hearing which Lance chooses. Good luck mate . Thanks Bruce 👍👍

Sinn for the win

I know he doesn't want to get involved in the hype but all 3 are firm forum favourites 🤣🤣🥰🥰

I'd go for the Sinn. The MM is great, but the downside of zaratsu polishing is it's going to be scratched up easily. Fit and finish on Tudor is far behind either of the others.

I have the sinn and Tudor. Both are so comfortable, so tie there. For me, the bb58 is more flexible as stated, but next to the sinn, seems like a fashion watch. I agree with others, if you are going for one, go for the bb58. If you have a dress watch or everyday watch I love the sinn, it’s so fun and is def more rare and intriguing. Also, I think watchbuys says my u50t has 56 hrs.

The only advice I would add is to try to get each of these watches on wrist and then decide.

Absolutely Sinn
