Review: The Tudor Black Bay Chrono Replica With Steel Case For Men

Luxury Fake Tudor Black Bay Chronograph, $4,900+

We know, we know — this is far from the first black bezel copy Tudor Black Bay Chrono you’ve come across on the pages of Gear Patrol, or elsewhere: there were black ones, special ones, steel and gold ones, etc. We get it. But this one is different.

This one resurrects the “panda” dial and the “reverse-panda” dial, classic, mid-century configurations that represent the pinnacle of chronograph aesthetics. Also — this version is thinner than past versions, which is welcome news for those of you with slimmer wrists, or who simply prefer the look and feel of vintage models. Let’s dive right in.
Key Specs:

Case Diameter: 41mm
Case Depth: 14.4mm
Water Resistance: 200m
Movement: Tudor Cal. MT5813 (COSC)
Price: $4,900+
The two new models — panda (white with black sub-registers) and reverse-panda (black with white sub-registers) — are each available in three configurations: on bracelet, on a “Bund”-style leather strap, and on a fabric strap. This gives the user a choice of two different price points as well as different band options. The case size has also been slimmed down somewhat to 14.4mm, which, while still chunky, is thinner that that of previous iterations. In short, this is a handsome, classically inspired take on the midcentury chronograph that should provide a great alternative to sister brand Rolex’s Daytona. It also stands well on its own.
If you want a Daytona but you can’t find one, or you can’t afford one, or you don’t wanna be yet another dude wearing a Daytona, then this is the watch for you. If you dig midcentury chronograph aesthetics — especially the whole “panda” dial thing — then this Tudor copy watch with steel bracelet is for you. If you just like chunkier, hefty tool watches, then this watch is for you. If you like to time things, like pasta boiling on the stove or how long you can stand on your head, then this watch is for you. In short: this is a watch for many, many different types of people.
Well, you could go for a Daytona. (LOL.) If you can get your hands on one of those in steel at retail, it’ll set you back $13,150. Despite a price difference of over 2x, there are still a fair number of similarities: sizing, dial configurations, in-house movements, etc. Though of course the Daytona uses a triple-register layout and leaves out the date.

Zenith’s Chronomaster Sport is a page out of the old Daytona book, and thus a good alternative to the BB Chrono — though it’ll run you $10,000 on a bracelet. Moving a bit downmarket but sticking with the dual-register-plus-date configuration, we’ve got the Intra-Matic Auto Chrono from Hamilton for $2,195, though it comes on a leather strap. The layout and similarities in look are striking, however. Another good reverse-pandal option is Yema’s Speedgraf, an awesome, affordable mechanical chrono with a dual-register layout and an uncommon movement from Seiko. They’re about $1,500.
We’re talking about a 41mm fake Tudor Black Bay chronograph with a 14.4mm depth and, on my review model, a matching steel bracelet. So first things first: this thing has some heft to it. And that’s welcome, frankly — a svelte, dressy Patek 1463 or 1518 this most certainly ain’t, but you also don’t have to worry about banging it around.

Our favourite rumours ahead of the launch of the uk cheap fake Tudor Marine Nationale

Tudor replica had an incredibly strong showing at Watches & Wonders this year, with the collecting community almost unanimously praising their releases. While the models introduced were not necessarily brand new, they definitely put the novel in novelty. The Black Bay Fifty-Eight divers explored new materials by using precious metals for the first time.

Tudor shocked us all by not only dropping a rather expensive configuration in yellow gold, but a more price-approachable 925 silver model as well. The cheap replica Tudor Black Bay Chronographs had both their cases and dials refined, conveying evidence the brand listens to their fans thinning the watch and making it that much more of a solid Daytona alternative. But the fun isn’t ending just yet as, shortly after the fair, Tudor announced a revitalised partnership with the French Navy Marine Nationale. The two entities have a longstanding history together, with some of the most coveted Tudor copy watches being Marine Nationale issued Snowflake Submariner divers. The announcement has, of course, led to rampant speculation within the watch community, so we wanted to share our thoughts on what may be coming very soon. Here are four Tudor Marine Nationale rumours we have seen shared online that we’ll rate in terms of being “most out there”, “most unlikely”, “most likely”, and what we think would be “most appropriate”.
Tudor Marine Nationale Black Bay Fifty-Eight Replica With Steel Bracelet

Tudor fans have been begging for a more compact take on the successful black dial replica Tudor Black Bay GMT that presented buyers with a more accessible and affordable take on a Wilsdorf Pepsi bezel watch. While I do not think the idea is out of the question down the line, I don’t think the complication has a strong tie in with the Marine Nationale partnership. I also think it would be a very bold move for Tudor to withhold such a hot novelty from Watches & Wonders.

French Navy Revives Iconic Partnership With Cheap UK Fake Tudor Online

Revisiting some of its early roots, Swiss luxury watchmaker fake Tudor has now announced a new partnership with the French Navy (aka Marine Nationale), rekindling a relationship that goes back more than half a century.

Many Tudor and watch enthusiasts will know that the brand’s relationship dates back all the way to 1956, just several years after it released its first luxury Tudor dive replica watch. Over the course of the next three decades, the two will collaborate on a vast number of projects, which included the iconic references 7924 and 9401.

While details regarding the specifics of their new partnership remain scarce at this point, you can expect it to involve some form of dive watch and military dive teams, perhaps from the cheap replica Tudor Black Bay or Pelagos lineups. Tudor says that there’ll be more updates and announcements in the near future, so fans of the brand should definitely stay tuned for more news to come.

The New UK Swiss Luxury Replica Tudor Black Bay Chrono Panda Watches

The Black Bay is, without doubt, the most successful collection of cheap fake Tudor. This watch has been instrumental in the resurrection of the brand in the early 2010s. Since its introduction in 2012, this vintage-inspired diver’s watch has been a commercial hit and the collection has been enlarged with multiple complications, in various materials and in a wide range of colours. The collection is a classic for Tudor, mixing modern execution and retro-looking elements, such as the iconic Snowflake hands or signature applied indexes. And in 2017, the brand introduced its first Black Bay Chrono, which caused quite some reactions… A good base for sure, but there was room for improvement. Well, it’s here, with the new editions of the high quality copy Tudor Black Bay Chrono for 2021. And we have a video review of these models too, that you can check on top of the article.

The Black Bay is like a piece of well-oiled machinery for Tudor. One edition after another, its road is paved with success. And even though the recipe is well-known and the evolutions are most of the time quite conservative – not always, as seen with the 925 Silver edition – it remains the brand’s best-selling collection, by far. But, from time to time, one of the version can cause some discussions.
In 2017, Tudor launched a chronograph based on the Black Bay. Not the first chronograph of the brand, which already has in collection racing-inspired models such as the Heritage Chrono, based on the Montecarlo. So, in order to differentiate this new black dial copy Tudor Black Bay Chrono from the rest of the crowd, Tudor gave it the Black Bay touch with some diving credentials – both in terms of design and specifications. Also, and importantly, this watch marked the beginning of an industrial alliance between Tudor and Breitling, as the movement found in the Black Bay Chrono was (and still is) openly presented as based on a B01 architecture. Nothing wrong with this. Actually, it is something we even applauded back then.

The issue was somewhere else. What caused discussions was the strange mix between diving elements of the Black Bay – the dial, its indexes and the Snowflake hands – and racing features such as the chronograph (even though diving chronographs are far from new) and the tachymeter scale on the bezel. The Snowflake hand, and the way it could obstruct the 45-minute counter even cause strong reactions… More on that later.
All in all, the first generation of stainless steel case replica Tudor Black Bay Chrono had some strong arguments, was a solid base but still was perfectible on some aspects – some of which were totally subjective. A couple of years later, the brand launched a black-coated version, the Dark Limited Edition. Finally, there was also in 2019 a two-tone version of this chronograph, which was somehow announcing the evolution that has been introduced this year, with a black bezel and contrasting sub-counters.

Do we have to keep going? Fine, we will: here’s more of us waxing poetic on the charms of the BB58, and a few reasons why we think it’s the right watch for you — whoever you are

It’s The Perfect Size
Rolex upped its Submariner to 41mm last year. Whyyyyy. They had such a good thing going. Anyway, the steel bracelet Tudor replica watch is 39mm. 39mm is just like 40mm, but one better. (“It’s one more loud.”) Seriously, though, this is the Goldilocks size for dive copy watches. Throw one on and you’ll agree. I haven’t met a single person who’s tried one on who disagrees. Now if we only get them to make a damned 39mm GMT…
It’s Got All The Fixins
In-house movement, chronometer certified. Matching rivet-style bracelet. Awesome-looking snowflake hands and highly legible design. 200m of water resistance. 70 hours of power reserve. Awesome aluminum bezel insert. Oh, and it also tells the time.

It’s Beautiful
I mean, just look at that gorgeous gilt dial. And if that isn’t enough to get your heart racing, then what about that new blue version? The high quality replica Tudor just gets it. Their design team understand proportion, nuance and restraint, and the result is a watch that only an evil step-parent could hate. (I think I got that metaphor backwards, but you get it. The watch is sexy.)

Line of Succession: Reviewing the UK Cheap Fake Tudor Heritage Black Bay Chronograph

The best quality fake Tudor Heritage Black Bay Chronograph profits from a collaboration with Breitling while drawing deeply from Tudor’s own history. In this feature from the WatchTime archives, with original photos by OK-Photography, we give the watch an in-depth review.
Our photographer appreciates high-quality products that have a story to tell – like his Leica camera that’s been around since 1954, attached to a leather strap from Cyprus that has a unique, well-worn patina. As he’s staging the copy Tudor Heritage Black Bay Chrono for our photo shoot for this review, it occurs to him that he prefers classic objects with no “sell-by date.”

Tudor draws characteristic elements of this watch from models in its past. The curved sapphire crystal and dial recall the first Tudor dive watch. The oversize “Big Crown” is a design feature of the Reference 7924 from 1958, the first Tudor replica wristwatch to be water-resistant to a depth of 200 meters. The water resistance is printed in red on the dial of this watch, just as it was on historical models. And the new model’s “snowflake” hands are like those on the Tudor wristwatches that were supplied to the French Navy in the 1970s. History also connects the new fake Tudor Heritage Black Bay Chrono Ref. 79350 with the world of motorsports – represented here by the chronograph with its fixed tachymeter bezel, which has been a feature of all Tudor stopwatches. Tudor introduced its first chronograph, the “Prince Oysterdate,” equipped with an ETA/Valjoux 7734 movement, in 1970.
This new model’s movement is the result of a collaboration with Breitling. The two brands are now sharing expertise in the design and production of mechanical movements with the aim of developing more in-house capabilities. Using Breitling Caliber B01 as a base, Tudor has installed an in-house regulator with a silicon hairspring – a joint patent of Rolex, Patek Philippe and the Swatch Group – and then placed its own rotor on top. Tudor calls it the MT5813 caliber and it has been certified by the COSC as a chronometer. (In turn, Breitling is using Tudor’s MT5612 caliber as a base movement.)

Tudor clone has made another technical modification to the original base movement. Like its first chronograph, the subdial at 3 o’clock has a 45-minute range instead of the usual 30 minutes.
The Big Crown sits inside a long tube. After releasing the screw by turning it counterclockwise, the crown jumps out for the purpose of manual winding. It can also be easily pulled into the correct positions for quick-date adjustment and hand setting, and then returned securely to its screw-down, locked position.

The date mechanism is designed for quick and easy date correction. When the watch is running, it advances to the next day precisely at midnight. It makes a strong impression in black and white at 6 o’clock. The resulting omission of a luminous dot here and at 3 and 9 o’clock is no problem, since the remaining eight glowing dots and the triangle at 12 o’clock, along with the substantial hands, make it easy to read the time day or night. The chronograph function of Tudor copy with stainless steel case retreats modestly to the background during the day and disappears at night.

UK High-quality Tudor Black Bay Dark Replica Watch For Sale Online

But this is all black?! Let’s be honest, the perfect fake Tudor Black Bay 58 with its goldilocks 39mm size is probably the best example of the red triangle inspiration, an amalgamation of MIL-spec Submariner and a classic vintage Tudor.

39MM Replica Tudor Black Bay Dark Watch

But we all know what the 58 looks like, so here’s the broody darkness of the 1:1 best replica Black Bay to sex things up. In all its menacing blackness, this is a damn cool 41mm Rolex family case, and what a way to emphasise that red triangle.

Waterproof Fake Tudor Black Bay Dark Watch

Don’t get me wrong, I love the original look of pure brushed steel, but this makes those two red details Pop (yes, with a capital “P”). The case finish is as exquisite as expected, the DLC is among the hardiest on the market, so this is a damn tough tool and a nice way to stand out from the 58 crowd.

UK AAA Quality Replica Tudor Black Bay 41MM Models Still Sell Well In Stores

While I may argue with said individuals, plenty of forum posters and Instagram commenters claim that 39mm is too small for them – and only caters to puny wrists. Personally I find this complete blasphemy, but for the sake of word count I will not get into this rant now – and ultimately if it is not my money or wrist then it’s not my decision.

Stainless Steel Fake Tudor Black Bay Watch

Sure the perfect fake Black Bay Fifty-Eight watches are highly sought after, with likely waiting periods before purchase, and respectable resale values over retail pricing secondhand. But I think we can all agree that we still see Black Bay 41mm watches in the wild. The larger Black Bay models have more variants to choose from when you think about it. Yes, the dials are mostly black (with a few exceptions), but there are more bezel configurations than the two available in the BB58 line and the BB58 has yet to be fashioned in bronze (currently only used in larger 43mm Black Bay Bronze watches) or PVD-treated steel. Also, don’t forget, the in-demand Harrods Black Bay 41mm is the closet Wilsdorf-produced alternative to an aluminium Kermit in the marketplace today.

Black Dial Fake Tudor Black Bay Watch

Another example of Swiss made replica Tudor and 41mm being a success is their wildly best replica Black Bay GMT watch, that is as equally scarce (if not more so) than the BB58 in store. With a lug to lug of 50mm, the issue with 41mm models in the catalogue has arguably never been about case diameter or even lug to lug – but we’ll get into this more in a second.

Deep Black: Testing the UK Fake Tudor Black Bay Dark For Sale Online

A black replica watch is perfect for diving in deep dark waters, and it looks great on dry land, too. In this feature from the WatchTime archives, we test Tudor’s popular model in its recently launched all-black version: the Heritage Black Bay Dark.

Over the past several years the black bezel fake Tudor Heritage Black Bay has grown into an important and attractive watch collection. It was launched in 2012 with a retro-look model in stainless steel with a red dive-watch bezel, followed in 2014 by a more reserved version with a blue rotating bezel, and then one year later with the simplest version so far, in black.

Tudor set off a new round of reworks in 2016 with the introduction of the Heritage Black Bay in bronze, in a 36-mm case, and with an ultra-sporty completely black version. Plus all new and existing Heritage Black Bay models will use the in-house MT5602 movement instead of the ETA 2824, which was previously used. (The MT5602 was introduced in 2015.)
A wide range of different straps and bracelets continues to add variety. Each watch comes with either a three-row stainless-steel bracelet or an antiqued leather strap, and a fabric strap is always included with either option. The boldest choice is the 36-mm 2016 Tudor model with an “urban camouflage” fabric strap.

The watch we tested has a black, brushed PVD-coated stainless-steel bracelet that matches the case. While the dial has a matte finish, the rotating bezel stands apart with a shiny aluminum track. The fact that the ring is not made of ceramic, and is therefore susceptible to scratches, is rather difficult to overlook in a watch that costs more than $4,000.

The 41 mm copy Tudor Black Bay Dark’s sturdy and functional in-house movement has minimal decoration.
But an entirely positive feature is the movement, especially in light of copy Tudor’s traditional values of precision and sturdiness. This little brother to Rolex meets initial expectations by ensuring the inspection of every movement by COSC, the official Swiss testing institute for chronometers. In addition to other criteria, COSC certification requires that the watch’s average rate deviation remain within -4 and +6 seconds per day.

Our test on the electronic timing machine confirms this precision. However, in contrast to the official test, we also tested the sixth position, crown right, which revealed a minor outlier in the minus range. While this position is rare during everyday use – it occurs only when raising the wrist to read the time – it is essential for people who store their self-winding watches on watch winders because many of these machines might leave timepieces in a vertical position during rest periods that can last several hours.
Various technical properties of the “Movement Tudor” MT5602 fulfill the second part of the brand’s philosophy: sturdiness. First of all, the robust nature of the 6.5-mm-high movement ensures that no functional problems will occur due to minor tolerance variations. Secondly, the balance is not supported just on one side by a cock but instead lies completely straight and secure beneath a bridge. And thirdly, the silicon hairspring ensures that no deviation in rate will occur in the event of a disturbance or impact resulting from centering errors or deformation.

Additional quality features of the manufacture movement include the long, 70-hour power reserve and the variable inertia balance with four regulating screws. The rate is no longer regulated by changing the active length of the balance spring, as was the case when the Heritage Black Bay had an ETA movement. Even though Swiss movement fake Tudor used a different fine regulator in the ETA 2824, a stable variable inertia was possible only with the switch to its in-house movement.

The watch’s link bracelet ends in a functional folding clasp and safety lock.
The brand has invested very little effort or cost in decorating the movement, which is consistent with the philosophy of providing reliable watch technologies at a reasonable price. Mechanical watch enthusiasts who may be driven to open the fully threaded caseback (with the correct tool, of course) will discover minimal decorations, limited to a skeletonized and brush-finished rotor engraved with the Tudor name.

Tudor has omitted a date display for the Heritage Black Bay Dark, which we see as a positive change. This sports-design watch follows in the tradition of the Tudor Oyster Submariner of 1954, which also had no date display; its clean, unadorned dial simply has eight round and three rectangular hour markers and one triangular marker at 12 o’clock. The striking hour and seconds hands with their distinctive “snowflake” shapes can be traced to the second Submariner generation, which was presented by Tudor in 1969. The watch’s water resistance today is 200 meters, as it was in 1958. This was an impressively high value at the time of diving pioneers and remains sufficient for most recreational divers today.

In this way, the cheap fake Tudor Heritage Black Bay Dark unites the best of various classic models – now in the casual black outfit of a very trendy sports watch. It’s the coolest way to dive – not to mention the best way to bring diving history into the beach bar.

REVIEW: Cheap Tudor Black Bay Fifty-Eight Navy Blue Fake Watch UK

In 1958 Tudor introduced their first divers’ watch, water-resistant to 200 meters/660 feet. It was reference 7924 also known as the “Big Crown”. This is where the modern Black Bay Fifty-Eight (BB58) derives its name.
The Black Bay Fifty-Eight line as a whole pays homage to the brand’s first divers’ watches. However, in 1969, Tudor introduced a divers’ watch with a blue dial and bezel. Other sports watches in their collection soon followed suit, immediately creating a lasting aesthetic hallmark known as “Tudor Blue”. Adopted by the French Navy during the 1970s, the Black Bay Fifty-Eight “Navy Blue” follows in this tradition with its navy blue dial and aluminum bezel insert.
Already seeing much success with the original fake Black Bay Fifty-Eight in 2018 — largely due to its faithfulness to vintage Tudor and Rolex Submariners — the latest blue version is poised to sell similarly well considering it builds on existing BB58 demand and ties in the historically significant Marine Nationale shade of blue.

Stainless Steel Fake Tudor Black Bay Fifty-Eight Navy Blue Watch

This is the watch in for review, the perfect replica Tudor Black Bay Fifty-Eight Navy Blue Ref. 79030B-0003 with a manufacture caliber MT5402. The caliber MT5402 is certified as a chronometer by the Swiss Official Chronometer Testing Institute (COSC) and is a 4Hz automatic movement with a bidirectional rotor system (that winds in both directions), and has a power reserve of approximately 70 hours. The movement has a thickness of only 4.99 mm, the main reason for how slender the watch is.
The screw-down winding crown displays the Tudor rose and like its predecessor is water-resistant to the same 200 m/660 ft. The bezel is steel and is rotatable unidirectionally with a 60-minute graduated insert in matte blue anodized aluminum with silver gilded markings and numerals. A domed sapphire crystal protects the dial. Applied hour markers and Tudor’s signature “Snowflake” hands complete the neo-vintage aesthetic. As was its 1950’s counterpart, the modern model offers a stainless steel case 39 mm in diameter — keeping the characteristic proportions of its predecessor (more on that later).
The BB58B was shipped for review paired with Tudor’s blue and white striped fabric strap. Interestingly, the strap looks like a Nato style strap but is actually engineered to have spring bars pass through it so it sits as a quasi single pass strap. This allows it to have a Nato look but a standard buckle and tail finish, having no extra length of strap to fold over as you would find on a traditional Nato-style watch strap. The material has a tactile feel and in this configuration, the watch weighed in at 76 grams and with a retail price of $3,375 as shown.

Fake Tudor Black Bay Fifty-Eight Navy Blue Watch For Men

I decided to give the navy blue BB58 a true test of wearability and authenticity to a watch whose DNA it’s emulating: my 1992 Tudor Submariner Ref. 79090. As a side note and a topic for a whole other article, I refer to watches over 25 years old as “vintage.” For insurance and registration purposes, the age of a classic car in most cases must be at least 20 years and when I polled the Instagram #watchfam a few years back, 25-30 years old to be considered vintage was the overwhelming consensus, so, therefore, I’m considering the 79090 as “vintage.”
Dimensions between the modern Black Bay 58 Ref. 79030B and the vintage Submariner Ref. 79090 are strikingly exact. In fact, the only measurable differences lie in that the vintage submariner has crown guards where the BB58 does not and in case thickness. Before all the purists and anti reissue collectors groan over these subtle differences, they are both misleading. In measuring the case diameter of the vintage Tudor minus the crown guards and crown you’ll find it’s the exact same 39 mm as the BB58.
The other difference, as mentioned, is in case thickness. If you’re a watch nerd like me (and if you’re reading this, there’s a pretty good chance) one would naturally think this means the modern BB58 is going to be the thicker of the two. However, we must dissect further. The 79090 without the crystal measures 10 mm versus the BB58 at 11 mm. Deceiving once again because the thicker top hat acrylic crystal of the vintage sub makes the thickness dimension the same 13 mm as the modern BB58 with its 1 mm thinner sapphire crystal. All other measurements are precisely in line with each other. Both have a lug to lug distance of 47 mm, a 39 mm case diameter without crown, and the same 43 mm with the crown. They also both use the watch collectors sigh of relief, 20 mm lug width.
