As we explained when Tudor introduced its latest vision of a vintage-inspired dive watch, the?Black Bay Fifty-Eight 39mm, internal competition is getting stronger than ever… BB41mm or BB58? Tough choice! To shed some light on the situation, we have staged a face-off between the Black Bay 41mm and the?Black Bay Fifty-Eight 39mm and arm?you with all the details to help you choose between what are, obviously, two great watches.Background – the Black Bay conceptThe Tudor Black Bay was?born in 2012, as the second step in Tudor’s revival era – one year after the Heritage Chrono and the same year as the Pelagos – under the Philippe Peverelli/Davide Cerrato management tandem. The Black Bay clearly redefined the brand, repositioned the collection, made the brand sexy again and put it back on the road to success. The Black Bay was – and still is – the brand’s best seller and will remain the milestone of Tudor’s recent history.The three versions (black, blue, burgundy) of the Tudor Black Bay 41mm Ref. 79230.The first model was unveiled at Baselworld 2012?with a burgundy bezel. The Black Bay was positioned as a modern-sized but historically-inspired dive watch, with contemporary specifications and vintage design elements. The inspiration can be seen in various 1960s watches, such as the?vintage Submariner Ref. 7922, Ref. 7923 and Ref. 7924. With a diameter of 41mm, its case was shaped according to older standards: thin lugs, polished bevel on the side of the case, non-protected oversized crown, aluminium insert for the uni-directional bezel. If the look was clearly vintage, the rest (quality, feel and dimensions) was entirely modern.

The matte black domed dial featured historical elements with gilt touches (gold-plated hands and indices, as well as gilded inscriptions), a vintage Tudor logo (the rose) and the iconic “Snowflake” hands. This combination of modern and vintage was the main reason for the success of this watch, alongside being an affordable alternative to the too-technical Submariner, which clearly?lacks some vintage appeal (according to some). Inside the case (at that time) was an automatic ETA movement.Several evolutions are to be noted: 2014: the introduction of the midnight-blue bezel, with silver-coloured indices and hands 2015: the introduction of the black bezel, with a gilt dial and a red triangle on the bezel 2016: the introduction of reference 79230, now with in-house calibre MT5602 (70h power reserve, COSC certification) on all 3 modelsIn addition to the evolutions listed above, which concern the main line-up, Tudor also played a lot with this collection by introducing a larger 43mm bronze version, a PVD-coated “Dark” edition, a two-tone steel-and-gold variant, a chronograph, a date edition with steel bezel as well as a sub-collection without a diving bezel, first shown in 36mm, later in 41mm and this year in 32mm. So, as you can see, the collection is quite complete! So what is the point of yet another edition, the new?Black Bay Fifty-Eight?The?Tudor Black Bay Fifty-Eight 39mmWhat is the?Tudor Black Bay Fifty-Eight 39mm? If the Black Bay 41mm was a modernised version of a vintage watch, the BB58 is a “vintaged” version of this watch… If you are having trouble following this sentence, this is normal. So give us a chance to make things clearer.The original Black Bay was a modern take on the vintage Submariner watches. While it relied on some clever visual tricks to make you believe it was a vintage watch, the overall concept was that of a modern watch, with modern proportions and modern quality. The diameter was larger, the case thicker, the bracelet modernly manufactured, the movement (especially the 2nd generation) truly contemporary… however, it also integrated multiple signature elements found on several vintage Submariner watches (Snowflake hands, domed dial, polished bevel on the side of the case, gilt dial, red triangle, riveted bracelet). In short, what we call a “revival watch” – the taste of vintage in a modern package.This year, Tudor comes with a “vintaged” version of this watch, with a smaller and thinner case, a slightly different movement and a dial/bezel that looks even more “aged” than in the past models. A modern interpretation of a vintage watch, the Black Bay Fifty-Eight now comes closer than ever to the original Submariner watches (from Tudor or ), both in terms of style and proportions.The main problem is that this watch doesn’t replace the existing 41mm version but comes in addition to the already large collection (comprising over 50 references). If the idea was to create confusion, this couldn’t have been done in a better way. So, face-to-face, how do the BB58 and the 41mm compare?Face-to-Face: Similarities and DifferencesPreliminary note: in order to illustrate the differences and similarities between the?Black Bay Fifty-Eight and the standard 41mm model, we relied on a 1st generation version of the 41mm version (ETA-powered, non-riveted bracelet, “smiley” dial). Since 2016, the 41mm version has been updated with a slightly different dial, a riveted bracelet and, of course, Tudor’s manufacture movement. This won’t have a huge influence on this comparison, with the exception that the 2nd generation with an in-house calibre is slightly thicker.When placed side by side, and at first sight, these two watches look very similar. The overall design of the case is the same and is the overall design of the dial and bezel. However, looking more closely, it’s easy to spot major differences – and even more when you strap both watches on the wrist.As for the case, the?Black Bay Fifty-Eight hasn’t only shrunk in diameter, from 41mm to 39mm, every single part of the watch has been reduced to offer new proportions. While the diameter is reduced by 2mm, the reduction in thickness is even more blatant. The BB41mm with manufacture movement is approximately 15mm in height – clearly not what we could call an ultra-thin, even for a dive watch. This has always been our main complaint about this watch at MONOCHROME. This is further reinforced by the shape of the case itself, with straight casebands that cover the entire thickness of the watch.With the BB58, Tudor has shaved off no fewer than 3 millimetres, to achieve an overall thickness of 11.9mm – which, in other words, represents a 25% reduction. In addition to that, the case has a slightly different shape, and part of the thickness of the movement is now absorbed by a bubble-like caseback, making the casebands even thinner. The overall sensation on the wrist feels like a return to the original proportions of a vintage Submariner – a watch that always wore thinner than its specifications led you to believe.To achieve this, Tudor has substituted the movement for the new calibre?MT5402. While the calibre?MT5602 found in the 41mm measures?31.8mm x 6.5mm, the new movement is now?26mm in diameter and 4.99mm in height. For the rest, the technical base is identical – 70h power reserve, anti-magnetic escapement, COSC-certification. So reduced diameter, reduced thickness, more compact case dimensions… What else? As we mentioned, every part of the watch has been resized to create harmonious and more vintage proportions, which includes the thickness of the lugs – more tapered, more curved and thinner – as well as the width of the bracelet – previously 22mm and now 20mm.All in all, this creates the impression of having two different watches on the wrist, with the BB58 being the closest to the original proportions of a vintage Sub. Comfort is, in our opinion, better on the BB58 because the watch feels more balanced. However, keep in mind that it won’t necessarily be the case for all of you. Only a test in a boutique will tell you which one fits you best.As for the rest of the watch, the only real difference is on the bezel, which now has “gilt” markings – golden inscriptions over a black background. The dial, the hands and the inscriptions have also been resized to match the new diameter of the watch, however, these are simply impossible to notice. And that might be the main issue here. Tudor could have given the BB58 a slightly different personality to help differentiate both references.Verdict – Which to choose?The easy answer would be “whichever one you prefer”.? However, let me give you a few more thoughts. I would say that everything depends on your taste and, more importantly, on the size of your wrist. For someone like me, with a 17cm wrist, I’d recommend going for the Black Bay 58. It will look more balanced, more elegant and will have more “vintage” impact than the 41mm version – which I own and love.If you have a solid wrist – let’s say over 19cm – the Black Bay 41mm won’t be a problem… but neither will the BB58. In both cases, it will depend on your taste in watches and your appetite for vintage. I know that some collectors/enthusiasts prefer large, masculine and robust watches, especially when it comes to dive watches. For those, the BB 41mm is a strong candidate.One last category of potential buyers for the BB58 could well be vintage collectors who’d like to add a modern, solid watch to their collections and have a daily-beater they can rely on. Certainly, they will be pleased by the 58, as it comes really close to what a Submariner was back in the 1960s.Our best advice is: go and try it on! Nothing beats trying a watch on the wrist. In any case, there’s no bad option, just choices. One thing for sure is that Tudor doesn’t help us make decisions! Sometimes, too many options create confusion – as good as those options might be.
