The Tudor Black Bay 41 and Black Bay 58 share the same pedigree, the same 200-metre dive credentials, and the same METAS-certified movement quality — yet they are meaningfully different watches built for different wrists and wardrobes.
Updated October 19, 2026. In the crowded world of Swiss sport watches, Tudor’s Black Bay line is the rare case where two similar models coexist without one making the other redundant. The BB41 and BB58 share a family face — that iconic domed bezel, applied indices, bold crown — but beneath the aesthetic kinship are real differences in how they sit on the wrist, how they pair with clothing, and how they serve different lifestyles. For context on how these models fit into Tudor’s broader story, see our Tudor history in 10 references and the Tudor brand hub.
Quick take
- Black Bay 41 — 41 mm / 14.8 mm thick, bold presence, ~$5,075–$5,450 in steel
- Black Bay 58 — 39 mm / 11.9 mm thick, remarkably slim for a diver, ~$4,975–$5,350 in steel
- Both: METAS-certified, 70-hour power reserve, 200 m water resistance, silicon hairspring
- Pick the BB41 for a modern 41 mm footprint and 7½-inch-plus wrists
- Pick the BB58 for dressability, smaller wrists (6–7.5 in), and far slimmer profile

What Are These Watches?
Tudor’s Black Bay line traces its roots to the 1958 Tudor reference 7924, one of the brand’s early professional dive watches. The modern Black Bay family relaunched in 2012 and has since grown to cover multiple sizes and complications under a unified vintage aesthetic.
The Black Bay 41 is the standard current-size interpretation: 41 mm puts it in line with today’s norms for a serious sport watch. Its movement, the MT5602, is a METAS-certified in-house calibre that Tudor developed to compete directly with anything offered by brands charging considerably more.
The Black Bay 58 (the name nods to that 1958 ancestor) arrived in 2018 with a deliberate brief: to deliver the full Black Bay experience in a smaller, slimmer package. At 39 mm, it is closer in spirit and proportion to vintage Tudor submariners. Recent updates brought METAS certification to both models. Both are in-house movements with a silicon hairspring — a combination that, at this price, remains a genuine engineering achievement.
Design and Dial Options
On paper, the BB41 and BB58 look nearly identical: the same bi-directional ratcheting bezel with aluminium insert, the same domed sapphire crystal with anti-reflective coating, the same oversized Tudor crown, and the same snowflake hour and minute hands with syringe-style lume indices.
The key visual difference is the seconds hand. The BB58 carries a “lollipop” seconds hand — a disc-on-a-stick design lifted from vintage Tudor submariners — that gives it a more overtly retro character. The BB41 uses a conventional tapered baton seconds hand. It is a subtle distinction in photos, but visible in person.
Both watches are offered in black or burgundy dials. The BB58 goes further: it is also available in bronze (with a unique brown-toned bronze case and bracelet) and sterling silver editions, broadening its appeal well beyond the standard steel offering. The BB41, for now, remains a steel-only proposition. Both come with a rubber strap and an Oyster-style steel bracelet included in the box, and a Jubilee-style five-link bracelet is available as an option on both.
Size on the Wrist
This is where the real differences live. The numbers tell part of the story:
| Specification | Black Bay 41 | Black Bay 58 |
|---|---|---|
| Case diameter | 41 mm | 39 mm |
| Thickness | 14.8 mm | 11.9 mm |
| Lug-to-lug | ~50 mm | ~47 mm |
| Lug width | 22 mm | 20 mm |
| Water resistance | 200 m | 200 m |
The thickness gap is the headline. At 14.8 mm, the BB41 is a substantial watch — you feel it on the wrist, and it will not tuck under a dress-shirt cuff without a visible bulge. That is not unusual for a tool diver — the Rolex Submariner is 12.9 mm, the Omega Seamaster Diver 300M is 13.6 mm — but it is noticeable in everyday wear.
The BB58 at 11.9 mm is remarkable for what it is. For a 200-metre-rated diver with a rotating bezel, a sapphire crystal, and a robust crown-and-gasket system, that is genuinely slim. It can wear under a cuff on a thinner dress shirt — not invisibly, but far more discreetly than the BB41.
The lug-to-lug difference (50 mm vs 47 mm) matters more than the 2 mm diameter gap. If your wrist is under 7 inches, the BB41 will overhang noticeably. The BB58’s ~47 mm L2L makes it the more broadly wearable watch. For a closer look at each model independently, see our Tudor Black Bay 41 review and Tudor Black Bay 58 review.
Movement and Specs
Tudor’s METAS certification is meaningful. It covers testing in six positions under water-resistant conditions and guarantees daily accuracy within −4/+6 seconds at 200-bar magnetic field resistance. That is a step beyond the COSC chronometer standard and places Tudor’s movements alongside Omega’s Co-Axial Master Chronometer in terms of real-world testing rigour.
| Movement spec | BB41 (MT5602) | BB58 (MT5400) |
|---|---|---|
| Beat frequency | 28,800 vph (4 Hz) | 28,800 vph (4 Hz) |
| Power reserve | 70 hours | 70 hours |
| Certification | METAS | METAS |
| Silicon hairspring | Yes | Yes |
| Water resistance | 200 m | 200 m |
The silicon hairspring on both calibres delivers improved antimagnetic resistance and eliminates the need for hairspring lubrication. In practical terms, both movements deliver the same quality, accuracy and reliability. Servicing intervals are similar, and Tudor’s official service network is well established across major markets.
If you are upgrading from a quartz watch or an entry-level automatic, either movement will feel like a step change. There is no meaningful reason to choose one over the other on movement grounds alone.
Price, Availability and Resale
Both watches land within about $100 of each other for comparable steel configurations:
- BB41: $5,075 (rubber strap) / $5,450 (steel bracelet)
- BB58: $4,975 (rubber strap) / $5,350 (steel bracelet)
The BB58 is marginally cheaper, but the gap is negligible. Where the BB58 pulls ahead on value is material optionality: the bronze edition ($5,850) and sterling silver edition ($5,600) are unavailable on the BB41.
Both models are widely stocked at authorised Tudor dealers worldwide. Neither carries the artificial scarcity of a Rolex or a Patek, meaning you can walk into a decent retailer and buy one at retail price today. On the secondary market, grey-market prices typically track within 5–10% of retail for both, making Tudor one of the more honest propositions in Swiss watchmaking.

The Competition
The BB41 and BB58 don’t exist in a vacuum. Here is how they sit against the main alternatives in the $4,000–$10,000 sport-watch segment:
| Watch | Price (steel) | Diameter | Thickness | Certification |
|---|---|---|---|---|
| Tudor Black Bay 41 | $5,075–$5,450 | 41 mm | 14.8 mm | METAS |
| Tudor Black Bay 58 | $4,975–$5,350 | 39 mm | 11.9 mm | METAS |
| Tudor Black Bay 36 | $3,775+ | 36 mm | 11.7 mm | COSC |
| Omega Seamaster 300M | $5,800–$6,200 | 42 mm | 13.6 mm | METAS |
| Rolex Submariner | $9,700+ (retail) | 41 mm | 12.9 mm | COSC |
The Omega Seamaster Diver 300M is the closest direct competitor to the BB41 by size and price, and — like Tudor — it offers METAS certification. It is slightly more expensive but adds Co-Axial escapement technology. The Rolex Submariner commands nearly double the retail price for specification parity that most buyers cannot justify beyond the brand premium.

Who Should Buy Each
Buy the Black Bay 41 if: your wrist measures 7 inches or more; you prefer the definitively modern 41 mm footprint; you often wear it with casual or sport outfits where thickness is a non-issue; and you want a watch that commands attention without apology.
Buy the Black Bay 58 if: your wrist is under 7 inches, or you simply prefer a more compact feel; you regularly wear a watch under a dress-shirt cuff; you want material options beyond steel (bronze, silver); you appreciate the vintage lollipop seconds hand; or you want 20 mm lugs, where aftermarket strap options are effectively unlimited.

Frequently Asked Questions
The two biggest differences are case size and thickness. The BB41 is 41 mm wide and 14.8 mm thick; the BB58 is 39 mm wide and just 11.9 mm thick — almost 3 mm slimmer, which is significant on the wrist. The BB58 also features a vintage ‘lollipop’ seconds hand referencing 1950s Tudor submariners. Movement quality, water resistance, and retail price are nearly identical between the two models.
The Black Bay 58 is the better fit for wrists under 7 inches. Its ~47 mm lug-to-lug measurement sits comfortably on wrists from around 6 to 7.5 inches without overhanging the edges. The BB41’s ~50 mm lug-to-lug will extend past the wrist on most smaller or medium wrists.
No. As of late 2026, the Black Bay 41 remains a current production model in Tudor’s catalogue, available in black and burgundy dial variants on rubber strap or Oyster steel bracelet. It has not been discontinued or put on a watch list.
Yes. Both the BB41 and BB58 are rated to 200 metres water resistance, which covers recreational scuba diving and all surface water activities. The screw-down crown and tested gasket system make either model a genuine tool diver, not just an aesthetic interpretation of one.
They serve different buyers. A Seiko Prospex diver can be purchased for under $1,000 with solid mechanical quality. The BB58 at around $5,000 adds an in-house METAS-certified movement, sapphire crystal, greater finishing quality, and Swiss provenance. If budget is the priority, Seiko wins comfortably. If movement pedigree, long-term value retention, and brand longevity are part of the equation, Tudor is the stronger proposition.
Tudor holds its value better than most Swiss brands at this price level. Grey-market prices for both the BB41 and BB58 typically trade within 5–10% of retail, compared to many competitors that trade at 20–40% below. Neither model is a strong appreciation investment comparable to a Rolex Submariner, but Tudor rarely punishes buyers who need to sell.
Final Verdict
On pure spec-for-spec comparison, the Black Bay 58 is the more practical choice for more people. It is thinner, fits a wider range of wrist sizes, comes in more material options, and costs fractionally less — all while offering the same movement quality and dive credentials as the larger watch. The 11.9 mm thickness is genuinely impressive in a 200-metre diver and sets it apart from almost every competitor at this price.
But the BB41 has its own case. At 41 mm it occupies the modern sweet spot for a sport watch; it wears as a statement rather than a subtle accessory. If you want a watch that fills the wrist and reads unambiguously as a serious diver, the BB41 delivers that in a way the BB58 simply doesn’t.
The best advice is the oldest one in watch buying: try both on if you can. A 2 mm difference in diameter and 3 mm in thickness reads very differently on different wrists. If your local authorised Tudor retailer has both in stock — and most do — put them on back-to-back. The choice usually becomes obvious within 30 seconds.
