The Tudor Black Bay 68 is the largest diver in the Black Bay range and the first of that line to carry METAS Master Chronometer certification — making it the strongest case Tudor has yet made for buyers who want genuine movement credentials alongside that iconic silhouette.
Unveiled at Watches & Wonders 2025, the Black Bay 68 takes the name from 1968, the year Tudor introduced its distinctive Snowflake hands on the Submariner. At 43mm in stainless steel, it is the biggest Black Bay Tudor has ever offered — 4mm wider than the beloved BB58 and 2mm beyond the BB41. What it earns with that size is the in-house MT5601-U calibre, the same METAS-certified movement that debuted in the Northflag GMT, now placed inside a no-date, no-nonsense 200m diver. If you want a bigger, better-specified Black Bay and are willing to forgo the riveted bracelet that defines the smaller models, the BB68 makes a compelling case.

TL;DR — Tudor Black Bay 68: METAS Muscle in a Bigger Case
The Black Bay 68 (ref. M7943A1A0NU) is a 43mm METAS Master Chronometer diver, available in sunburst silver or Tudor blue, on a three-link steel bracelet with T-Fit clasp — retailing at $4,700 USD at launch. Buy it if you want the largest Black Bay footprint, METAS-certified accuracy, and a clean no-date dial; skip it if you prefer the classic rivet bracelet of the BB58, a sub-40mm size, or a date window. It suits confident large-wrist buyers and collectors who want a tool-watch character that the smaller Black Bays cannot match.
What Is the Tudor Black Bay 68?
The Tudor Black Bay line began in 2012 as a single vintage-inspired diver. Over the years it expanded into a family spanning 37mm to 43mm, encompassing GMT, chronograph and no-date variants. The Black Bay 68 sits at the top of the size range, introduced in April 2025 as the brand’s most specification-forward standard diver to date.
The name “68” is a nod to 1968, the year Tudor first developed the Snowflake hands — the trapezoidal hour hands with a distinctive shaped tip — for use on the Submariner. Those hands have become one of Tudor’s most recognisable design signatures, appearing across the Black Bay family and cementing the brand’s identity as separate from its Rolex parentage. The Black Bay 68 wears them prominently on both its blue and silver dial variants. For more on Tudor’s history and how the brand built its own design language, see our history in 10 references.
What sets the BB68 apart from every other Black Bay is the movement inside it. The MT5601-U is the METAS Master Chronometer-certified version of Tudor’s manufacture calibre, meaning it has passed seven tests at the Contrôle Officiel Suisse des Chronomètres and at the Swiss Federal Institute of Metrology, achieving a standard significantly above ordinary COSC certification. Until the BB58 received its own METAS upgrade at Watches & Wonders 2026, the 68 was the only Black Bay diver to offer that certification at retail.
Case, Bezel and Build Quality
At 43mm in diameter and 13.6mm thick, the Black Bay 68 is substantial but not slab-sided. Tudor has kept the lug-to-lug proportions in check — the case wears somewhat smaller than the numbers suggest because the lugs are tightly integrated — and the 13.6mm height is actually thinner than the 41mm BB41’s 14.8mm profile. In other words, Tudor built a bigger watch that sits lower on the wrist than its immediately smaller sibling.
The case is brushed stainless steel with polished bevels on the lugs, giving the familiar Black Bay interplay of satin and shine. A screw-down crown sits flush against the right-side flank without crown guards, in keeping with the heritage aesthetic. The solid screw-in caseback is undecorated. Water resistance is rated to 200 metres, making it capable for recreational diving well beyond anything a typical buyer would ask of it.
The bezel is the key design departure from the BB58 and BB54. While those models carry a matte or ceramic insert with a red triangle at twelve o’clock, the BB68’s bezel has a coarsely knurled matte-black aluminium insert with no triangle and a more utilitarian, tool-watch feel. The knurling provides secure grip, and the unidirectional rotation with sixty-minute markings is precise. It is a deliberately different character — less heritage-sports, more functional diver — and will suit buyers who find the rivet bracelet and red triangle of the BB58 too nostalgic.
The bracelet is a smooth three-link Oyster-style in stainless steel with brushed and polished surfaces. Critically, it has no faux rivets — the design element that gives the BB58 its vintage appeal is entirely absent here. What you get instead is Tudor’s T-Fit clasp, which allows rapid half-link micro-adjustment without tools, and a secure double-folding mechanism. The 22mm lug width fits standard straps widely available from third-party makers.
Dials, Hands and Legibility
Two dial options are offered at launch: a sunburst Tudor blue and a sunburst silver. Both carry applied hour markers with Super-Luminova fills and the Snowflake hands that give the watch its name. Neither includes a date window, which keeps the dial uncluttered and maintains full symmetry — a deliberate choice that appeals to purists who find the magnified date of competing dive watches distracting.
The blue dial is the more immediately legible of the two, with strong contrast between the silver-toned hands and markers against the dark ground. The silver dial offers subtler legibility in standard lighting but catches light attractively, shifting from grey to warm champagne depending on the angle. Hands-on accounts from reviewers at launch were notably divided on which is more compelling: the silver is more understated and unusual for a sports diver; the blue is the more orthodox choice and the one that reads as a Tudor from across a room. Either way, the domed sapphire crystal — with Tudor’s signature bubbled profile — adds depth and a visual warmth that flat-crystalled competitors rarely match.
Movement: MT5601-U Master Chronometer
The MT5601-U is Tudor’s in-house manufacture calibre built by Kenissi SA, the Le Locle movement manufacturer co-owned by Tudor, Chanel, and Breitling, with Rolex holding a minority stake. It is the METAS-certified variant of the base MT5601, and clearing METAS certification requires every example to pass a seven-test protocol covering precision on multiple positions, power reserve, magnetic resistance, water resistance and more — conditions that exceed standard chronometer testing. For a full breakdown of Tudor’s calibre family, see our manufacture calibres explainer.
The result is a movement guaranteed to run between -2 and +4 seconds per day in normal conditions, and to maintain those tolerances after exposure to magnetic fields of up to 15,000 gauss. The silicon hairspring and variable-inertia balance wheel contribute both to that magnetic resistance and to long-term rate stability, since silicon is non-magnetic and requires no lubricant. Power reserve is 70 hours — two full days and change — set by a bidirectional rotor. The movement beats at 4Hz (28,800 vph) and carries 25 jewels, housed in a 33.8mm diameter plate.
In a market where METAS certification is associated primarily with Omega’s Co-Axial Master Chronometer watches at $5,000 and above, the MT5601-U brings equivalent independent certification to the Black Bay at the BB68’s launch price — and without the service cost of an escapement that requires factory-only tools. Tudor’s Kenissi calibre uses a conventional lever escapement that any authorised service centre can handle.

On the Wrist
The 43mm case places the BB68 firmly in large-wrist territory, but the 13.6mm height and the relatively tight lug-to-lug measurement mean it wears smaller than a 43mm from many competing brands. Wrists of 17cm and above will find it sits well; smaller wrists may feel overwhelmed, though individual tolerance for larger diameters varies significantly. The three-link bracelet lies flat without undue droop, and the T-Fit clasp allows precise adjustment — more so than the half-link-only setup on older Black Bay references.
Reviewers at launch noted that the bezel knurling provides a secure grip for dive-style operation, and that the domed crystal creates a pleasing sense of depth when viewing the dial from above. The absence of a date window means the crown can be shortened — it sits flush with the case rather than protruding for stem-set date adjustment — and the overall profile feels lean for a 43mm diver. On a rubber strap (the watch accepts any 22mm strap), it becomes a lightweight daily wearer; on the steel bracelet, it reads as a more substantial occasion piece.
Black Bay 68 vs the Black Bay Family
The Black Bay 68 does not exist in isolation. It sits alongside three other Black Bay diver variants, each with a distinct character, and the buying decision often comes down to size preference and how much movement certification matters. Here is how the range stacks up as of late 2026 — see our BB41 vs BB58 comparison for a deeper look at the two most popular competitors to the 68.
Tudor Black Bay 54 — 37mm, From $3,950
The smallest of the family at 37mm. Launched as a vintage-inspired tribute with a rivet bracelet option and one of Tudor’s slimmest case profiles, the BB54 suits buyers with smaller wrists or those who want the most wearable daily option. It runs COSC-certified movement and lacks METAS certification. The 2026 addition of a sunburst blue dial expanded its colour range. For most people who want a versatile, less imposing Black Bay, the BB54 is the best starting point.
Tudor Black Bay 58 — 39mm, From $4,975 (METAS)
The “Goldilocks” Black Bay and the most widely beloved in the family. Updated at Watches & Wonders 2026 with a METAS-certified movement and a marginally slimmer case (11.7mm), the BB58 now competes directly with the BB68 on movement credentials while remaining 4mm narrower on the wrist. Its rivet bracelet and cream Snowflake hands (on some references) give it more vintage personality than the 68, and its greater range of dial colours makes it the more versatile choice. The trade-off is price: the updated BB58 starts at $4,975, which puts it above the BB68’s 2025 launch price. If movement specification is your reason to choose METAS, the 68’s price advantage over the BB58 may be the deciding factor.
Tudor Black Bay 41 — 41mm, From $5,325 (COSC)
The BB41 is the largest Black Bay before the 68, but it is thicker (14.8mm) and remains on COSC certification rather than METAS. At $5,325 and above, it is also the most expensive non-chronograph Black Bay and does not justify its premium with a METAS movement. The BB68, if its price remains near the 2025 launch figure, offers superior movement credentials for less money in a similarly large case.
Tudor Black Bay 68 — 43mm, $4,700 (METAS)
The largest and most specification-forward. It earns the METAS badge without requiring a price premium over the BB41, keeps the case slim relative to its diameter, and offers a design that deliberately distinguishes it from the vintage-influenced BB54 and BB58. The downside: no rivet bracelet, fewer dial options, and a 43mm footprint that excludes buyers with average or smaller wrists.
| Model | Case | Cert | Price (Oct 2026) | Best For |
|---|---|---|---|---|
| BB54 | 37mm / 11mm | COSC | From $3,950 | Smaller wrists, vintage charm |
| BB58 | 39mm / 11.7mm | METAS | From $4,975 | Balanced size, most versatile |
| BB41 | 41mm / 14.8mm | COSC | From $5,325 | Heritage styling, larger wrist |
| BB68 | 43mm / 13.6mm | METAS | $4,700* | Tool-watch character, METAS at lower price |

Price, Availability and Resale Value
The Black Bay 68 launched in April 2025 at $4,700 USD, sitting between the COSC-certified BB41 and the range’s more expensive entries. It is a permanent collection piece, not a limited edition, so supply through authorised dealers is steady. Unlike Rolex, Tudor’s authorised dealers do not typically maintain waiting lists for Black Bay models — expect to walk in and buy, or to order with a short lead time at most retailers.
Grey-market pricing at launch sat slightly below retail, at approximately $4,000–4,300 USD per estimates from resale analysts — consistent with the modest secondary-market discount that applies to most in-production Tudor pieces. Tudor watches do not appreciate significantly at retail in the way that scarce Rolex references do, but they hold value well compared with many Swiss brands, particularly Black Bay models, which maintain strong collector recognition. For a detailed look at resale data across the Tudor range, see our piece on whether Tudor watches hold their value.
The Pelagos family occupies a different price tier; the Tudor Pelagos Buying Guide covers that range if you are comparing the BB68 to Tudor’s more technically sophisticated titanium diver.
Where to Buy
The Black Bay 68 is available through Tudor’s global network of authorised retailers. The watch itself is not sold through Amazon, which hosts only grey-market listings for Tudor at steep and unverifiable prices. If you want to experiment with aftermarket straps on the 22mm lug, current 22mm NATO and rubber straps on Amazon cover a wide range of styles and price points. Price checked as of October 2026.
The Black Bay 68 measures 43mm across its stainless steel case and 13.6mm in height. Despite the 43mm width — the largest in the Black Bay family — the case’s tight lug-to-lug span and slim profile mean it wears modestly for its size. Wrists of 17cm and above are the natural fit, though buyers with larger proportions regularly run bigger than that guideline comfortably.
METAS (Swiss Federal Institute of Metrology) Master Chronometer certification is a seven-test protocol covering accuracy in multiple positions, power reserve under load, magnetic resistance to 15,000 gauss, and water resistance. The BB68’s MT5601-U calibre is guaranteed to run between -2 and +4 seconds per day and to maintain that rate after exposure to strong magnetic fields — a notably higher standard than standard COSC chronometer testing.
No. The Black Bay 68 displays hours, minutes and seconds only, with no date complication. This keeps the symmetry of the dial intact, allows the crown to sit shorter against the case, and appeals to collectors who prefer an uncluttered dial. If a date is important to you, the Black Bay 41 and Black Bay GMT S&G both offer that complication within the wider Black Bay family.
The BB58 is 4mm narrower (39mm vs 43mm), received its own METAS-certified movement at Watches & Wonders 2026, offers a rivet bracelet option, and has a wider range of dial colours. Updated BB58 pricing starts from $4,975, which is above the BB68’s 2025 launch price. The BB68 is the better pick if you want a larger case; the BB58 suits buyers who value the vintage rivet bracelet and smaller footprint.
The Black Bay 68 has a 22mm lug width. Standard 22mm straps — NATO, leather, rubber or mesh — fit the watch directly. Tudor sells official rubber and leather straps through its dealer network. Third-party 22mm options from makers such as Everest, Rios, and various NATO suppliers also fit, and Amazon’s selection of 22mm straps covers most preferences and budgets.
No. The Black Bay 68 is a permanent collection piece in two dial variants (blue and silver). Tudor does not limit production, and the watch is available through authorised dealers worldwide without waiting lists. This also means secondary-market prices sit slightly below retail, which is common for in-production Tudor models.
Tudor revealed the Black Bay 68 at Watches & Wonders 2025, held in Geneva in April 2025. It entered retail immediately after the show. The “68” designation references 1968, the year Tudor introduced its iconic Snowflake hands on the Submariner — a design element that has defined the brand’s diver identity ever since.
Final Verdict
The Tudor Black Bay 68 is a confident, clearly defined piece that occupies a niche no other Black Bay fills: a 43mm no-date diver with METAS certification and a tool-watch aesthetic that keeps its distance from the family’s vintage-influenced models. At its April 2025 launch price of $4,700, it offered METAS credentials below the cost of the updated BB58 — a genuinely interesting proposition for a buyer who values certified movement performance over bracelet nostalgia.
Buy it if: you want the largest Black Bay, you prioritise METAS certification, you prefer the clean bezel and no rivet links, and you have a wrist to fill a 43mm case. Do not buy it if: you want a date, the rivet bracelet, or a sub-40mm size. The BB58’s 2026 METAS upgrade has closed the specifications gap, but the BB68 retains the advantage of size and — if its retail price has not matched the BB58’s increase — value. Confirm current pricing with a Tudor authorised dealer, then try it on: the 68 rewards a proper fit more than most numbers-on-paper comparisons suggest.
