The TUDOR Black Bay 68 is a 43mm stainless-steel watch offered with blue or silver dials. Its size is the defining difference implied by “68,” but published dimensions alone cannot establish how it will wear on your wrist. TUDOR lists a 13.6mm thickness, 22mm lug width, 200m water resistance and a 70-hour power reserve for the blue model; its U.S. suggested retail price is $5,475.
This is a specifications-led look, not a physical review: there are no firsthand fit, comfort, accuracy or water-test observations to report.
What makes the Black Bay 68 different?
The Black Bay 68 brings a 43mm case to the Black Bay family. That diameter makes it a larger-format option within the line, but it does not by itself show how the watch will sit on a particular wrist. TUDOR’s family page presents the model in two dial colors, blue and silver, and connects its name to the history of the Snowflake hand.
TUDOR says it conceived the Snowflake hand in 1968 and added it to the catalogue in 1969. Those are distinct milestones: the “68” refers to the conception date in the brand’s account, not the catalogue introduction. The 1969 date is also reported in Hodinkee’s April 1, 2025 launch coverage.

Blue and silver: what changes visually?
The blue version pairs a sun-brushed TUDOR Blue domed dial with applied markers and a matte black aluminium bezel insert. The silver version provides the alternative dial color. Both are listed by TUDOR as Black Bay 68 variants, but the available specifications here do not establish detailed differences in the silver dial’s finish or other component specifications. The bracelet is a three-link steel design with a T-fit clasp.
On the blue reference, the black insert creates a distinct dark frame around the blue dial, while the steel bracelet keeps the overall combination monochrome beyond the dial. These are descriptions of the published design, not observations of a handled example.

How does the Black Bay 68 wear—and is it too big?
There is no responsible yes-or-no fit verdict from the published measurements alone. Diameter, thickness and lug width are known, but an actual lug-to-lug measurement and wrist-specific wear observations are not established here. A 43mm case may be a useful warning for someone who usually prefers smaller watches, but it cannot settle whether the lugs overhang, whether the case feels top-heavy, or whether the watch is comfortable.

Before deciding, compare the 43mm diameter and 13.6mm thickness with a watch you already wear, then try the Black Bay 68 on your wrist if possible. Pay attention to lug overhang, how the case sits when your wrist bends, and whether the bracelet can be adjusted securely. TUDOR’s family-page phrase, “Now, with the Black Bay 68, there’s a Black Bay for everyone,” is brand positioning—not evidence that the model fits every wrist.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Who should consider it?
- Consider it if you want a larger Black Bay, like the blue or silver dial options, and value the listed 200m water resistance and 70-hour reserve.
- Try it before buying if your concern is fit. The 43mm diameter and 13.6mm thickness are useful screening figures, not substitutes for seeing how the case and bracelet sit on you.
- Check the details that matter to you against TUDOR’s current product information, especially price, availability and the specifications of the silver reference.
TUDOR says its watches are sold through Official Retailers. Verify a seller’s status with TUDOR rather than assuming a marketplace listing is authorized.
