The Black Bay Pro Gets Brighter: Introducing The Opaline Dial Variant
Tudor expands its Black Bay Pro lineup with the introduction of an opaline dial, bringing a bright and highly legible alternative to the original matte black dial version released in 2022. This new variant maintains the same core specifications that define the Black Bay Pro as a robust and versatile GMT sports watch.

Case and Bezel
The Black Bay Pro continues to feature a compact 39mm stainless steel case with a thickness of 14.6mm. Its lug width remains at 20mm, ensuring compatibility with a wide range of straps and bracelets. The case is finished with a satin-brushed texture, offering a tool-watch aesthetic that complements its utilitarian design. Retaining the fixed 24-hour bezel in brushed stainless steel, the model remains true to its travel-friendly functionality, allowing for easy tracking of a second time zone. Built for durability, the Black Bay Pro maintains a water resistance rating of 200 meters (660 feet), making it suitable for various outdoor and aquatic activities.

Dial and Hands
The new opaline dial enhances legibility with a crisp, off-white surface that provides strong contrast against the black-outlined applied markers and the signature “Snowflake” hands. The markers and hands are filled with Grade A Super-LumiNova, ensuring optimal visibility in low-light conditions. A yellow 24-hour hand allows for quick reference of the additional time zone, complementing the GMT functionality.

Movement and Performance
Powering the Black Bay Pro is Tudor’s in-house caliber MT5652, an automatic movement featuring a full “flyer” GMT function. This means that the local hour hand can be independently adjusted without stopping the movement, making it particularly useful for frequent travelers. The movement operates at a frequency of 4 Hz (28,800 vibrations per hour) and provides an impressive power reserve of approximately 70 hours. Additionally, the instantaneous date change is tied to the local hour hand, ensuring seamless adjustments across time zones.
Strap Options
Tudor offers three strap options for this release: a riveted stainless steel bracelet, a black Jacquard fabric strap with a yellow accent, and a hybrid rubber-and-leather strap for added versatility.
Conclusion
The Tudor Black Bay Pro with an opaline dial retains all the technical capabilities of its predecessor while introducing a fresh, high-contrast aesthetic. Its combination of a compact case, flyer GMT movement, and robust build quality continues to position it as a strong contender in the sports watch category, offering a practical and well-executed alternative for enthusiasts seeking a travel-ready timepiece.
