Miranda offers a fresh perspective on the Tudor Black Bay Reference 79733N, focusing on its luxurious yellow gold and steel iteration with a new champagne dial. This post, written after Baselworld, highlights the refined aesthetics and technical specifications of this two-tone diver, particularly its in-house Calibre MT5612 and the construction of its gold-capped bracelet.

Now that the dust has settled from Basel, we have a fresh look at TUDOR’s famous Black Bay divers’ in yellow gold and steel version with the new champagne dial and powered by the in-house manufacture Calibre MT5612.

In this version the lines and proportions of the Black Bay are retained, while the rotating bezel and the winding crown are made from yellow gold. The steel bracelet is also now classified as a true steel and gold as opposed to two tones. This is because the centre links whilst not being solid gold are gold capped. The gold is applied is sufficient amount that even several services and polishing’s later it will retain its desired appearance.
The new dial really takes this watch to another level, giving it a very luxurious appeal. I have to say the contrast is very significant compared to the black dial version. I much prefer this new look. I can see this new version appealing across both sexes.
The movement is of course in-house and features a very useful date function. A date in this watch works very well, as it not so much a tool watch but a luxury watch, albeit one that you could go diving in. The movement has an admirable 70 hour power reserve and beats at a frequency of 28,800 beats/hour or 4 Hz, the movement is regulated by a variable inertia oscillator with silicon balance spring. This is held in place by a traversing bridge, guaranteeing its robustness. Furthermore, the movement is certified by the Swiss Official Chronometer Testing Institute (COSC).






My overall impression was one of surprise as I am not so much into bi-metal, but this one really works. It is in my opinion one of the finest that I have seen and a good step into luxury sports.


The Tudor Black Bay reference 79733N introduces a two-tone aesthetic to the Black Bay diver's collection, combining yellow gold and steel. This reference maintains the established lines and proportions of the Black Bay series while integrating precious metal elements. It represents an expansion of the Black Bay's material offerings, moving beyond the initial steel and bronze iterations to include a more classic gold and steel presentation. The introduction of a champagne dial further distinguishes this particular configuration within the broader Black Bay family. This model is powered by a manufacture movement, underscoring Tudor's commitment to in-house calibers across its core lines. The rotating bezel and winding crown are crafted from yellow gold, providing a notable contrast to the steel case. The bracelet features steel and gold construction, with the center links incorporating gold, classifying it as a true steel and gold bracelet rather than a simple two-tone application. The crystal is sapphire, contributing to the watch's durability and legibility. This reference appeals to collectors seeking a Black Bay with a more luxurious material palette and a distinct visual presence. It offers an alternative to the more tool-watch oriented Black Bay models, providing a dressier option without departing from the collection's established design language. The champagne dial variant adds to the collectibility, offering a specific aesthetic choice within the two-tone range.
