The history of this Tudor Black Bay Chrono
The House of Tudor draws on a technical heritage rooted in the history of sports watchmaking. This watch, reference 79310N, belongs to the Black Bay Chrono 39 family. It illustrates the brand’s ability to adapt its iconic designs to current expectations by offering a more compact format than previous generations. The model was developed to provide a functional and legible alternative to classic sports chronographs. Tudor has preserved its identity by integrating historic aesthetic elements while offering a deliberate colour palette with this yellow dial. This colour choice marks a stage in the evolution of the line by favouring strong contrast without compromising legibility. The watch responds to a need for versatility by combining a distinctive aesthetic with a robust architecture intended for daily use.
Case, calibre and bracelet of this Black Bay Chrono
The 39 mm stainless steel case offers balanced proportions that ensure a discreet presence on the wrist. The surfaces alternate satin and polished finishes with the regularity characteristic of the brand’s work. A fixed black anodised aluminium bezel bears a white tachymetric scale allowing speed measurements to be taken. The matte yellow dial features two black azuré sub-counters at 3 o’clock and 9 o’clock, ensuring clear reading of the chronograph functions. The ensemble is powered by calibre MT5813, an automatic manufacture movement with a 70-hour power reserve. This movement is equipped with a column wheel and vertical clutch for smooth activation of the timing functions. The oscillation frequency is set at 28,800 vibrations per hour. The watch is water-resistant to 200 metres and features a screw-down crown ensuring its security. The steel bracelet is equipped with a T-fit clasp allowing quick length adjustment without tools. A domed sapphire crystal protects the dial and reinforces the functional character of this instrument.
Why this Tudor watch
The Black Bay Chrono 39 represents an interesting piece for the watch enthusiast seeking a singular configuration. This model is less common on the market than classic monochrome versions, and its 39 mm format makes it more accessible for various wrist types. At The Swiss Collector, we selected this piece for its mechanical coherence and dynamic aesthetic, which needs no artifice to assert itself. It constitutes a relevant option for enriching a collection with a reliable and technically accomplished chronograph. Its price positioning and immediate availability make it a considered alternative to the often long wait in official boutiques.
