The story behind this Tudor Black Bay Chrono
With this chronograph, Tudor presents an evolution of its technical heritage. This model blends the worlds of scuba diving and motor racing. The M79360N-0024 stands out thanks to its matt turquoise-blue dial. Historically accustomed to using dark colours for its tool watches, the brand is here responding to a specific demand for distinctive pastel shades. The introduction of this shade marks an aesthetic departure. This choice affirms the manufacture’s desire to modernise its visual approach whilst maintaining the exacting mechanical standards that form its foundation. It is said that this chromatic shift responds to the global craze for brightly coloured dials pioneered by the major watchmakers. Tudor incorporates this trend with haute horlogerie specifications.
Case, calibre and strap of this Black Bay Chrono
The timepiece features a stainless steel case measuring 41 mm in diameter. The design features alternating polished surfaces on the sides and a straight-grained finish on the upper part of the lugs. The whole is encircled by a fixed bezel fitted with a matt black aluminium insert featuring a tachymeter scale. The turquoise dial features two black sub-dials with a recessed concentric circle pattern. These sub-dials are dedicated to the small seconds at 9 o’clock and the 45-minute counter at 3 o’clock. A recessed date window is positioned at 6 o’clock. The applied hour markers and hands feature a green luminescent coating. The fluted crown and the two cylindrical pushers are screw-down to ensure water resistance certified to 200 metres. The functions are powered by the MT5813 calibre. This automatic movement oscillates at a frequency of 4 Hz. It offers a power reserve of 70 hours. The mechanism incorporates a column wheel and a vertical clutch for chronometric precision certified by the COSC. The internal architecture is supported by 41 jewels. The watch is worn on a 5-link steel bracelet with a clasp featuring a quick-adjustment system.
Why this Tudor watch
The appeal of this piece on the pre-owned market lies in the uniqueness of its two-tone design. The combination of a matt turquoise dial with black sub-dials creates a striking contrast on a contemporary technical chronograph. This specific model is distributed on a very limited basis within the brand’s official network. Acquiring this example allows you to add a hard-to-find version to your collection whilst benefiting from the reliability of a robust in-house calibre. Demand for this pastel variant remains high amongst enthusiasts seeking an alternative to classic models.
