The story behind this Tudor Black Bay
Tudor has had a connection with motorsport since the launch of the Oysterdate chronographs in the early 1970s. The Tudor Black Bay Chrono 79377KN model incorporates a unique technical dimension through the use of composite materials. The introduction of matrix carbon at Tudor meets the need for lightness and robustness. The case back, engraved with a chequered pattern, evokes the world of motor racing. This numbered edition combines the brand’s aesthetic heritage with a contemporary design.
Case, movement and strap of this Black Bay
The 42 mm diameter case is machined from a matt black carbon composite, revealing the greyish marbling inherent in the material. The fixed bezel features a white tachymeter scale for measuring speeds. Beneath the flat sapphire crystal lies a pure white dial, contrasted by two recessed carbon sub-dials housing the chronograph minutes and small seconds. The whole is complemented by Snowflake hands coated with luminescent material. A date window displays the date at 6 o’clock. The watch is powered by the MT5813 calibre, certified as a chronometer by the COSC. This automatic movement offers a 70-hour power reserve and beats at a frequency of 28,800 vibrations per hour. Water resistance is guaranteed to 200 metres thanks to a screw-down crown and pushers made of titanium. The black hybrid strap combines a rubber base with a textured upper layer featuring white stitching and fastens with a folding clasp.
Why this Tudor watch
The appeal of this timepiece lies in its strict limited edition of 2,026 pieces worldwide. The number engraved on the caseback confirms its place in this limited series. The choice of a ‘panda’ dial on a carbon case creates a striking visual contrast. The combination of a high-performance movement and a discreet, technical design makes this model a sought-after item on the second-hand market.
