Description
The 2025 Tudor Black Bay Chrono, reference 79377KN, often also referred to as the limited “Carbon 25” edition, marks a thoroughly modern, sporty and technical milestone in the history of the Black Bay collection. It combines the brand’s motorsport-inspired chronograph architecture with state-of-the-art, ultralight high-tech materials. Made from a high-strength composite material, this watch stands out with its radical matte-black appearance and uncompromising performance for sporting use.
Featherlight 41 mm composite-material (Carbon) case: Crafted from an advanced carbon-fiber composite with a matte finish. The material significantly reduces weight, offers exceptional scratch resistance and gives the watch a distinctive satin-matte texture.
Fixed Carbon tachymeter bezel: The integrated bezel with an engraved tachymeter scale underscores the chronograph’s motorsport character and blends seamlessly with the monolithic case design.
Matte-black dial with contrasting totalizers: The deep, anti-reflective “Panda”-style dial features two vertically arranged subdials in a striking contrasting color (Small Seconds at 9 o’clock and a 45-minute chronograph counter at 3 o’clock), as well as distinctive luminescent indices.
Date window at 6 o’clock: Discreetly and functionally integrated into the lower half of the dial, it preserves the dial’s aesthetic symmetry.
Manufacture Chronograph Calibre MT5813 (COSC-certified): Powered by a high-performance manufacture movement with automatic winding, column-wheel control and a vertical clutch. The movement operates at a frequency of 28,800 vibrations per hour (4 Hz) and offers an impressive power reserve of approximately 70 hours, as well as a paramagnetic silicon hairspring.
Scratch-resistant Sapphire Crystal: A flat, double-sided anti-reflective Sapphire Crystal reliably protects the dial from impacts and reflections.
Screw-down crown and pushers: The PVD-coated controls, made of stainless steel, ensure reliable water resistance in combination with the solid case back.
Reliable water resistance (200m / 20 ATM): Offers the high robustness typical of Tudor and unrestricted suitability for diving and sports.
Integrated Textile or rubber strap: Fitted with a durable matte-black rubber strap or a black Textile strap made using traditional jacquard craftsmanship, secured by a sturdy black PVD-coated Folding Clasp.
Radical high-tech sports watch (2025): Reference 79377KN is a modern, uncompromising interpretation of the Black Bay Chrono – technologically advanced and defined aesthetically by pure, functional aggression.
