Unworn, Tudor Black Bay Chrono “Carbon 25”, Ref#79377KN-0001, box and papers

The Tudor Black Bay Chrono “Carbon 25” M79377KN-0001 is a striking limited-edition chronograph that pushes the boundaries of traditional sport watch design with cutting-edge materials and motorsport-inspired aesthetics. Crafted in a 42 mm redesigned carbon fibre case with a fixed carbon fibre bezel and tachymetric scale, this bold timepiece reflects performance and technical ambition, mirroring the Visa Cash App Racing Bulls Formula One Team livery in its “racing white” dial with contrasting luminous black counters — a tribute to Tudor’s long connection with motorsport. At its heart beats the Manufacture Calibre MT5813 automatic chronograph movement, certified by COSC and equipped with a bidirectional rotor system and ~70-hour power reserve, ensuring robust precision and reliability. The domed sapphire crystal and white dial with date at 6 o’clock enhance both legibility and style, while PVD-finished screw-down crown and titanium pushers reinforce the technical character. Paired with a hybrid leather-rubber strap featuring a distinctive “tire pattern”, this chronograph combines sporty flair with comfort and versatility. The Black Bay Chrono “Carbon 25” is a limited edition that stands out in both performance and design. The watch is unworn in like-new condition, comes with box and papers, and includes warranty documents dated, offering a rare opportunity to own a pristine collector-ready Tudor timepiece.
