The Longines Ultra-Chron Carbon boldly reimagines the brand’s ‘60s-era Ultra-Chron, blending classic design with cutting-edge materials and modern aesthetics. For the first time, Longines introduces a carbon case to the Ultra-Chron lineup, offering a sleek, matte finish that contrasts the watch’s clean monochrome design. The unique construction of the case—crafted from a layered mix of unidirectional carbon fiber and epoxy resin—creates smooth, flowing striations, accentuating the watch’s linear features and chamfered edges.
The Ultra-Chron Carbon’s bezel has a fixed titanium construction and a 60-minute matte black aluminum insert. This new bezel design embraces a minimalist approach with five-minute markers, a departure from past models’ more complex rotating bezels. Despite the change, the Longines Ultra-Chron Carbon retains an impressive 300 meters of water resistance, thanks to its titanium crown and solid caseback.
Inside, the L836.6 automatic movement beats with a high-frequency 36,000 bph rate, providing exceptional accuracy and a 52-hour power reserve. The watch is chronometer-certified by TIMELAB, ensuring top-tier performance at a competitive price point. Fitted with a black fabric strap and titanium buckle, Longines’ Ultra-Chron Carbon is a sleek, durable timepiece that pushes boundaries while offering unbeatable precision. At $4,900, it’s a standout in modern dive watches.
