Longines introduces the Ultra-Chron Carbon, combining over 50 years of heritage with cutting-edge materials and precision engineering.
A Legacy of High-Frequency Innovation
Longines’ Ultra-Chron line has been a cornerstone of precision watchmaking since its debut in 1966. The original Ultra-Chron ref. 7827 introduced the world to mass-produced, high-frequency mechanical watches. Powered by the groundbreaking Longines caliber 431, it operated at an impressive 5Hz (36,000 vibrations per hour). The result? A precision guarantee of two seconds per day, a feat achieved through innovative dry lubrication techniques.
In 1968, the Ultra-Chron Diver made history as the first high-frequency diver’s watch. Its 41mm stainless steel cushion case, water-resistant up to 200 meters, combined durability and precision. Decades later, in 2022, Longines revived this iconic series with a modernized Ultra-Chron Diver that retained the cushion-shaped design but increased water resistance to 300 meters. It featured the caliber L.836.6 movement, adhering to ISO 3159 chronometer standards.
Introducing the Ultra-Chron Carbon
The Ultra-Chron Carbon continues this storied tradition, pushing boundaries with innovative materials. Its standout feature is a 43mm cushion-shaped case crafted from unidirectional carbon fiber and epoxy resin—a first for Longines. This aerospace-inspired material offers superior impact resistance, corrosion resistance, and durability while weighing less than 80 grams, including the strap.
Each case is visually unique due to random carbon fiber patterns formed during the manufacturing process. The watch is complemented by a fixed titanium bezel with an aluminum insert engraved in 10-unit increments, adding to its modern aesthetic.
High-Performance Movement
The Ultra-Chron Carbon is powered by the exclusive Longines caliber L.836.6. This self-winding mechanical movement operates at a high frequency of 5Hz, ensuring exceptional precision and a smooth sweeping second hand. Its lightweight, antimagnetic silicon balance spring offers magnetic resistance 10 times greater than the ISO 764 standard, safeguarding accuracy in challenging environments.
Certified Precision
Longines subjected the Ultra-Chron Carbon to TIMELAB’s stringent 15-day certification process in Geneva. This rigorous testing exceeds standard chronometer benchmarks, ensuring the watch meets ISO 3159 standards for unparalleled precision.
Design Meets Function
The Ultra-Chron Carbon boasts a sand-blasted anthracite dial with applied silver indexes and grey PVD-coated hands. The screw-down titanium case back and crown enhance water resistance to 300 meters, making it suitable for professional diving. A black technical fabric strap with a titanium buckle completes the look.
Price and Availability
With its advanced features and materials, the Ultra-Chron Carbon offers a blend of style, innovation, and reliability. Priced at approximately R92,000 (converted from USD 4,900), it caters to serious divers and collectors alike.
Final Thoughts
The Ultra-Chron Carbon represents a harmonious fusion of Longines’ heritage and modern ingenuity. It stands as a testament to the brand’s commitment to precision, innovation, and timeless design.
