As early as the 1910s, Longines developed a 5Hz high-frequency movement. After a series of innovations, Longines launched its first high-frequency wristwatch, the Ultra-Chron, in 1967, achieving mass production for the first time. In 1968, Longines followed up with its first high-frequency diver's watch, the Ultra-Chron Diver. The best Breitling Avenger replica watches at captainthewatch.is.
The Longines Heritage Classic Ultra-Chron Carbon watch is based on this historical model. In general, this watch has two main highlights: firstly, it features a high-frequency movement; secondly, it is Longines' first carbon fiber watch. Looking at the appearance, the carbon fiber case has a textured surface, a cushion-shaped design, a diameter of 43mm, and a water resistance of 300 meters. The black dial uses a three-hand layout, with Super-LumiNova® blue luminescent coating on the hour markers and hands for clear time reading in low-light conditions. A lightning bolt symbol (also found on the case back) is located at 6 o'clock, signifying the high frequency. The watch is powered by the Longines exclusive L.836.6 high-frequency movement, which vibrates at 5 Hz, features a silicon hairspring, and offers a power reserve of approximately 52 hours.
