LONGINES ULTRA CHRON DIVER Super Observatory Series L2.937.4.72.2 Classic Reproduction and Precise Innovation
In 1968, Longines launched the Ultra Cron Diver watch, creating a milestone in the industry - the first diving watch to feature a high-frequency movement, continuing the brand s pioneering position in the field of high-frequency technology. As early as 1910, the Longines watch, marked by the flying hourglass, created the first high-frequency timing device that could accurately measure up to 1/10 of a second; In 1959, the brand developed its first high-frequency movement for wristwatches, which was certified by the observatory and pushed the precision of wristwatches to a new level.
The all-new Longines ULTRA CHRON DIVER Super Observatory series L2.937.4.72.2 pays perfect tribute to the classic watch of 1968, not only restoring the classic aesthetics of that year, but also upgrading professional diving performance and internal precision. As an observatory certified watch, it is equipped with Longines exclusive movement and silicon balance spring, which can effectively resist magnetic field interference, ensuring long-term stability and accuracy. It is a perfect fusion of retro design and modern technology.
The watch details showcase craftsmanship: the case is made of stainless steel material, combined with sanding and polishing processes, with a delicate texture and durability; The crown is made of stainless steel, seamlessly integrated with the case, providing smooth operation and waterproof performance; The bezel is designed with stainless steel sanding, with clear markings, making it easy to quickly read the time while diving.
The dial features a silver sun pattern design, presenting a delicate luster under light and exuding a strong sense of luxury; The three-dimensional hour markers are polished and coated with a luminous layer, and the pointers are also polished and equipped with luminous function, allowing for clear reading of the time day and night; The central large second hand design ensures smooth and eye-catching timekeeping, with a date display window at the 3 o clock position, providing ample practicality.
The internal configuration is equally outstanding, equipped with the Longines L836 movement, with a vibration frequency of up to 5Hz (36000 times/hour), 25 gems, and a power reserve of up to 52 hours (2 days). It does not require frequent winding, making daily wear more convenient, perfectly balancing precision and practicality, and combining diving functionality with fashionable daily wear.
