LONGINES

Descrizione

In 1968, LONGINES launched the Ultra-Chron Diver, the first diver's watch equipped with a high-frequency movement. At the time, LONGINES had already established itself as a pioneer in high-frequency technology. As early as 1914, the winged hourglass brand created the first high-frequency timing device capable of measuring 1/10th of a second. In 1959, LONGINES developed the first high-frequency movement for wristwatches, an observatory chronometer that set new records in terms of precision. The new Ultra-Chron is inspired by the aesthetic codes and professional diving features of the 1968 model. These chronometer-certified watches are powered by an exclusive LONGINES calibre equipped with a silicon balance spring and resistant to magnetic fields. Self-winding mechanical movement with a frequency of 36'000 vibrations per hour and a power reserve of approximately 52 hours, monocrystalline silicon balance-spring. Screw-locked crown, Water-resistant to 30 bar, Scratch-resistant sapphire crystal with multi-layered anti-reflective coating on both sides. Anthracite dial, Swiss Super-LumiNova®. Bracelet Synthetic strap, With titanium buckle.
