Longines Watches

Ultra-Chron

The Longines Ultra-Chron is a modern reinterpretation of a historic model from 1968 that was particularly renowned for its high accuracy. With a frequency of 36,000 vibrations per hour (5 Hz), it sets new standards in the precision of mechanical timepieces. This high frequency enables more accurate timekeeping and improved shock resistance.

About the Ultra-Chron Collection

The black dial with bright line indices instead of numerals ensures optimum readability thanks to the contrast. The scratch-resistant sapphire crystal adds to the robustness. A stainless steel bracelet with a folding clasp rounds off the sporty, elegant appearance. The 43 mm case is also made of stainless steel and is water-resistant to 300 meters, making the watch attractive for professional divers. 

In addition, the automatic caliber L836, which was specially developed for high-frequency operation, ensures reliable functionality in the Ultra-Chron. This movement not only offers impressive precision, but also a power reserve of approximately 52 hours. 

With its understated appearance, black dial, and stainless steel bracelet, the Longines Ultra-Chron combines the aesthetics of the late 1960s with state-of-the-art watchmaking and is aimed at lovers of precise, mechanical timepieces with historical flair.
