Description
In 1968, LONGINES introduced the Ultra-Chron Diver, marking the debut of the first dive watch with a high-frequency movement. LONGINES had long been at the forefront of precision timekeeping, having crafted the first high-frequency device capable of measuring 1/10th of a second in 1910. By 1959, the brand developed a groundbreaking high-beat wristwatch movement, earning observatory chronometer accolades for its exceptional accuracy. This new Ultra-Chron pays homage to the design and professional diving capabilities of the original, featuring chronometer-certified movements with an exclusive LONGINES calibre, silicon balance-spring, and magnetic resistance.
