The rebirth of a high-frequency icon: The LONGINES ULTRA-CHRON

The new LONGINES ULTRA-CHRON profits from Longines' rich heritage of producing high-beat movements for over 100 years. Inspired by the original Longines Ultra-Chron Diver of 1968, the new model reflects the iconic design codes of its ancestor. 

In 1968, Longines launched the Ultra-Chron Diver, the first dive watch to be equipped with a high-frequency movement. At the time, Longines had already established itself as a pioneer in high-frequency technology. In fact, the winged houglass brand created its first high-frequency timekeeping device to measure precisely 1/10th of a second as early as in 1914. In 1959, Longines developed the first high-beat movement for a wristwatch, an observatory chronometer that set new records in terms of accuracy. 

The new Longines Ultra-Chron features a unidirectional bezel as well as a screwed-in caseback and crown. It also offers great legibility and is water resistant to 30 bar (300 metres). 

The Longines Ultra-Chron's instantly recognizable 43.00mm cushion-shaped case is fitted with a diving bezel that showcases a sapphire insert with luminescent accents. The striking black grained dial features a white minute track with alternating Super-LumiNova®-coated batons and rhodium plated appliques. 

The original Ultra-Chron logo is proudly applied on the dial and embossed on the caseback. The new Longines Ultra-Chron has a distinctive red minute hand which, like the hour hand, is coated with Super-LumiNova® for optimal legibility. 

At the heart of the Ultra-Chron is the calibre L836.6, a high-frequency "in-house" movement. A watch can only be referred to as "high-frequency" when it is fitted with a movement with a balance-spring that oscillates at 36, 000 beats per hour (10 beats every second).

The accuracy of the Longines Ultra-Chron is confirmed by the chronometer certification issued by TIMELAB, and independent testing laboratory located in Geneva. This certification refers to the precision of the watch head.  

The Longines Ultra-Chron is available with a choice of a leather strap or a steel bracelet and it is delivered in a special presentation box containing a black NATO strap crafted from recycled material.
