Longines: Ultra-Chron
30 June 2022Inspired by the aesthetic codes and professional diving characteristics of the 1968 Longines Ultra-Chron Diver, the winged hourglass brand unveils the new Ultra-Chron with high frequency movement.
Faithful to its predecessor, the first diving watch equipped with a high-frequency movement, the new model is equipped with a unidirectional rotating bezel as well as a screwed-in caseback and crown. It also offers great legibility and is water resistant to 300 meters.
The Longines Ultra-Chron’s instantly recognizable 43mm cushion-shaped steel case is fitted with a diving bezel that boasts a sapphire insert with luminescent accents. The eye-catching 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 new Ultra-Chron is the automatic caliber L836.6, a high-frequency “in-house” movement with silicon balance-spring and 52 hours of power reserve. The accurancy of the Longines Ultra-Chron is confirmed by the chronometer certification issued by TIMELAB, an independent testing laboratory located in Geneva. This certification refers to the precision of the watch head. The qualification process subjects the finished product to a 15-day testing period during which the watch is subjected to a series of tests at three temperatures, 8 °C, 23 °C and 38 °C, confirming that it meets the strict precision criteria.
The new Longines Ultra-Chron is available with a choice of a leather strap (€ 3,630) or a steel bracelet (€ 3,840) and it is delivered in a special presentation box containing a black NATO strap crafted from recycled material.
