Longines ULTRA-CHRON CARBON

A FIRST FOR LONGINES

The Ultra-Chron Diver, first introduced in 1968 as the first high-frequency diver’s watch, returns in a cutting-edge new model. Longines, a pioneer in high-frequency movements since 1910, unveiled this latest version with a carbon case—its first use of the ultra-light yet durable material. Inspired by aeronautics, the 43mm case is crafted from unidirectional carbon fiber and epoxy resin, creating a unique pattern on each timepiece. Weighing under 80 grams, it is water-resistant up to 300 meters. The watch features a fixed titanium bezel with an engraved aluminium insert, a titanium case back and crown, and a sand-blasted anthracite dial under a sapphire crystal. Super-LumiNova® blue luminescence enhances the silver indexes and grey PVD-coated hands, ensuring visibility in all conditions.

HIGH FREQUENCY AND PRECISION

The Ultra-Chron Carbon is powered by Longines' high-frequency calibre L.836.6, oscillating at 5 Hz for enhanced stability and shock resistance. With a silicon balance-spring, it is ten times more resistant to magnetic fields than ISO 764 standards. Certified as a chronometer by TIMELAB, it undergoes rigorous 15-day testing for accuracy. The watch comes with a black technical fabric strap, a titanium buckle, and a bespoke black box.
