Official description

The ULTRA-CHRON collection adopts carbon: an innovative material that is both strong and light, and now being used for the first time in a Longines watch case. Powered by a Longines’ exclusive high-frequency movement, beating at 36,000 vibrations per hour, this model draws inspiration from an iconic 1968 watch with a distinctive cushion-shaped case. Combining innovation and precision, each ULTRA-CHRON CARBON offers a unique design and is fully chronometer-certified by TIMELAB.

Beneath a sapphire crystal with a multi-layer, anti- reflective treatment, the sand-blasted anthracite dial features a chapter ring marked by twelve applied silver indexes. These, like the grey PVD hour and minute hands, are coated with a Super-LumiNova® blue luminescence treatment.

The ULTRA-CHRON CARBON is fitted with a black technical fabric strap featuring a titanium pin buckle. This watch is presented in a bespoke black box.
