Launched in 1967, the Ultra-Chron line represents one of the most important chapters in Longines' history, reaffirming its pioneering role in the development of high-frequency mechanical movements designed to achieve superior levels of precision.

This beautiful example features an elegant Jumbo stainless steel case, measuring approximately 37mm, and a sophisticated silver dial with a brushed finish, applied indices, and a crosshair configuration, characterized by the delicate lines that intersect at the center. The applied Ultra-Chron logo, signed crown, and distinctive steel bracelet with Longines clasp complement its classic aesthetic.

The star of the show is the Longines 431 in-house caliber, a 17-jewel automatic movement that operates at an impressive 36,000 vibrations per hour (Hi-Beat), equivalent to ten beats per second. An extraordinary technical achievement for its time, it consolidated Longines' position among the leading names in precision watchmaking.

With excellent visual presentation, elegant proportions, and a mechanically significant piece of horological history, this Ultra-Chron brings together the attributes most prized by vintage watch enthusiasts.

An opportunity to acquire a true icon of Swiss watchmaking engineering, combining history, sophistication, and exclusivity.
