The Longines Ultra-Chron represents an important milestone in the history of watchmaking, marking Longines' continued commitment to technical innovation and precision. Launched in 1967, to mark the brand's centenary, this watch is distinguished by its high-frequency movement, an advanced technical feature that aimed to provide unrivaled precision at the time. At the heart of the Ultra-Chron lies a revolutionary movement, the chronometer-certified Longines caliber 431, operating at 36,000 vibrations per hour.
The aesthetic of the Ultra-Chron, ref.7821-1 remains faithful to Longines' spirit, combining classic elegance and optimal readability. The 35mm, 18k yellow gold case is unique, with the lugs featuring sharp chamfered corners, reflecting a style that is both sporty and refined. The brown dial is very readable, with hour markers and hands reflecting the facets seen on the case.
Our "Brownie" Longines Ultra-Chron comes from 1968 with its box, its gold plated Longines buckle and our chocolate pigskin premium strap.
