History Introduced in the late 1960s to celebrate the brand's centenary, the Longines Ultra-Chron line was designed around high-frequency automatic movements intended to provide superior accuracy. The collection represents an important era of mechanical innovation, created during a time when watchmakers were pushing the limits of beat rates to compete with early electronic timepieces. This 1972 example, powered by the caliber 6651, reflects that pursuit of precision while showcasing the distinctive cushion-case styling characteristic of the decade. / Second Vintage SKU: LON-AUX-0002
