What makes this timepiece exceptional
Longines registered the Ultra-Chron trademark in Switzerland on October 28, 1966. The entire collection is defined by the high-frequency movement that powers it. In terms of serial production, it is one of the most precise watches of this era: Ultra-Chron, short for Ultra-Chronometer, implies that this movement can guarantee much higher standards of precision than traditional chronometers. The Longines Ultra-Chron was the last mechanical watch to match the precision of electronic watches of its time. And of course, no batteries are required. The watch is certified as a Chronometer by the COSC.
