This is truly a beautiful piece that any watch collector can appreciate. Story The Longines UltraChron is a watch that ticks all the boxes that we require of a proper vintage dress piece. Introduced in the late 1960s and produced for only six years, the UltraChron is an early attempt by the brand to mass-produce a mechanical watch that, according to their advertisements, was "the world's most accurate watch... guaranteed accurate to within one minute per month." This was achieved with the hi-beat Caliber movement, which had a beat rate of 36,000 beats per hour.
