We offer you a beautiful Longines Ultra-Chron on a cushion-shaped steel case,
featuring a very understated grey/purple dial, with applied onyx hour markers and our favorite Ultra-Chron logo at six o’clock, a representation of the wave with close peaks because the frequency is fast. On this model specifically, the frequency is 28,800 vibrations per hour.

As Longines celebrates its 190th anniversary in 2022, the brand has relaunched its Ultra-Chron. In 1959, Longines was ready to present the first high-frequency movement for a wristwatch: the caliber 360, oscillating at 36,000 vibrations per hour, manufactured by hand and adjusted for observatory competitions. The Longines Ultra-Chron was presented in 1967 to celebrate the centenary of Longines.
