Essay: The OMEGA Chrono-Quartz was invented by OMEGA and launched at the 1976 Montreal Olympic Games. It was the world’s first digital/analogue chronograph and OMEGA's flagship chronograph at that time.
The Chrono-Quartz was the first chronograph wristwatch in the world to combine analogue display for the time functions and a LCD digital display for the chronograph function, each working independently of one another but running on the same quartz resonator (32 kHz).
