オメガ
The Omega Chrono-Quartz was the world’s first digital/ analogue chronograph. It was invented by Omega SA. The watch launched at the 1976 Montreal Olympic Games and was Omega's flagship chronograph at that time. The watch is noteworthy as it was the first chronograph wristwatch in the world to combine analogue display for the time functions and a digital display for the chronograph function, each working independently of one another but running on the same quartz resonator.
