[ RIQUARTZ LED 910 ] RICOH JAPAN 1973

Luxury LED Watch is First Produced in Japan

This is Japan's first LED watch. It used an early module made by Hughes Aircraft and a high frequency 786,432 Hz quartz. Due to the slightly above-center position of the LEDs, the round red display is also offset upward, enabling the LED digits to appear in the center of the display and also giving it a unique design.
