Orient Watch Company worked with the Sharp Corporation of Japan to develop this LCD watch, the only solar watch that Orient has made.
The multiple features include month, day, date, lap times and a light.
The watch has crystal solar cells that supplement the power of a standard button battery (393 or SR754W).
The inscription on the back reads:
ALL STAINLESS STEEL
The Orient Watch Company estimates the date of the watch as 1979 or 1980.
