1988 - Junghans Solar 1

Junghans made the Solar 1 watch for a number of years in a variety of cases. This is model 2471000401. There is a black bar across the center of the watch with the inscription, “Junghans, solar 1” and a white date window with an analog mechanical date. The date and time settings are conventionally stem controlled. The stem is located at the 3 o’clock position.

Comment: This watch design really takes advantage of the color of the amorphous silicon solar cell. The case and the hour marks on the face are spare, showing off the color of the solar cells which cover the solar cell almost the entire face in a deep, rich blue color.
