Vintage LED AND LCD - Shacking Up For a Few Years

Bridging the gap between battery draining LED (light emitting diodes) and the more economical LCD (liquid crystal displays) was a brief period (1974-76ish) when both displays were used in one watch. Their purpose was primarily for displaying the time both day and night as internal lamp functions were not fully developed. Very few brands used this configuration but featured here are most of them...
