Abstract
This disclosure depicts an electronic timepiece having complementary electro-optical and electro-mechanical displays. The electro-mechanical time display comprises a stepping motor driving hour and minute hands to continuously display the hours and minutes of the day, the most used time functions. The electro-optical display is a normally off two-digit LED display which is activated by user command to display at least one additional time-related function having a lower normal use factor than hours or minutes. The complementary electro-optical and electro-mechanical time displays are controlled from a common control means.
