ABSTRACT:
A selective switching mechanism for an electronic watch having a four digit electro-optic display, the mechanism having three operative positions. In the first switching position, the display is that of hours and minutes and requires for its full scale all four digits. In the second position, the display is that of seconds and requires for its full scale two of the four digits, and in the third position the display is calendar date and requires for its full scale two of the four digits. The switching mechanism is operated by a crown and stem assembly which occupies the first position when depressed part way, and which occupies the second position when fully depressed. The third position is occupied by pulling out the crown. Thus all three switching positions are attained by operation of a single actuating element.
