Abstract

A digital wristwatch with dual displays, one a liquid crystal display (LCD) for use in daylight or bright light and the other a light emitting diode (LED) display for use in dim light, is provided with three controlling push buttons (LED, Date and Set) for five display conditions and four setting conditions. With no button pressed, hours and minutes are displayed by the LCD elements. The LED button alone causes the LED elements to also display the hours and minutes for at least 1.5 seconds and the Date button alone causes the date to appear by the LCD, and if the Date push button is held over about 1.5 seconds the date will also appear on the LED display. The LED and Date buttons pressed together will cause the LCD elements to display the seconds, even after they have been released for "hands off" seconds display until either push button is again momentarily pressed. The Set button slews hours when pressed alone, and slews minutes and instantaneously zeros seconds when pressed together with LED, and slews the date when pressed together with the Date push button. Pressing all three will cause a complete reset of all counters.
