A digital LED display watch is provided with 1) an operating button to select and control display of data in the normal operating mode, and 2) a recessed button to select separately for possible setting each unit of horological data except seconds. The display of the data selected for possible setting is flashed, and the actual advancing is controlled by the operating button. The data displayed in the normal mode is timed hours-minutes, separated by a colon, with seconds after hours-minutes if the operating button is held down, and month-date separated by a dash if the operating button is pushed twice. In the setting mode, data not being set (but otherwise associated in the display with data that is) is blanked, but the colon or dash is retained. During setting of hours the dash is added to the colon during the first 12 hours of each day to indicate AM. An optional recessed button is provided to manually select the duty cycle of the LED display and thus alter apparent brightness and power consumed.
