Abstract

1495901 Electronic chronographs HEUERLEDNIDAS SA 19 Jan 1976 [24 Jan 1975] 02021/76 Heading G3T An electronic chronograph 1 has a first display portion 2 using passive, e.g. liquid crystal, elements 3 to show the time of day, and a second display portion 4 using light emitting elements 5, e.g. LEDs, to show elapsed time. As described the time display 2 is illuminated by a bulb 6 when a button 7 is pressed; depression of a button 10 causes this display portion to show the date. The chronograph display is controlled by two further buttons 8, 9 the depression of either causing the diodes 5 to be energized; the display 4 can be held to display a lap time while counting continues.
