30 Apr 1975TL;DR: A fully electronic chronometer using a quartz crystal as a frequency standard and displaying mean time by the use of electronically operated digital read-outs is described in this paper, where the circuit permits the display of the instant of time at which a switch is operated, while mean time continues to be counted by the circuitry.
Abstract: A fully electronic chronometer using a quartz crystal as a frequency standard and displaying mean time by the use of electronically operated digital read-outs. The circuit permits the display of the instant of time at which a switch is operated, while mean time continues to be counted by the circuitry. Other features include conservation of power by display of mean time only upon demand and the provision for control and display remote from the timing circuitry.
