    摘要: A stop watch comprising a second hand and a subsecond hand includes manually actuatable switches for producing start, stop and reset instruction signals. A first stepping motor and a first drive controller for the stepping motor drives the second hand, while a second stepping motor and a second drive controller drives the subsecond hand. The second drive controller includes a counter for counting subsecond clock pulses in response to the start signal for effecting the display of the contents of the counter by the subsecond hand in response to the stop signal.

    摘要: A measuring device electronics comprises a processor and two clock signal generators. One clock signal generator serves for producing a working clock signal, and also for producing a reference clock signal which is dependant on the working clock signal. The other clock signal generator, serves for producing a second reference clock signal, which is independent of the working clock signal. Based on the two independent reference clock signals, a frequency difference, can, to the extent that such is present, be ascertained during operation of the measuring device electronics or of the measuring device formed therewith. The frequency difference, represents a difference between the instantaneous clocking frequency of the first reference clock signal and the instantaneous clocking frequency of the second reference clock signal, and, in this respect, represents a measure for a deviation of an instantaneous clocking frequency, from the nominally predetermined clocking frequency, of the working clock signal.

    摘要: Movement for chronograph watch comprising: a barrel (1); a main gear train (RH) for driving one or more current time indicators (43); a regulator member comprising a generator (8) driven by the main gear train (RH), the generator powering an electronic regulation circuit (80) to control the speed of rotation of the main gear train as a function of a quartz oscillator (81); a chronograph gear train (Rc) that can be brought into mesh with the main gear train (RH) to drive a timer indicator (152). The chronograph gear train can be brought into mesh with a wheel (8) that performs more than one revolution per minute.
