Combined Instrument for Quartz and Mechanical
Watches
This combined measurement and test instrument associates
all functions of test equipments for quartz watches and test
equipments for mechanical watches. It is the ideal test instrument
for the repair service, the lab and watch sales outlets.
Basic functions and measurement sequences, largely automated,
provide a fast and efficient operation.
Additional measurement modes provide a way to measure
watches with special escapements. The instrument, based on
the “all-in-one” concept, only requires a very small work area.
With its hi-res colour display, this top class instrument certainly
draws attention, also in the sales room.


General Description

A new technology provides extended test and measurement
facilities, allowing fast and professional troubleshooting
of quartz and mechanical watches.
Largely automated measurement sequences provided by
the instrument result in an unmatched user-friendliness. For
more advanced users, measurement parameters can also be
manually selected according to requirements. The main menu,
results, parameters, submenus and information are
presented on a colour display.


Testing Quartz Watches

Rate Measurement and Pulse Parameters
The analysis of the magnetic signal provides a display of the
accuracy. It also allows checking the period duration, the
pulse width as well as the inhibition period and the drive
level. Based on this information, it is possible to determine
the efficiency of a watch drive without opening the watch.

Rate and Consumption Measurement
The watch to be tested is supplied with a variable voltage.
Moveable probes are used as contact elements. The hands
can be observed during measurement by means of the
built-in mirror.
The instantaneous values of the rate deviation and of the
total consumption are displayed on a logarithmic scale. The
IC current, the period duration, the pulse width, the inhibition
period and the drive level are numerically displayed.

Pulse Analysis of the Motor Current
The current pulses are shown as a curve. The pulse shape is
an important criterion about the good operation of the
watch. Faults can be detected in the mechanical part of the
watch by comparing its measurements to those of a watch
of the same type in good condition. In addition, the pulse
width and the drive level are displayed numerically.


Testing Mechanical Watches

Diagram Display Mode
The diagram is continuously drawn. The numerical rate,
amplitude and beat measurements are displayed at the end
of the first measuring time. The average of the single measurements
is updated every 2 seconds, even with a longer
set measuring time.

Vario Display Mode
This mode provides a clear-cut assessment of the rate and
amplitude stability. The results are displayed in graphical
form on a logarithmic scale. The min., average and max.
values of single measurements since the beginning of the
measurement process are displayed under the current results.
The beat number as well as the measuring time since
the beginning of the measurement process are also displayed.

Trace Display Mode
In this mode, the measurement result of rate and amplitude
are recorded graphically in a time range depending on the
measuring time. It can be selected from 8 minutes to max.
64 hours. This provides a way to detect and locate recurring
deviations (e.g. faults in the gear train).

Position Display Mode
This mode provides measurement cycles with 2 to 6 test
positions by manually rotating the microphone. The instantaneous
measurements of rate, beat and amplitude are
collected during the measurement process. The average of
the rate and amplitude for each test position is displayed at
the end of the measurement cycle. The measured values of
the amplitudes are also represented by a light blue bar.
