The Most Recent Technology for Testing Mechanical
Watches
The Chronoscope X1 is the top-of-the-line instrument to be
used during manufacturing, by the repair service or in the
watch-testing lab. It includes the X1 terminal with a 10.4”
colour touch screen and the automatic Micromat C microphone
with integrated Chronoscope measurement electronics.
It provides 4 different display modes as well as a
graphical representation of beat noises.
PDF files can be individually stored with each measurement
program. They can contain e.g. mounting drawings, limit
data, lubricating schedules, etc. and can be called back
whenever necessary.
The large touch screen provides an extremely

General Description
The X1 terminal is used as the control and display unit. Its
large screen provides three content-ordered menu bars
with big, self-explanatory buttons around the main display.
The 4 display modes show measurements in a way adapted
to any individual requirements. The measurement results
can be printed on an external printer without interrupting
the ongoing measurement process. It is possible to create
up to 99 different measurement programs. The automated
microphone Micromat C can be operated directly from the
terminal or with its own function keys.

Particular Features
–– Display of PDF documents
PDF documents, e.g. mounting drawings, maintenance
recommendations, reference data, etc. can be individually
assigned to each of the 99 measurement programs.
For opening the PDF document, it is enough to key in
the program number (paperless office).
–– Screen capture (camera function)
The current content of the screen is stored in JPG format
into a plugged-in USB memory stick when the camera
key is pressed.
–– Picture presentation
Up to 99 pictures in JPG format can be stored for the
start/stop screen saver. The slide show runs at a rate of
a new picture every 10 seconds.
Continuous Diagram Recording
The rate deviation is continuously drawn on the screen.
Measured values for rate deviation, amplitude and beat error
are displayed numerically.

New
In addition to the diagram recorded in the main window,
the last eight diagram pages are shown as small format
strip.

Trace Display Mode
In this mode, the rate deviation and the amplitude are recorded
in parallel in graphical format. The Trace mode provides
long-term measurements up to 100 hours. This provides
an extended time range (e.g. power reserve cycle) for
measuring movements.
In addition to the graphics, the current test position of the
watch as well as the running measured values for rate deviation,
amplitude and beat error are also displayed.

Handy Feature
It is possible to switch between the Trace and Vario modes
while the measurement process is running.

Vario Display Mode
The Vario mode measures the rate and amplitude stability
over a longer time range. Each numerical measurement is
represented by an arrow on the linear scale.
The following values are constantly updated as long as the
measurement process is running:
–– smallest measured value
–– largest measured value
–– average measured value and standard deviation
–– elapsed measuring time.

Sequence Display Mode
This neatly structured table clearly displays the measurement
results in each position as well as the average and the
largest difference between all positions and particular
ones.
Programs can be created with up to 6 test position including
stabilisation and measurement time. The sequence can
also be initiated with the start key of the Micromat.

Handy Feature
The arrow keys can be used for toggling between the
Trace, Vario, Sequence and Diagram Recording measurement
modes during or after measurement.

Scope Display Mode
The Scope function graphically displays the acoustic beat
noise of the watch. A detailed analysis of the beat noise,
i.e. of the state of the escapement, can be carried out.
Signal levels are represented as an envelope curve. The
measured value of the amplitude is numerically displayed.
The display is based on one of the following three time intervals:
20 ms, 200 ms and 400 ms.

New
The last eight beat noises are displayed in a small format
and continuously updated when the measurement process
is running.

Time and Date
This neatly structured display is ideal for setting up the date
and time after a test.
In this mode, the time and date are displayed in analogue
and digital form. A signal sound repeated every 15 seconds
can be optionally switched on. A top-of-the-minute signal
is generated whenever the last 5 seconds of the minute are
reached.
If the instrument is connected to a network, the watch can
be synchronised up to the second over the Internet by a
time server (NTP).

Measurement Possibilities
Rate deviation, amplitude and beat error of mechanical
watches. Diagram of the beat noises.
Beat Number
Automatic selection of all common beat numbers.
Manual selection of any beat number between 3’600
to 43’200 b/ h.

Measuring Modes
–– Standard mode for watches with the Swiss
escapement.
–– Special1 Mode for watches with coaxial escapement.
–– Special2 Mode for watches with AP escapement.
–– Special4 Mode with specific amplitude filter for the
measurement of watches with the Swiss escapement.
Gain Control
Automatic. Manual control facility for watches with stray or
unusual beat noises.
