27.02.2018Precision measuring device Watch ...6

The Watch Expert is a precision measuring device for determining
the accuracy of mechanical watches.
The choice of parameters can be adjusted to suit the given require-
ments.
The Watch Expert automatically calculates measured values for
rate deviation, amplitude and beat errors, and displays them
numerically.
With the aid of 4 different test modes, mechanical watches with the
following escapement types can be measured:
nAnchor escapement
nDuplex escapement
nCylinder escapement
nChronometer escapement
nCo-axial escapement
nAP escapement
in addition to watches with unusual beat noise.
The typical beat numbers of all common watches are recognised
automatically by the Watch Expert. Alternatively, the beat number
can be entered manually.
In addition to the “Diagram display mode” , which shows the meas-
urement in the form of a diagram, the Watch Expert also features
the “VARIO display mode” , which shows rate accuracy and ampli-
tude measurements and displays the smallest, largest and
resulting mean values, in each case.
With the aid of the pivoting microphone, a watch can be measured
in 12 different test position.
The switching screw on the rear side of the microphone ensures a
stable handling position for left and right-handed users.
Bluetooth functionality allows the device to be connected to a suit-
able printer so the measured results can be printed out. Bluetooth
functionality is possible using an optional dongle. Otherwise the
connection is via the serial interface.

The pivoting microphone (Fig. 3/1) provides 12 different test posi-
tions for measuring mechanical watches. The neoprene clamping
jaw (Fig. 3/2) can be adjusted in accordance with the size of the
watch. To ensure a stable hand resting position, the microphone
can be adjusted for left/right-hand users with the aid of the
switching screw (Fig. 3/3). The freely programmable keys (Fig. 3/4)
are used to navigate through the menu. Alternatively, the keys can
be assigned an individual function.

User interface
27.02.2018Precision measuring device Watch ...10

Touch button Function
Provides 3 different options for setting the beat number:
nAutomatic: The beat number is recognised automatically.
nManual: The beat number (value between 3,600 b/h and 86,400 b/h) can
be entered manually.
nFrequency: The beat number is calculated automatically to obtain a rate
deviation of 0 s/d.
Provides the option of entering the beat time (value between 3,600 b/h and
86,400 b/h) manually.
Provides the option of manually selecting/entering the lift angle (value between
10° and 90°).
Provides 4 different option for setting the test mode:
nStandard: Mode for watches with Swiss anchor escapement. To determine
the amplitude of the watch, the lift angle must be specified.
nRate: Mode for rate measurement of watches with cylinder, duplex or chro-
nometer escapement, in addition to watches with unusual beat noise.
nSpecial 1 (co-axial):: Mode for watches with co-axial escapement.
nSpecial 2 (AP): Mode for watches with AP escapement.
Display element Function
Shows the rate deviation in s/d.
Shows the amplitude in °.
Shows the beat error (repère) in ms. If the zero-crossing is reached
during calibration (fine-tuning) the Δ symbol appears in addition to the
beat error, e.g. Δ 0.9 ms.
Shows the currently-set test position of the watch. The flashing bars indi-
cate that measured results are being received.

Position window for the 6 main test positions. Shows, in diagram display
mode, which test position is currently being measured.
The following 12 test positions (designation of the main test position as
per NIHS 95-10/ISO 3158) are possible:
Selected parameters
The selected parameters are shown in green in the
main display and in the settings menu.
1.4 Modes
The Watch Expert provides 4 test modes that can be set in accord-
ance with the escapement type of the watch to be tested.

Modes
27.02.2018Precision measuring device Watch ...12

Test mode Additional information
Standard Mode for watches with Swiss anchor escapement.
To determine the amplitude of the watch, the lift
angle must be set.
Rate Mode for rate measurement of watches with cyl-
inder, duplex or chronometer escapement, in addi-
tion to watches with unusual beat noise.
Special 1 (co-axial) Mode for watches with co-axial escapement.
Special 2 (AP) Mode for watches with AP escapement.
Determining the escapement type
You can find out the escapement type of the watch
that is to be tested by consulting the watch manu-
facturer.
The Watch Expert provides two different display modes in which
various parameters are measured and displayed.
Appearance Function
Diagram nShows the rate deviation, the beat error and the
amplitude.
nDuring the measuring procedure, the measured
values are displayed as a diagram.
nIt is possible to configure the diagram view.
nThe 6 position windows show the diagram as it
relates to the respective measuring position.
nIf the measuring procedure has stopped, the meas-
ured values and the diagram can be shown in the
large display by tapping the small position windows.
VARIO Visualises the rate stability and amplitude over a longer
period.
During the measuring procedure, the current measured
values, including the mean, are shown over the entire
measuring period, in addition to the minimum and max-
imum rate and amplitude values.
