GENERAL INFORMATION
WATCH SCOPE,
EXPERIENCE YOUR WATCH
Watch Scope is a instrument that enables you to make a full check up of
your mechanical watches, made up of an Android or iOS application and a
watch stand with an integrated electronic measuring system.
PACKAGE CONTENTS
- One watch stand
- One connecting cable
- One user guide with the activation code
Watch Scope allows you to measure several of your watch’s key elements:
Frequency : The number of vibrations produced by the watch’s
balance per hour. The higher the frequency, the more precise the
balance. The vibrations made by the balance produce a watch’s tic-
king. Frequency is measured in a/h (alternance per hour).
Rate variation : The rate performance indicates the deviation of
your movement, running either too fast or slow, in seconds per day.
For the record, a chronometer certified by the COSC should have
an average rate of between -4 and +6 seconds per day. The rate is
measured in s/d (seconds per day).
Beat error: Indication of an asymmetrical oscillation of the balance
wheel. A “perfect” movement should have a beat error of 0ms, and
if it doesn’t, the balance wheel is oscillating further in one direction
than in the other. The beat error is measured in ms (milliseconds).
Amplitude (of the balance spring): The amplitude values of today’s
watches are around 270° - 310°. With age, the lubricants break
down and this value progressively decreases over time. The ampli-
tude is measured in ° (degrees).
Lift angle: When listening to the sound produced by a watch, we
only hear its ticking. However, the sound of a watch’s beat is more
complex and each “tick” is made up of three different pulses.The
angle that the balance wheel travelled between the first and third
noise is called the “lift angle”. The lift angle is a geometric feature of
a movement and is used to calculate the balance wheel’s amplitude.
If you don’t know the lift angle of your movement, you can find it
thanks to the link below:

QUICK MEASUREMENT
STARTING A MEASUREMENT : Click
Start
and let the application do the
rest.
STOPPING A MEASUREMENT :
In the normal mode, the measurement
will stop automatically. In the continual analysis mode, you need to click
Stop
.
Lift angle :
The lift angle is a characteristic of a watch’s calibre. This angle
is used to calculate the amplitude. For most calibre this angle is around
50° and is provided by the watch manufacturer. To precisely measure the
amplitude, enter the lift angle of the calibre being measured.

Bring together all the important
information necessary to check the
accuracy of your watch:
Frequency (a/h)
Rate variation (s/d)
Beat error (ms)
Amplitude (degrees)

3 - D
Select the desired mea-
surement time:
10s, 30s, 45s, 60s, 120s.
The higher the duration, the
more precise the measurement.

COLLECTION
Using this mode, you have the possibility of measuring your whole collec-
tion and obtaining a complete history of measurements for each watch.
The purpose of this function is to detect if a malfunction occurs over time.
To add a new watch, select + at the top right of the screen.
CHART
In the
continual analysis
mode, a chart
will appear that allows you to determine
the rate performance of your watch in
real time.
Normal curve : Average rate perfor-
mance of the watch.
Dotted curve : Current rate of the last
10s, 30s, 45s, 60s and so on, according
to the selected duration.

To obtain a precise measurement, calibrating
your Watch Scope is IMPERATIVE. Connect
to the internet, start the calibration and wait
30 minutes or 3 hours (select your calibration
mode). You only need to do this for first time
use or if you ever reinstall the system.
CALIBRATION
Watch Analyzer is connected to atomic clocks in order to test and calibrate
its time base. This way, the Watch Analyzer guarantees exceptional mea-
surement quality up to the highest standards of professional horologists.
To do this, simply connect your mobile device to the internet and begin
the calibration by clicking
Start
