The ChronoMaster is a precision measuring device for meas-
uring the rate deviation, the amplitude and the beat error of
mechanical watches. The compact microphone has integrated
measurement electronics.
All common beat numbers can be determined automatically.
The manual adjustment for any beat numbers in a range
between 3’600 and 72’000 A/H is possible as an alternative.
Watches can be tested in the 6 main testing positions, in 4 ver-
tical intermediate positions and in 2 special positions. The
position is identified automatically.
Using different measuring modes, watches can be tested with
the following escapements:
•
Swiss anchor escapement
•
Cylinder escapement
•
Duplex escapement
•
Chronometer escapement
•
Co-Axial escapement
•
