WITSCHI CHRONOMASTER AUTO PRO - HT67-AUTO-PRO

Witschi ChronoMaster® Auto Pro, the automatic microphone with infinite possibilities

Measures the beat noise of mechanical watches. It moves to all main test positions and any intermediate positions automatically and precisely. The movement in two axes is smooth and silent. It can measure while in motion and thus reveals new dimensions in the measurement of mechanical watches.

Compact and innovative drive solution with high-quality drive unit was developed to fit the needs of the ChronoMaster Auto Pro.

The motors are stowed in the foot section of the device to prevent magnetic fields from affecting the function of the movement. The compact design with a low centre of gravity occupies little space and provides a high degree of stability.

USB and Bluetooth interfaces

The ChronoMaster® Auto Pro requires a single USB cable for data connection and power supply for operation with a PC or the Witschi terminal. Alternatively, the measurement data can also be transmitted wirelessly via Bluetooth.
