Bearing with integrated vibration damper


ActiVib & ActiVib evolution bearings

The ActiVib bearing effectively filters the propagation of vibrations generated by the bearing to other components of the watch. For this purpose, the ActiVib bearing incorporates a damper made from elastomeric polymer specially developed for this application.

Patent number: EP18176688

 

The ActiVib evolution bearing uses the same construction principles as the basic version. The only difference is that the polymer is not visible through the transparent caseback. As a result, the ActiVib evolution version is compatible with the aesthetic codes of Haute Horlogerie.
Tests performed in laboratory show a decrease in sound vibrations of around 5 dBA for ActiVib evolution.

Benefits

  • Filters the propagation of sound vibrations generated by the bearing
  • Reduces noise level by around 10 dBA
  • Vibration damper integrated into the bearing
  • ActiVib evolution hides the polymer

A team listening to your concerns

The type and level of sounds generated by rotation of the rotor can disturb a sensitive wearer of a mechanical watch with automatically-wound movement. To limit such effects, our engineers have created a bearing with built-in damper: the ActiVib bearing. It incorporates a damper made from elastomeric polymer specially developed for this application.
