The ActiVib bearing

Bearing with built-in vibrations damper 


The ActiVib bearing is a ball bearing that effectively filters the propagation of vibrations generated by the bearing to the other components of the movement.


To this end, the ActiVib bearing incorporates a vibrations damper made of elastomeric polymer especially developed for this purpose.



  • Filters the propagation of sound vibrations generated by the bearing.
  • Decrease in sound vibrations of around 10dBA.
  • Vibrations damper integrated into the bearing.

Actigir Principle

A technical innovation to reduce the noise of the rotor bearing 


The specific design developed for the cage constitutes the basis of the ActiGir principle. It allows a totally free rotation of the bearing in one direction and a controlled friction in the other one.


Advantages of the ActiGir principle in a rotor  bearing: 

  • Free rotation in one direction.
  • Controlled deceleration in the other direction.
  • Reduction of the noise level.

Assembly kit for flying carrousel and tourbillon

Thanks to this innovation, MPS Watch offers a solution that prevents any damage during the assembly and disassembly of the tourbillon cage components and thus removes any mechanical stress restricting its function.


Advantages of the Flyfix concept: 

  • The function is guaranteed by:
    • meticulous finish of the rolling areas
    • lubricant free thanks to ceramic balls
    • reduction of operational play
  • Assembly without the press-fit operation enables assembly and disassembly of the tourbillon cage parts with no risk of damage to the tourbillon cage components.
  • Fixing by means of a nut is controlled by using a torque wrench

Since 2005, MPS watch has been the key partner of major  manufacturers for the production of large diameter bearings.


The Titan bearing are used for a wide range of functions such as winding by peripheral oscillating weight, driving of indicator components or even as a base for the rotation of the movement around its axis.



Advantages of Titan bearings:

  • Automatic winding by peripheral oscillating 

    • The peripheral oscillating weight gives a 
full view of all the movement 
components through the transparent back

  • Driving indicator components
  • Base enabling the rotation of the movement 
around its axis
  • The integration of shock absorbers ensures:

    • greater shock resistance
    • a reduction in noise emission levels

MPS Watch miniaturises the unidirectional bearing concept and opens up new possibilities for designers of timekeeping devices.


Advantages of MPS' OneWay bearing:

  • Miniaturisation of the free wheel system
  • Space reserved for the self-winding 
system significantly reduced
  • Optimised cage segment design (brake pads) 
to ensure minimum backlash (dead angle)
  • The interfaces of various coupling components 
are calculated to allow the system to 
support significant loads
  • The operational clearance is totally controlled 
and tested to 100% to minimise axial play.
  • Lubrication-free system using myrox® 
ceramic balls developed by MPS
