  • the rods and pivots of the axle constituting zones of lesser mechanical resistance are provided to take up the forces involved. against their respective bearing due to their small dimensions, in particular their small diameter.
  • the watch axes are traditionally turned in 20AP steel, then hardened.
  • the pivots are then rolled to obtain the required surface condition and surface hardness.
  • the hardness typically reaches at least 700HV.
