JEWELING

  • All movements must be provided on the train and escapement with jewel bearings having polished holes. On the bridge side the jewels must be semi-brilliant with polished sinks. An endstone in the baseplate for the center-wheel is not required.

  • Movements with shock-absorbing devices are permitted.

  • For the rest of the movement and additional plates any jewel of good quality or other bearing is permitted.
