Controlling device (Assortiment)

Balance staff

As carrier of balance rim, roller and mainspring, the balance staff is the central element of the controlling device in the mechanical clockwork. In order to achieve a high clock accuracy, friction must be minimized... more

Escape wheel pinion

As carrier of the escape wheel, the escape wheel pinion (pignon d‘échappement) is a component part of the escapement consisting of the escape wheel and the pallet fork. In a mechanical clockwork, it's the escapement's task to uniformly distribute the energy coming from the mainspring (barillet) to the balance (regulating device)... more

Pallet staff

As carrier of the pallet fork, the pallet staff (tige d'ancre) is a component part of the escapement in the mechanical clockwork consisting of the escape wheel and the pallet fork. It's the escapement's task to uniformly distribute the energy coming from the mainspring (barillet) to the balance (regulating device)... more

Large roller with impulse pin (roller mounted with roller jewel)

The large roller with impulse pin mounted on the balance staff or on the balance rim and the mainspring is the central element of the regulating device in the mechanical clockwork. In order to achieve a high clock accuracy, the large roller with impulse pin must be manufactured with a very high degree of symmetry... more

Balance / Oscillator (Balancier réglé / Oscillateur)

Balance together with balance-spring, which is supplied with energy through the gear train, produce the oscillations regulating the movements of the gear train of the mechanical watch. The balance is a component part of the controlling device (assortment) which consists of the escapement which itself consists of the escape wheel and the pallet fork (mobile d’échappement, ancre)... more

Escape wheel

The escape wheel pinion (mobile d'échappement) is a component part of the gear train which ensures energy transmission in the mechanical clockwork between barrel (barillet) and balance. The gear train ensuring energy transmission between barrel and balance consists of the third wheel... more

Pallet fork (Ancre montée)

The pallet fork (pallet fork, entry pallet, exit pallet, palett staff and guard pin) is a component part of the escapement and follows after the gear train. It's the main function of the pallet fork to uniformly distribute the energy coming from the mainspring to the balance (regulating device)... more

Spiral

The spiral spring and the balance wheel are provided with energy by the gear train. As a result, the spiral spring produces oscillations, which are regulating the expiration of the gear train of the mechanical movement… more

Dard

The dard is a very important part of the anchor. It is regulating the energy, which is produced by the mainspring. The dard distributes this energy evenly to the balance… more
