ESCAPEMENT-MAKING (FINISHING)

Escapement-making (finishing) encompasses all the operations involved in regulating the escapement. Good escapement-making is essential for the proper running of the watch and its chronometry. The interactions between the various components of a pallets (lever) lever must be meticulously regulated in a very precise order.
In the case of watches with Swiss lever escapement, it is composed of the escape wheel, the Pallets (lever) and the double roller, although the latter is attached to the Balance staff and therefore to the regulating organ.
The Division between each component, the height or functional clearances must all be carefully adjusted by correcting numerous parameters (vertical positions of the components, positions of the pallet stones in their fork, positions of the banking pins, length of the Dart (safety pin), etc.).
Historically, during the era of the établisseurs (until the end of the 19th century) and more sporadically until the quartz crisis, the work was then sequenced and distributed to specialized workers working from home. Escapement-making (finishing) specialists were then logically referred to as “finishers”.
