A modular installation for assembly and repair that includes an adaptable number of assembly workstations, preferably at least one regulating station, a central oil station and a transport system for the transport of clockworks in disassembled or partially disassembled condition between the stations. By dividing the work steps into relatively simple assembly and the more demanding ones of oiling and regulating and by connecting the corresponding stations with a transport system as well as, at the assembly stations, a combination of two transport systems for controlled placement of the components of a particular clockwork movement and the associated transport components at an assembly station, a parallel but error-free and faster repair of clockworks is achieved. Preferably, the oil station is highly automated to carry out the oiling processes reproducibly and quickly. With the use of a manipulation ring, clockworks of different dimensions with standardized tools may be handled.

An escape wheel serving as a mechanical component includes an axle member, and an escape gear portion serving as a rotation member which has a holding portion for holding the axle member, and a rim portion having a plurality of tooth portions. The holding portion has a plurality of projection portions formed to project into a through-hole into which the axle member is inserted. An elastic portion extending from between the projection portions adjacent to each other is provided between the holding portion and the rim portion.
