Piece of a watch

Glass (watchmaking)

The watch glass also known as ice shows , is the transparent part which allows both to read the signs and protects its constituent parts. Not to be confused with watch glass : laboratory equipment . Materials Initially, made of glass and then of composite materials , either plastic , for example Plexiglass , or […]

Winding stem

The winding stem is a rod that connects the crown of a mechanical watch to the mechanism, called “movement”, in order to act on the latter. Function Its primary function is to allow the winding of the watch. Without it, the reassembly and the setting on time were done by key. Often threaded in modern […]

Système antichoc (horlogerie) — Wikipédia

The shock absorbing systems are used in the mechanical movements to protect the critical alignment of the axes of the rocker in the event of a shock. Description The anti-shock system protects the balance pins by means of very thin steel springs (mounted at the end of axes). Normally a timepiece (also called ” ruby […]

Clockwork (clockwork)

The clockwork is, in clockwork, a part of the movement of the watch. It consists of all gears and sprockets. Gear wheels The toothed wheels divide the time unit given by the regulator ( balance / spiral / anchor assembly ). Gear wheels The sprocket wheels give the indication of the time measurement corresponding to […]

Spiral spring

The spiral spring , with non-contiguous and therefore frictionless spirals, is composed of a ribbon of rectangular section embedded at one end B and secured at the other end O to an axis perpendicular to the winding plane. In this watch bracelet, the spiral has blue reflections. In watchmaking , the spiral spring is a […]

Engine spring

The motor spring or (in clockwork) spring barrel is a spring enabling to store energy when it is tensioned, and to restore it during the trigger. Most of the time it is a metal strip of hardened steel wound on a wheel. The energy returned is transmitted by a set of gears . In some […]


The winding mechanism is a mechanism used to arm the spring or to raise the weight of the time instruments. Winding and setting the clock: these two mechanisms are generally linked by common bodies.

A regulator is a skilled worker 1 or technician whose role is to regulate the machines of production. The settings of the machines include the parameters, the tools, the cadences, the laying of the molds 2 , etc. The controller is responsible for level 1 maintenance and preventive maintenance . In watchmaking A regulator, or […]

Platinum (watchmaking)

The plate is the base plate supporting all the components of the mechanical movement of a watch . It is part of the draft . Normally made of brass , it can also be manufactured from precious metal , or synthetic sapphire . Description The plate is provided Of the incrustations necessary for housing the […]

Perpetual Calendar

The perpetual calendar is a watch complication consisting of displaying on a mechanical watch the day of the month (the date ), the month and the position of the year in the cycle of the leap years automatically: the change from the last day of the month to 1 st of the following month does […]
