From this date onwards, its certification will encompass the watch as a whole. Formally amended in November 2011, the new hallmark regulations came into force in June 2012. Techniques and materials evolve and, for its 125th anniversary, the “Poinçon de Genève” decided to keep up with this evolution by adapting its demands. These criteria involve the finishing of the parts (chamfered and hand-drawn bridges, polished sinks, chamfered going train) and their characteristics (type of balance wheel-spring pinning, type of index, thickness of the escape wheel), as well as the non-use of certain parts such as wire springs. A watch is thus only eligible if its movement is assembled and adjusted in Canton Geneva, if it is numbered and if it meets the craftsmanship criteria established by the Technical Committee. The “Poinçon de Genève” quality hallmark, created in 1886 in order to protect Genevan watchmaking, involves three fundamental conditions of admission and different qualifying criteria.

If the watch has stopped, wind it manually before wearing it by making around 50 clockwise turns of the crown.īe aware that some models have a screwed crown. A watch with an automatic self-winding movement is equipped with a sliding mainspring which is a mechanism placed in the barrel to avoid over-winding of the mainspring. When the mainspring is fully wound, it has a minimum power reserve of 40 hours and a maximum of 9 days depending on the model. The motion of your wrist makes a rotor turn, which winds the mainspring. We recommend that you manually wind the watch at the same time each day.Ī watch with an automatic self-winding movement has a mechanism that winds the mainspring through the motion of your wrist. Do not attempt to wind a watch past this locking point, since this might damage the movement. Winding is done by turning the crown clockwise, and is complete when the crown locks. WHAT IS THE DIFFERENCE BETWEEN A MECHANICAL HAND-WOUND MOVEMENT, AN AUTOMATIC SELF-WINDING MOVEMENT, AND A QUARTZ MOVEMENT?Ī watch with a mechanical hand-wound movement must always be wound manually by its wearer.
