The beauty of a watch must serve to showcase its correct operation. For this reason, the Poinçon de Genève submits every watch to a number of tests to ensure their quality and reliability. A watch with Poinçon de Genève certification offers the assurance of a fine timepiece made using the latest technologies for reliability and precision.

Through its approval, certification and audit bodies, the Poinçon de Genève Office constantly oversees the application of its criteria throughout every stage in the manufacture of a timepiece.
A fine watch is not limited to precision timekeeping. The Poinçon de Genève ensures the correct operation of each individual function such as calendar jumps, the grande sonnerie and so on.
Water resistance is essential in order for a watch to be reliable. The slightest trace of humidity or dust could damage the movement or affect its operation. Every Poinçon de Genève watch must be tested at -0.5 and +3 bar at the minimum.
A mechanical watch is by nature not as accurate as a quartz or an atomic watch. Nonetheless, the Poinçon de Genève ensures that the image of watches made in Geneva is respected, and ensures that variations are as minute as possible.
A watch’s power reserve is the remaining energy required for its operation. The Poinçon de Genève ensures that the duration indicated by the power reserve is accurate, so that the watch does not stop unexpectedly.
