The beauty of a watch must serve to showcase its correct running. On this way, the Poinçon de Genève submits every watch to a testing plan to ensure quality and reliability. A watch certified Poinçon de Genève is a guarantee of an authentic, accurate and reliable timepiece carried out by the most up to date technology.

Quality assurance 

Through its approval, certification and audit bodies, the Poinçon de Genève Office constantly oversees the application of its criteria throughout every stage of the timepiece manufacturing.

Functional test

A fine watch is not limited to the accuracy of timekeeping. The Poinçon de Genève ensures the correct running of each individual function such as calendar jumps, the grande sonnerie and so on.

Water resistance

Water resistance is a key feature for a reliable watch. The slightest trace of humidity or dust could damage the movement or affect its running. Every Poinçon de Genève watch must be tested at -0.5 and +3 bar minimum.


A mechanical watch is by its conception not as accurate as a quartz or an atomic watch. Nonetheless, the Poinçon de Genève ensures that the recognition of watches made in Geneva is respected, and that  time lag is as insignificant as possible.

Power reserve

For a watch, a power reserve is the remaining energy required for its running. The Poinçon de Genève ensures that the duration indicated by the power reserve is accurate in order to avoid an unexpected stop.
