Chronofiable is a Swiss-made watch certification system developed by the Besançon Observatory in France. It is designed to test a watch’s accuracy, precision and reliability over time, and is considered one of the most rigorous and reliable watch testing systems available. Chronofiable tests include accuracy, power reserve, water resistance and shock resistance, and the results are displayed on a certificate provided with each tested watch. Chronofiable certification is a mark of quality and a guarantee of precision and reliability.
