What is the method by which Rolex Datejust chronometers became COSC certified?


Rolex Datejust watches are chronometers, so they are certified timekeepers.

ISO 3159 is the testing criterion used by the Contrôle officiel suisse des Chronomètres. Certified chronometer watches must be tested and certified by the Official Swiss Chronometer Testing Institute, or COSC. Only movements meeting ISO 3159's precision requirements can be granted a chronometer certificate.

Watches that qualify for COSC certification must maintain everyday accuracy of between +6 and -4 seconds. The test criteria for a wrist chronometer with a spring balance oscillator are consistent with ISO 3159's specification. For fifteen days, five positions were tried in three distinct temperatures. Day after day, a digital video camera is used to take measurements. Each of the seven elimination criteria must be met based on these measurements. It is necessary for a COSC chronometer to have an escapement that is spring-driven.

The movement must not only be assembled by watchmakers of the highest level, but must also meet chronometer certification requirements. Only a small percentage of Swiss watches are COSC-certified. Almost always, Rolex watches are certified by the COSC. Rolex watches with the label Superlative Chronometers Officially Certified on the dial are COSC-certified.
