The moon goes through an average cycle lasting 29.53 days. Depicting moon phases is a watchmaking complication which is both traditional and complex: The moon's current profile is presented through a cut-out in the dial by means of a rotating disc.

The name of an innovative technology which ensures the utmost accuracy at Certina: The timepieces with Precidrive(TM) quartz calibres achieve real chronometer precision. With a rate deviation of +/-10 seconds per year, a Precidrive(TM) timepiece is around eight to ten times more accurate than traditional quartz timepieces.

Some Certina quartz timepieces - and all Precidrive(TM) models without exception, whether a three-hand variant or a chronograph - have an end of life (EOL) indicator. It indicates that the battery has reached the end of its life: When this is the case, the seconds hand continues to move, but in four-second increments only, and the battery should be replaced within the next two weeks.

A timepiece is only permitted to be called a chronometer if it has been awarded a certificate of precision as a result of passing demanding tests set by an independent test institute. The "Contrôle Officiel Suisse des Chronomètres", known as COSC for short, is the official Swiss chronometer testing institute, which certifies both mechanical calibres and quartz movements.
