GMT watches also give wearers the opportunity to display another time zone, which can be set as they wish, in addition to the "main time". This information is usually provided by means of a separate hand on a 24-hour scale, making it possible to read the local time and home time at a glance when you are on the move, for instance.

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.

The time zone mechanism enables modern cosmopolitans to adjust the time on their watch to a new time zone in an instant - without losing even a single second: When the crown is pulled to the first position, the hour hand can be set in one hour increments on models with a time zone mechanism, without interrupting the minutes and seconds.
