Functioning of the watch

  • A chronograph is a timepiece which, in addition to displaying the time, is equipped with a stopwatch mechanism to measure and record elapsed time. Depending on the model, the measured time is shown either by an analogue display with an hour, minute, second and even a 1/10 or 1/100 second hand or by a digital display. A chronometer is a watch that has obtained an official rate certificate from the COSC (Contrôle Officiel Suisse des Chronomètres), which certifies that the movement has passed a range of precision tests in different positions and at different temperatures over a 15-day period. Certification can be granted both for mechanical and quartz movements.
  • A self-winding mechanical Certina movement depends on the wrist motions of the wearer for its operation. When fully wound, the watch has a power reserve of 38-42 hours. Since the watch's self-winding mechanism is directly linked to the wearer's activity, 10 to 12 hours' wear should be sufficient to generate a power reserve of 20 hours or more, which ensures that the watch will continue to run throughout the night. However, if a watch has not been worn for several days and its power reserve has thus run low, we recommend you wind the watch manually for around 15 rotations of the crown (clockwise) to ensure the best possible rate from the outset.
  • You can find tips on the right way to handle your watch under “Instructions for use”. Furthermore, we recommend that you take your watch to be serviced at an official Certina service centre every three to four years.
  • To earn the title of chronometer, a watch must be equipped with a movement that has obtained an official rate certificate from the COSC (Contrôle Officiel Suisse des Chronomètres). To obtain this, precision tests in different positions and at different temperatures must be carried out. These tests take place over a 15-day period.At Certina, all quartz chronometers are equipped with the innovative Precidrive™ movement which, with a deviation of +/- 10 seconds per year, easily achieves the required precision ratings.
  • A unidirectional bezel only turns one way to prevent any danger of false manoeuvre. This is especially important when being used to measure diving times as even if the bezel is knocked and moved it will simply indicate the diver has less air or decompression time rather than more.
  • The accuracy of the watch depends on the movement and on the individual habits of the wearer and can therefore vary. A qualified Certina watchmaker can adjust the rate precision of a watch to be within Certina tolerances. The majority of watches that do not have a chronometer certificate have average precision tolerances of between -5 / +30 seconds per day. To qualify for the “chronometer” label, a mechanical movement’s average variation in rate must be between -4 / +6 seconds per day.
  • Certina sport watches set the standard in water resistance. For water sports, a timepiece with a minimum water resistance of 10 bar (100 m) is recommended. All Certina sports watches are equipped with the \DS\" concept and tested to a minimum pressure of 10 bar in accordance with the relevant ISO standards.It should also be understood that water resistance cannot be guaranteed for an indefinite length of time. It may become compromised by ageing of the seals or impacts to the crown or push-buttons. Certina therefore recommends that you have the timepiece regularly checked for water resistance by an authorised Certina Service agent, and have any faulty components replaced. Do not attempt to open the timepiece yourself under any circumstances."
  • A tachymeter is an instrument for measuring speed. It is a chronograph with a graduated dial on which speed can be read off in kilometres per hour based on a 1000 metre distance. How to read the tachymeter: Only the central chronograph seconds hand is used. For longer durations, the indications of the timers (minutes and hours) also count. Example for calculating the speed of a car: The chronograph indicates that the distance of one kilometre has been covered in 30 seconds. The corresponding point on the tachymeter scale indicates 120. The speed is therefore 120 km per hour.
  • Precidrive™ is the name of an innovative technology that makes Certina watches extremely accurate. Watches with Precidrive™ quartz calibres achieve true chronometer precision. With a variation in timekeeping of just +/-10 seconds per year, a Precidrive™ watch is 8 to 10 times more accurate than a conventional quartz watch.
  • Certina quartz movements are produced in accordance with Certina’s highly renowned quality standards and manufacturing methods. Ambient temperature (20°-25°) can affect the precision of quartz movements and lead to variations of between +/- 80 to 85 seconds per year.

Maintenance services

  • A battery normally lasts between two and five years, depending on the type of watch, its size and the amount of energy it requires to operate the various functions. For example, a chronograph uses more energy than a watch that only displays the hours and minutes. Many Certina watches (all the Precidrive™ watches) have an end-of-life (EOL) display (three-hand models): when the second hand begins to jump every four seconds, the battery needs changing by a qualified Certina watchmaker.
  • A 24-month guarantee is provided for all watches from the date of purchase, in accordance with the general warranty terms and conditions. Even for general repairs there is a 24-month guarantee for any work carried out.GuaranteeThe international Certina guarantee covers material and manufacturing defects existing at the time of delivery of the purchased Certina watch (\defects\").

  • Certina watches should always only be serviced by an official Certina service centre. If the watch is repaired by a watchmaker who does not have official Certina certification, the guarantee does not apply. You can find a complete list of our service centres under the “Find a service centre” tab.
  • For technical and quality reasons, we do not deliver individual replacement parts directly to our customers. The Certina World Customer Service Centre is available to all customers and offers a professional service which meets Certina's high quality standards.
  • Certina guarantees repairs and the delivery of replacement parts for at least 10 years for standard watches and up to 20 years for gold watches from the date production is discontinued. Certina will do its utmost to ensure that repair of collector's pieces and jubilee watches can be carried out.
  • You will find a list of prices under the “Service costs” tab. This will give you an idea of how much a service costs. A wide range of international regulations prevent us from setting exact prices. As a result, the different Certina service centres set their own service prices. However, the non-binding price recommendations on this page apply in all countries with an official Swatch Group AG service centre.

Materials

  • The materials Certina uses are subject to very strict tests in order to prevent an allergic reaction. The stainless steel (316L) used in Certina watches contains a small amount of nickel, but this is not released and so there is no danger for persons with a nickel allergy. However, Certina recommends that persons who have a sensitive reaction to stainless steel should buy a titanium or gold watch or one with a PVD coating.
