Certina DS Action - Black Dial - 43mm

COSC (Contrôle Officiel Suisse des Chronomètres) certification means the watch movement has been independently tested and certified for high precision in various positions and temperatures, meeting strict accuracy standards.

With a 300-meter water resistance rating, this watch is suitable for recreational diving and surface water sports. For professional or deep-sea diving, a watch specifically rated for higher depths and equipped with a unidirectional bezel is generally recommended.

It is generally recommended to have a mechanical watch like the Certina DS Action serviced every 3 to 5 years to ensure optimal performance and longevity of the movement.

Yes, the stainless steel bracelet can be adjusted for size by a jeweler or watchmaker, who can remove or add links to achieve a comfortable fit.

Automatic watches wind themselves through the motion of the wearer's wrist. Manual winding requires the user to turn the crown to power the watch. This Certina DS Action is an automatic watch that can also be manually wound.

The dial itself should ideally only be cleaned by a professional during servicing. For external cleaning, use a soft, slightly damp cloth on the case and crystal, avoiding direct contact with the dial if possible.

Ensure the watch has been wound manually if it has been stationary for a prolonged period. If worn regularly, check if the crown is fully screwed down. If the issue persists, it may require servicing.

Avoid changing the date between 9 PM and 3 AM, as this is when the watch's date mechanism is engaged and changing it manually can cause damage. Refer to the user manual for correct date setting procedures outside of this window.

Minor scratches can sometimes be buffed out by a professional watch repair service. Deep scratches may be more difficult to remove completely without professional attention.

This indicates a potential breach in water resistance. Do not operate the crown or use the watch until it has been inspected and resealed by a qualified watchmaker.
