Certina Powermatic Watch - Green

No, the Certina Powermatic watch features an automatic self-winding mechanical movement that is powered by the natural motion of the wearer's wrist.

You can wind the watch by wearing it throughout the day, or by manually turning the crown clockwise about 30-40 times when the crown is in its resting position.

The specific power reserve can vary by model, but Powermatic movements are generally known for substantial power reserves, often lasting 50 hours or more on a full wind.

Accuracy can vary, but a well-maintained automatic watch typically runs within a few seconds per day of COSC chronometer standards, though some variation is normal.

This depends on the specific water resistance rating of your watch model. Always check the specifications for your watch and ensure the crown is securely in place before any water exposure.

An analogue timepiece displays time using hands (hour, minute, second) that point to markers or numerals on a dial, as opposed to a digital display showing numbers.

Mechanical watches typically require professional servicing every 3 to 5 years to maintain their accuracy and prolong their lifespan.

Ensure the watch has been worn recently or manually wind the crown 30-40 times clockwise to build a power reserve.

If the inaccuracy is significant, the watch may require servicing. Minor deviations might occur with automatic watches and can sometimes be related to magnetic interference or needing a service.

Ensure the crown is pulled out to the correct position for setting the time. If it remains stiff, do not force it; seek professional inspection.

For leather straps, avoid prolonged exposure to water and sweat. For metal bracelets, clean gently with a soft cloth. Consider replacement if damage is significant.
