Setup, Compatibility & Care
To keep your Zenith Defy Classic in optimal condition, ensure the crown is fully pushed in after setting the time and date to maintain its 100-meter water resistance. Because the movement is automatic, daily wear is typically sufficient to keep it fully wound; however, if the watch remains stationary for more than two days, manually winding the crown 20-30 times is recommended. Clean the carbon case and sapphire crystal using a soft, lint-free cloth. Avoid harsh chemicals or ultrasonic cleaners, as these may damage the specialized finishes or internal gaskets. It is recommended to have the movement serviced by an authorized Zenith service center every 3 to 5 years to ensure the longevity of the chronometer-certified caliber.
