Setup, Compatibility & Care
To keep your Zenith Chronomaster in peak condition, ensure the crown is fully pushed in after adjusting the time to maintain its 50-meter water resistance. The watch is self-winding, but if it has sat dormant, rotate the crown clockwise in the '0' position to jumpstart the mainspring. Avoid engaging the chronograph pushers while underwater. Clean the steel case and bracelet regularly with a soft, lint-free cloth and mild soapy water to remove sweat or debris, taking care to rinse and dry thoroughly to prevent finish tarnishing. For service, it is recommended to visit an authorized Zenith service center to ensure the complex El Primero movement is calibrated by trained technicians.
