A mechanical movement (like NH35), dial, hands, and strap/bracelet are required to complete a functional watch. For optimal water resistance, ensure all gaskets are properly lubricated and seated, and the crown is fully screwed down before exposure to water. The unidirectional bezel is designed to prevent accidental extension of dive time by only rotating counterclockwise. Regular cleaning with a soft, dry cloth is recommended to maintain the finish. Avoid contact with harsh chemicals. (Note: Packaging dimensions and weight are not specified by the manufacturer and may vary.)
