Using your Diesel Mega Chief DZ4329 Chronograph is easy. To set the time and date, find the crown on the side of the watch. Pull it out gently to different positions to adjust the time and set the date. When you're out for a swim or in contact with water, don't worry as it can handle up to 100 meters of water pressure. Just make sure to dry it thoroughly after getting wet. For maintenance, clean the watch regularly with a soft, dry cloth. Avoid exposing it to extreme temperatures or chemicals, as this can damage the watch. Also, if you notice any issues with the movement or the clasp, it's best to take it to a professional watch repair service.
