Using this Diesel Men's DZ1973 MS9 Punk Spirit Wristwatch is a breeze. Just fasten the leather strap around your wrist, and you're good to go. When it comes to maintenance, keep it away from water for long periods as it may damage the internal parts. Wipe it with a soft, dry cloth regularly to keep it looking shiny. If you're not wearing it, store it in a cool, dry place. Avoid hitting it against hard objects to prevent scratches on the stainless - steel body and the watch face.
