Using your Diesel DZ4360 watch is easy. Just set the time and date according to the instructions in the manual. You can use the chronograph feature to time events - start, stop, and reset it with the buttons on the side. For daily wear, it's suitable for all kinds of occasions. When it comes to water, it can handle splashes and swimming up to 100 metres, but avoid deep-sea diving. To keep it in top shape, clean it regularly with a soft, dry cloth. If the battery runs out, have it replaced by a professional to avoid any damage to the watch.
