Using this Diesel DZ1986 Framed watch is easy. Just put it on your wrist like any other watch. The silicone strap is flexible and comfortable, so you can wear it all day. For time adjustment, you can gently pull out the crown on the side of the case and turn it to set the correct time. When it comes to care, keep it away from strong magnetic fields as they can affect the quartz movement. You can clean the watch with a soft, damp cloth to keep it looking good. Since it's water - resistant up to 50 meters, it can handle splashes and short swims, but don't use it for deep - sea diving.
