Using this Diesel DZ1989 Framed watch is a breeze. Just put on the silicone strap and adjust it to fit your wrist comfortably. You can wear it during daily activities, and since it's water - resistant up to 50 meters, it can handle splashes or short swims. But don't wear it for deep - sea diving. To keep it in good shape, clean the case and strap regularly with a soft, dry cloth. Avoid exposing it to extreme temperatures or harsh chemicals. When not in use, store it in a cool, dry place. This way, your watch will stay looking great and working well for a long time.
