Using this Diesel watch is easy. Just put it on your wrist and adjust the bracelet to fit comfortably. The automatic movement means it winds itself as you move, so you don't need to worry about winding it manually. When it comes to care, avoid exposing the watch to extreme temperatures or chemicals. Don't wear it while swimming or showering, even though it's water - resistant up to 30 meters, as long - term water exposure can still damage it. To clean the watch, use a soft, dry cloth to gently wipe the case and bracelet. If you notice any issues with the movement or the water resistance, it's best to take it to a professional watch repair service.
