Using this Daniel Wellington watch is super easy. Just put it on your wrist like you would with any other watch. When it comes to taking it off, simply undo the clasp. For everyday use, it can handle splashes of water as it's 30 meters water - resistant, but don't go swimming or diving with it. To keep it looking great, wipe the watch and strap gently with a soft, dry cloth regularly. Avoid exposing it to harsh chemicals or extreme temperatures. If the watch stops working, it might be time to change the battery. You can take it to a professional watch repair shop for battery replacement. Also, remember that the Petite 36 straps are not interchangeable with Classic 36 straps, so don't try to swap them.
