Using this Christmas watch is super easy. First, find a nice spot on your wall where you want to display it. Since it's lightweight (only 1.6 kg), you can use a simple wall - hanging hook to put it up. Then, open the battery compartment and insert the appropriate batteries as per the power type (battery - operated). As for maintenance, keep it away from water and excessive heat. If it gets dirty, you can gently wipe it with a dry cloth. Just be aware that the color you see on your screen might be a bit different from the real watch because of monitor settings.
