To use this Liverpool FC die - cast metal wall clock, first, find a suitable spot on your wall. You can use a nail or a wall hook to hang it. Then, insert 1 x AA battery (which you'll need to buy separately). Once the battery is in, the clock will start working right away. As for maintenance, keep it away from water and extreme temperatures. You can use a dry cloth to wipe off any dust. If the clock stops working, check the battery first and replace it if needed.
