Open the glass bezel on the front and insert the key into the small holes on the dial. Most have two holes. One winds the time and the other winds the strike mechanism.
Always turn the key gently in a clockwise direction until you feel solid resistance. Stop when it feels tight to avoid breaking the mainspring.
The movement is likely out of beat. This happens when the case sits unevenly on the surface, causing the pendulum to swing further to one side.
You can often fix this by adjusting the small screw feet under the base. Listen to the tick as you adjust them until the sound is even on both sides.

Never use standard metal polish or abrasive cloths. They will strip the thin gold layer right off the base.
Just dust it with a soft dry brush.

You can have a plain brass replacement cut to fit the aperture. It protects the movement from dust, even if it lacks the decorative piercing.
