Wind the clock once per week, preferably on the same day each week.

Turn the key with a smooth motion, stopping when the spring is tight (approximately 7 turns after one week of running).

Never let the key snap back in your hand, always release it gently after each half turn. (Make sure the clock is fully wound, so keep turning the key until the spring is obviously tight).

The left square winds the strike mainspring and, the right square winds the time mainspring.
