In this video I show and explain a very common Tuning Fork Watch Issue. I start by analyzing why the second hand moves when turning the crown on the setting position. When this happens it is usually because the cannon pinion or center wheel are too tight, or the index wheel is damaged. The index wheel is the most delicate part on these type of movements. Any force on the second hand, or train of wheel will render this part useless. Extreme care should be exercised when dealing with this type of movements.
