In taking a Geneva lever watch apart, first remove it from its case; then lever off the hands, remove the dial, and take off the motion wheels underneath it. Next remove the central set-hand arbor by knocking it out with a Light tap. It is friction-tight only in both the cannon pinion and the centre wheel. Then let down the mainspring by a key on the winding square while holding the click back. Take out the balance, pallets, 'scape wheel, train wheels, centre wheel, and barrel in the order named.
